That means if you click and purchase, we may get a commission. It's how we keep this site running without cluttering it with ads. Good wool socks can only hold onto the heat you've got. Stand still on a frozen Saskatchewan lake, wait for a Winnipeg bus at -30°C, or put in a long outdoor shift in Sudbury, and that heat runs out. Heated socks use rechargeable battery packs and thin heating elements to target the areas that tend to go cold first, usually the toes, forefoot, or sole. They are a practical extra layer, not a replacement for dry boots, room for circulation, and sensible time limits in severe weather. Our recommendations are curated from published specifications, listed features, prices, ratings, and buyer feedback. The right pair depends less on the highest claimed temperature than on your footwear, how long you will be out, and where the heat is placed. A skier in snug boots needs a low-profile system; a hunter sitting in a blind may put runtime ahead of bulk. For Canadian conditions, battery access, calf fit, and a heat setting you can turn down matter as much as headline capacity. Most of the picks here are sold on Amazon.ca, but Canadian Tire, Sport Chek and MEC also stock heated socks in season if you'd rather see a pair in person. ## Quick Overview: Our Top Picks | Product | Best For | Why We Love It | Price | | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | ------------------------ | -------------------------------------------------------------------------------------------------------- | ----------- | | ![SNOW DEER rechargeable heated socks with 7.4V battery for cold-weather outdoor use](https://storage.ghost.io/c/65/8b/658bb4e9-9316-49de-aa33-8d03ee59bdfd/content/images/2026/10/B07T3WTVHG.jpg) **[SNOW DEER Heated Socks](https://www.amazon.ca/dp/B07T3WTVHG?tag=thecanadarepo-20&ref=thecanadareport.ca)** | Everyday winter warmth | Rechargeable warmth suits commuting, outdoor chores, riding, camping, and other cold-weather activities. | $99.99 CAD | | ![Nodinsy heated socks for men and women with dual 7000mAh rechargeable batteries](https://storage.ghost.io/c/65/8b/658bb4e9-9316-49de-aa33-8d03ee59bdfd/content/images/2026/10/B0H5QX1279.jpg) **[Nodinsy Heated Socks](https://www.amazon.ca/dp/B0H5QX1279?tag=thecanadarepo-20&ref=thecanadareport.ca)** | Long outdoor days | Large-capacity batteries promise up to 11 hours of warmth for extended winter activities. | $79.99 CAD | | ![Spossoc rechargeable heated socks with app control for men and women](https://storage.ghost.io/c/65/8b/658bb4e9-9316-49de-aa33-8d03ee59bdfd/content/images/2026/10/B0H6B8C7N3.jpg) **[Spossoc Heated Socks](https://www.amazon.ca/dp/B0H6B8C7N3?tag=thecanadarepo-20&ref=thecanadareport.ca)** | App-controlled comfort | App controls, timed heating, and broad temperature adjustment make warmth easy to personalize. | $88.99 CAD | | ![SAVIOR HEAT rechargeable heated socks with app control for warm toes](https://storage.ghost.io/c/65/8b/658bb4e9-9316-49de-aa33-8d03ee59bdfd/content/images/2026/10/B0DF7B2XGN.jpg) **[SAVIOR HEAT Heated Socks](https://www.amazon.ca/dp/B0DF7B2XGN?tag=thecanadarepo-20&ref=thecanadareport.ca)** | All-around foot coverage | Heating above and below the forefoot and toes provides more comprehensive warmth than toe-only designs. | $109.99 CAD | | ![FREEHILL merino wool rechargeable heated socks with toe and full sole warming](https://storage.ghost.io/c/65/8b/658bb4e9-9316-49de-aa33-8d03ee59bdfd/content/images/2026/10/B0DDPCLH9Y.jpg) **[FREEHILL Merino Heated Socks](https://www.amazon.ca/dp/B0DDPCLH9Y?tag=thecanadarepo-20&ref=thecanadareport.ca)** | Merino on a budget | Toe-and-full-sole heating in a merino blend with flat cables that suit ski and work boots. | $59.49 CAD | | ![HONGYI rechargeable heated socks with batteries for warm feet in cold weather](https://storage.ghost.io/c/65/8b/658bb4e9-9316-49de-aa33-8d03ee59bdfd/content/images/2026/10/B0HHMZB927.jpg) **[HONGYI Heated Socks](https://www.amazon.ca/dp/B0HHMZB927?tag=thecanadarepo-20&ref=thecanadareport.ca)** | Flexible heat settings | Four heat levels, including a strong setting, let you fine-tune warmth for changing conditions. | $54.99 CAD | | ![FREEHILL 7.4V heated wool socks with rechargeable 16-hour battery for men and women](https://storage.ghost.io/c/65/8b/658bb4e9-9316-49de-aa33-8d03ee59bdfd/content/images/2026/10/B0HDY3XLKC.jpg) **[FREEHILL Wool Heated Socks](https://www.amazon.ca/dp/B0HDY3XLKC?tag=thecanadarepo-20&ref=thecanadareport.ca)** | Longest