Natural Resources Canada (NRC) stated that it's premature to determine the reliability of electric vehicles (EVs) in Canadian winters. Despite six years and $76.1 million spent on studies, inconclusive results were obtained. NRC-funded research focused on winter charging stations in Yukon, electric buses in Brampton, ON, and other projects. The report highlighted technical and non-technical barriers, including cold weather affecting charging efficiency. Auto testers found that temperatures as mild as -8°C could drain EV batteries and reduce performance by up to 50%, especially during short trips with frequent stops. The report warned of potential negative outcomes from the government's EV mandate, which aims to ban new gas and diesel vehicle sales by 2035. Concerns include disruptions to electrical grids, environmental impact from battery component mining, and carbon emissions from EV production. Defence Research and Development Canada previously labeled zero-emission vehicles as unreliable in Canadian winters. The Parliamentary Budget Office estimated EV subsidies to cost up to $50 billion, three times the annual production value of the entire Canadian automobile industry, with potential increases due to debt financing.
