Enhancing the Resilience of Manitoba’s Winter Roads System

This case study examines the socioeconomic importance of Manitoba's winter road network and the provincial government's efforts to enhance its resilience in response to climate change. It details how warming winters have shortened the operational window of these roads, leading to increased costs and safety risks, and describes the subsequent policy and funding interventions used to adapt the system.

• Winter roads are critical for 28 remote communities in northern Manitoba, where approximately 30,000 people live in an area of 560,000 square kilometres. These roads, totaling 2,178 kilometres, are typically viable for about eight weeks from mid-January to mid-March. They provide a cost-effective alternative to air transport—reducing costs by two to three times—and support essential services, social networks, and employment in a region where unemployment rates can reach 80 to 90 per cent.
• Climate change has reduced the reliability and safety of Manitoba's winter roads. The number of usable days per year dropped from an average of 50 or 55 days to as low as 20 days in 1999/2000. In 1998, a warm winter prevented the construction of roads to 12 communities, forcing the air transport of one million kilograms of food and 10 million litres of fuel at a cost of $15 million to $18 million to the Canadian and Manitoba governments.
• Research conducted by the University of Winnipeg, in partnership with the Prairie Adaptation Research Collaborative (PARC), projected that warming winters would continue to shorten the winter road season. The projections estimated reductions of approximately 5 days in the 2020s, 10 days in the 2050s, and 14 days in the 2080s.
• The Government of Manitoba increased funding for the winter road network to improve adaptive capacity, with funding tripling since 1998 and reaching an annual average of $13 million between 2007 and 2011. Investments focused on upgrading existing roads, constructing new overland routes, and relocating roads away from water bodies to improve safety and extend the operational season.