battery runtime | Premium wool comfort, rapid heating, and claimed runtime up to 16 hours suit full winter days. | $109.99 CAD | ### [SNOW DEER Heated Socks](https://www.amazon.ca/dp/B07T3WTVHG?tag=thecanadarepo-20&ref=thecanadareport.ca) ![SNOW DEER rechargeable heated socks with 7.4V battery for cold-weather outdoor use](https://storage.ghost.io/c/65/8b/658bb4e9-9316-49de-aa33-8d03ee59bdfd/content/images/2026/10/B07T3WTVHG.jpg) SNOW DEER heated socks deliver rechargeable warmth for winter activities SNOW DEER is the straightforward pick for skiers, riders, and winter walkers who want heat focused exactly where cold starts: the whole toe area plus the top and bottom of the foot. Its 7.4V, 2200mAh rechargeable batteries and three heat levels keep the setup simple, with controls on the socks rather than dependent on an app. Buyers frequently praise the practical on-sock controls and warmth for skiing, while one recurring caution concerns the effort of removing and reinstalling the batteries. That makes it a sensible choice for someone who values direct adjustment and broad foot coverage, but less appealing if you expect to swap packs repeatedly during an outing. The polyester construction is also a more technical, synthetic-oriented option than a wool blend. [Check SNOW DEER Heated Socks on Amazon](https://www.amazon.ca/dp/B07T3WTVHG?tag=thecanadarepo-20&ref=thecanadareport.ca) for current availability. #### Pros - Heating elements cover the toes plus the top and bottom of the foot - Three heat levels are controlled directly on the socks - Two rechargeable 7.4V 2200mAh batteries are included #### Cons - Buyer feedback flags fiddly battery removal and reinstallation - No wool content is listed for passive insulation ### [Nodinsy Heated Socks](https://www.amazon.ca/dp/B0H5QX1279?tag=thecanadarepo-20&ref=thecanadareport.ca) ![Nodinsy heated socks for men and women with dual 7000mAh rechargeable batteries](https://storage.ghost.io/c/65/8b/658bb4e9-9316-49de-aa33-8d03ee59bdfd/content/images/2026/10/B0H5QX1279.jpg) Nodinsy heated socks with dual 7000mAh rechargeable batteries Nodinsy suits the person planning long, lower-intensity days outside: an ice-fishing trip, a hunting blind, winter camping, or a lengthy outdoor shift. Its main case is endurance, with two 7000mAh batteries and a claim of up to 11 hours of warmth. It also supports Android and iOS app control, allowing adjustments without unpacking your feet from boots. A one-year warranty adds useful reassurance for an electronic winter item. Heat covers the toes and sole (not the heel) across four levels from 35°C to 65°C. Choose it when stated battery capacity and all-day potential matter most. This link goes to the Large size (men's 9–14), so check the size dropdown. [Check Nodinsy Heated Socks on Amazon](https://www.amazon.ca/dp/B0H5QX1279?tag=thecanadarepo-20&ref=thecanadareport.ca) for current availability. #### Pros - Two 7000mAh batteries with a stated runtime of up to 11 hours - Android and iOS app control - One-year warranty is listed #### Cons - No heating under the heel - This link goes to the Large size (men's 9–14), so check the size dropdown ### [Spossoc Heated Socks](https://www.amazon.ca/dp/B0H6B8C7N3?tag=thecanadarepo-20&ref=thecanadareport.ca) ![Spossoc rechargeable heated socks with app control for men and women](https://storage.ghost.io/c/65/8b/658bb4e9-9316-49de-aa33-8d03ee59bdfd/content/images/2026/10/B0H6B8C7N3.jpg) Spossoc heated socks offer app-controlled warmth for cold-weather adventures Spossoc is a feature-rich choice for someone who wants close control during changing conditions. It combines app adjustment with three heat settings, a 0-to-120-minute timer, and listed temperatures from 40°C to 60°C. The two 5000mAh batteries have a stated runtime of up to 10 hours, while the design claims 360-degree heat coverage, a cushioned heel, and an ergonomic collar intended to stay in place. Buyers commonly describe the material as soft and comfortable, though the review pool is smaller than some established listings. Pick it for camping, skiing, or cold evenings when timed heat and app control are genuinely useful. Its main compromise is extra complexity: a timer and phone controls are helpful only if you will remember to set and charge them. [Check Spossoc Heated Socks on Amazon](https://www.amazon.ca/dp/B0H6B8C7N3?tag=thecanadarepo-20&ref=thecanadareport.ca) for current