There is now a way to get to places that can only be reached by air at other times of year. Ice roads have opened for the season in northern Ontario, linking remote communities to each other by land.
Bitter cold -- such as recent temperatures below -30°C or -40°C before the wind chill -- make it possible to have roads on frozen lakes.
In northwestern Ontario, some ice roads linking First Nations recently reopened to light vehicle traffic. However, heavy supply transport and fuel trucks haven't been permitted.
People in remote communities in Ontario's north rely on ice roads to deliver supplies that would be costly to import by air.