availability. #### Pros - App control, three heat settings, and a 0-to-120-minute timer - Two 5000mAh batteries with up to 10 hours of claimed warmth - Listed 360-degree coverage, cushioned heel, and fitted collar #### Cons - More controls mean more setup than a simple button-operated pair - The available buyer-feedback base is relatively modest ### [SAVIOR HEAT Heated Socks](https://www.amazon.ca/dp/B0DF7B2XGN?tag=thecanadarepo-20&ref=thecanadareport.ca) ![SAVIOR HEAT rechargeable heated socks with app control for warm toes](https://storage.ghost.io/c/65/8b/658bb4e9-9316-49de-aa33-8d03ee59bdfd/content/images/2026/10/B0DF7B2XGN.jpg) SAVIOR HEAT heated socks with app control and rechargeable batteries SAVIOR HEAT is the balanced option for active Canadians who want a phone app without giving up physical controls. You can use the app to adjust warmth without removing shoes, then fall back on the sock button when a phone is inconvenient. Its heating elements sit above and below the forefoot and toe area, a targeted layout for skiing, walking, cycling, and outdoor work. Three modes are listed from about 40°C to 65°C, with a claimed 3-to-9-hour runtime from two 7.4V 2200mAh batteries. Buyer reports are encouraging on connection reliability and forefoot warmth in hard cold. The trade-off is endurance at high output: it is not the clearest choice for a very long stationary day. [Check SAVIOR HEAT Heated Socks on Amazon](https://www.amazon.ca/dp/B0DF7B2XGN?tag=thecanadarepo-20&ref=thecanadareport.ca) for current availability. #### Pros - Both app and button control are available - Heating elements cover above and below the forefoot and toes - Three heat modes with a stated 3-to-9-hour runtime #### Cons - Battery capacity is smaller than the longest-runtime options - The listed warmth is focused on the forefoot rather than a full sole ### [FREEHILL Merino Heated Socks](https://www.amazon.ca/dp/B0DDPCLH9Y?tag=thecanadarepo-20&ref=thecanadareport.ca) ![FREEHILL merino wool rechargeable heated socks with toe and full sole warming](https://storage.ghost.io/c/65/8b/658bb4e9-9316-49de-aa33-8d03ee59bdfd/content/images/2026/10/B0DDPCLH9Y.jpg) FREEHILL heated merino socks warm toes and full soles FREEHILL Merino Wool Rechargeable Heated Socks are the value-oriented pick for people who wear ski, hiking, or work boots and want a wool blend rather than an all-synthetic sock. The heating reaches the toes and full sole, and the listing emphasizes flat heating cables with stretch knit to reduce bulk inside boots. Three heat levels use a one-click control, while the 5V battery system is said to recharge in about five hours. Buyers mention comfort, but a candid review warns that the socks can feel tight at the calf and that the packs are heavy and bulky. That caveat matters. Choose this pair for a reasonably priced toe-and-sole design if your calves and boot shafts have room; skip it if cuff pressure is already a problem. [Check FREEHILL Merino Heated Socks on Amazon](https://www.amazon.ca/dp/B0DDPCLH9Y?tag=thecanadarepo-20&ref=thecanadareport.ca) for current availability. #### Pros - Merino blend and full-sole plus toe heating - Flat heating cables are intended to suit ski, hiking, and work boots - Three-level one-click control and about five-hour stated recharge time #### Cons - Buyer feedback notes a tight calf fit for some people - Battery packs may feel heavy or bulky ### [HONGYI Heated Socks](https://www.amazon.ca/dp/B0HHMZB927?tag=thecanadarepo-20&ref=thecanadareport.ca) ![HONGYI rechargeable heated socks with batteries for warm feet in cold weather](https://storage.ghost.io/c/65/8b/658bb4e9-9316-49de-aa33-8d03ee59bdfd/content/images/2026/10/B0HHMZB927.jpg) HONGYI rechargeable heated socks provide cozy warmth in winter HONGYI is the accessible choice for occasional use: snow shovelling, dog walks, a few hours of fishing, or a newcomer who wants four heat levels without paying for app features. Its settings run from 38°C to 62°C, and two rechargeable batteries have a stated 4-to-8-hour heating range. The listed size range covers women’s 5 to 9.5 and men’s 6 to 8.5, so it is not a universal answer despite the unisex presentation. Buyer feedback suggests good warmth and respectable low-setting endurance, including in very cold conditions, but also identifies loose calf fit and battery packs that can slip from their pockets while walking. It is a reasonable budget entry, with a more hands-on fit-and-pocket compromise than pricier models. [Check HONGYI Heated Socks on Amazon](https://www.amazon.ca/dp/B0HHMZB927?tag=thecanadarepo-20&ref=thecanadareport.ca) for current availability. #### Pros - Four adjustable heat levels - Stated 4-to-8-hour battery range - Buyer feedback reports useful warmth and solid low-setting endurance #### Cons - Battery pockets may need attention during walking - Calf fit may be loose for some wearers ### [FREEHILL Wool Heated Socks](https://www.amazon.ca/dp/B0HDY3XLKC?tag=thecanadarepo-20&ref=thecanadareport.ca) ![FREEHILL 7.4V heated wool socks with rechargeable 16-hour battery for men and women](https://storage.ghost.io/c/65/8b/658bb4e9-9316-49de-aa33-8d03ee59bdfd/content/images/2026/10/B0HDY3XLKC.jpg) FREEHILL heated wool socks deliver fast, lasting warmth for cold-weather adventures FREEHILL Ultimate Wool is aimed at the person who spends serious time outside in deep Canadian cold and wants passive insulation alongside battery heat. The fabric is listed as more than 50% wool with Coolmax fibres, and its 7.4V system claims up to 16 hours of battery life. A pre-heat mode automatically moves to Medium, while a four-LED display shows battery status. Most notably, the manufacturer states that the module operates at -20°C. That makes it the clearest candidate here for very cold job sites, ice fishing, and long winter outings. The honest downside is bulk and price positioning: it is listed at 650 g, and its short review history is less reassuring than options with thousands of ratings. Check boot volume before buying. [Check FREEHILL Wool Heated Socks on Amazon](https://www.amazon.ca/dp/B0HDY3XLKC?tag=thecanadarepo-20&ref=thecanadareport.ca) for current availability. #### Pros - More than 50% wool with Coolmax fibres is listed - Up to 16 hours of claimed battery life and a four-LED power display - Manufacturer states operation at -20°C #### Cons - Listed item weight is 650 g, which may matter in close-fitting boots - It has a much smaller review count than several alternatives ## What to Look for in Heated Socks Start with heat placement. Socks that warm the toes and forefoot address the most common cold spots, while full-sole designs can make more sense for stationary work, snowshoeing, or long walks. Next, look at the battery system and the stated runtime at the setting you expect to use. A long maximum runtime is useful, but cold weather and higher settings generally demand more power. Fit is not a minor detail. A heated sock that crowds a ski boot or constricts the calf can work against circulation and comfort. Check the listed shoe-size range, battery-pocket position, and fabric composition. Wool blends can add passive warmth and moisture management; polyester options may suit people prioritizing stretch and a lighter feel. Finally, choose controls you will actually use. A cuff button is simple with gloves off, while app control can be handy when boots are already laced. ## Types of Heated Socks and How They Work Most heated socks in this guide are rechargeable, battery-powered socks. Each sock connects to a small battery pack, usually carried in a pocket near the upper cuff. Flexible heating elements run through selected areas of the foot and are switched between preset heat levels by a button, an app, or both. The useful distinction is coverage, not marketing language. Toe-only or forefoot heating is focused and can suit skiing, cycling, and active outdoor work, where a heavy or thick sole may be unwelcome. Toe-and-full-sole heating spreads warmth under the foot, a better match for people who stand still in cold conditions. Some models also offer a timer or a pre-heat function. These features help manage output, but they do not remove the need to begin with dry socks and boots that leave enough room for your feet. If your hands go cold before your feet do, our guide to [heated gloves in Canada](https://www.thecanadareport.ca/best-heated-gloves-canada/) covers the same battery tech for your fingers. ## Power Options: Battery Life, Charging, and Portability Battery capacity and voltage tell only part of the story. The listed pairs range from systems claiming roughly 3 to 9 hours through options claiming 10, 11, or up to 16 hours in favourable settings. Those top figures should be treated as maximum claims rather than a guarantee for a hard Prairie cold snap. High heat drains a battery faster, and a spare set can be more valuable than chasing a single large runtime number. For a commute or a short dog walk, a modest pack and simple three-level control may be enough. For an all-day hunt, outdoor shift, or remote snowmobile outing, prioritize stated low-setting endurance, a power indicator, and a charging routine that happens the night before. Battery packs add weight near the calf, so check that your boot top and pant cuff will not press on them. ## Sizing, Fit, and Comfort for Everyday Wear Treat heated socks as part of your boot system. The sock needs enough stretch to stay up, yet the boot must still leave room around the foot. Packing a thick heated sock into an already-tight insulated boot can reduce circulation, which is the opposite of the intended result. Measure against the seller’s size chart when one is supplied instead of relying only on your usual sock size. Calf fit deserves equal attention. Buyer feedback on some one-size options points to looser cuffs and battery pockets that may need watching during active use. People with larger calves should favour a model offered in several sizes or one specifically described with an elastic, fitted cuff. Wool-rich fabric is appealing for everyday wear because it contributes warmth even with the power off, while flat heating cables can help reduce pressure inside ski, work, and hiking boots. ## Heat Coverage and Temperature Control Three heat levels are the common baseline and are usually enough for most Canadian errands and outdoor activities. Four levels offer a little more adjustment, while app-controlled models can let you change output without removing footwear. The strongest setting is best viewed as a short-term boost for a cold start, not necessarily the setting to leave on all day. Coverage makes a larger practical difference than a small temperature claim. Cold toes are the main complaint for many winter users, so heat above and below the forefoot is a sensible design for skiing and walking. A full-sole element may feel more relevant for snow clearing, hunting, or a stationary job. One listed model provides settings from 40°C to 60°C plus a timer; another lists roughly 40°C to 65°C settings. Start low or medium, then increase only if needed. ## Durability and Wash Care Heated socks contain wiring, connectors, battery pockets, and removable batteries, so care matters more than with ordinary winter socks. Follow the manufacturer’s instructions for each pair rather than assuming that every model can be treated the same way. Remove batteries before any permitted cleaning, inspect the connector and pocket after use, and allow the socks to dry completely before reconnecting power. For days when you don't need battery heat at all, a good pair of [regular socks for winter boots](https://www.thecanadareport.ca/best-socks-for-winter-boots-canada/) is far easier to care for. Do not make a purchase on a vague assumption that all heated socks are machine washable. The Spossoc listing identifies its socks as washable, but the exact cleaning method still belongs in its product instructions. Buyer feedback also flags a practical durability issue: repeated battery removal and reinsertion can put stress on wires or pockets. Handle those connections gently, avoid yanking the cable, and choose a pair with a battery arrangement you can manage in your usual footwear. ## Safety Considerations for Heated Socks Use heated socks as controlled warmth, not as a reason to ignore numbness, wet feet, damaged skin, or worsening cold exposure. Check the socks, leads, connectors, and batteries before heading out. Do not use a pair with visibly damaged wiring, a torn battery pocket, or a battery that appears swollen or unusually hot. Keep the battery system dry and use the supplied or specified charging equipment. Begin on a lower setting, especially indoors or when your feet are already warm. High heat can be unnecessary under heavily insulated boots. People with reduced sensation in their feet, circulation concerns, diabetes, or another medical condition affecting heat sensitivity should seek advice from a qualified health professional before using electrically heated footwear. In severe weather, turn back if your feet become numb or painful; powered socks are not protection against frostbite on their own. Deep cold is a real risk, as a [deadly -18°C cold snap in Laval](https://www.thecanadareport.ca/laval-senior-death-cold-snap/) showed. ## Best Heated Socks for Different Activities in Canada For alpine skiing and snowboarding, pick a pair with targeted forefoot heat and a profile that suits fitted boots. SAVIOR HEAT and the lower-priced FREEHILL merino model both emphasize forefoot or sole coverage and boot-friendly construction. For ice fishing, hunting, or long static shifts, battery duration and broad coverage take priority; Nodinsy’s claimed 11-hour runtime, Spossoc’s claimed 10-hour runtime, and FREEHILL’s 16-hour claim are the logical options to examine. Outdoor workers may prefer physical buttons over relying only on a phone, particularly when gloves, snow, and a busy shift are involved. SNOW DEER’s controls are on the sock, while SAVIOR HEAT offers both button and app control. For ordinary winter chores, a four-level option such as HONGYI gives simple adjustment at a more accessible entry point. Match the sock to the longest, coldest use you actually expect. ## How to Choose the Right Heated Socks for Your Climate and Footwear In coastal rain and slush, dry boots and moisture management come first; a wool blend with Coolmax fibres has a sensible role alongside heat. In dry interior cold, a higher-output system and toe coverage can be more useful, particularly when temperatures move well below freezing. For a listed operating claim at -20°C, FREEHILL’s Ultimate Wool model is the clear match, although no sock can compensate for wet footwear or prolonged exposure. If your boots already feel snug, it may be worth looking at [winter boots for wide feet](https://www.thecanadareport.ca/best-winter-boots-wide-feet-canada/) before adding a heated sock. Bring the boots into the decision. Ski boots need the least bulk, while tall work boots may accommodate larger cuff packs more easily. If your boots end near the calf pocket, walk and flex in your normal setup before committing to a long day outside. Choose a lower setting for active pursuits and reserve extra output for sitting, standing, or waiting. That approach extends stated battery life and avoids overheating once you start moving. ## Frequently Asked Questions About Heated Socks in Canada ### Which heated socks offer enough battery life for a full Canadian winter day? For the longest claimed endurance, consider the FREEHILL Ultimate Wool model, which lists up to 16 hours, or Nodinsy, which lists up to 11 hours. Spossoc lists up to 10 hours. These are manufacturer claims and will vary with heat level and conditions, so a full day outside is more realistic on low or moderate heat than on high. Charge fully before leaving and consider a backup plan for remote outings. ### Are app-controlled heated socks worth choosing over button-controlled socks? App control is worthwhile if you want to adjust heat after your boots are on or check battery information from your phone. Spossoc and SAVIOR HEAT offer app control, and SAVIOR HEAT also retains button control. A button-only sock remains a strong choice for people who prefer fewer steps, do not want to use a phone outside, or need a straightforward control during work. ### Which heated socks fit comfortably inside ski or work boots? The FREEHILL Merino Wool model is specifically described with flat heating cables and stretch-knit fabric intended for ski, hiking, and work boots. SAVIOR HEAT places heating around the forefoot and toe area, which can also suit fitted winter footwear. Fit still depends on your boot volume and calf size. Do not size up a sock blindly if it leaves too little room in the boot. ### Should I choose merino wool or synthetic heated socks for outdoor winter use? Choose a wool blend if you want passive warmth and moisture management alongside battery heat. The two FREEHILL options use wool-focused constructions, with the Ultimate Wool model listing more than 50% wool plus Coolmax fibres. A polyester sock can be a sensible choice if its sizing, heat coverage, controls, and battery arrangement better suit your needs. Dry boots and a non-restrictive fit matter with either fabric. ### Which heated socks can operate at -20°C for Canadian outdoor use? FREEHILL’s Ultimate Wool heated socks are the pair in this guide with a stated operating claim at -20°C. SAVIOR HEAT buyer feedback includes use in temperatures around -18°C, but that is an individual report rather than a manufacturer operating specification. In either case, use dry insulated boots, monitor your feet, and avoid treating a heated sock as standalone cold-weather protection. ## Sign up for The Canada Report Subscribe Email sent!
