Canadian 'freezeway' could let residents skate to work

Cold temperatures persist over much of North America this week. But rather than just trying to survive the winter, one Canadian city is trying to turn it into an asset. With an average temperature of -12C (9.5F) in the heart of winter, and home to seven city-owned outdoor skating rinks, Edmonton, Alberta is no stranger to the cold. Unlike other cities in the US and Canada that have banned activities such as tobogganing because of insurance costs, Edmonton has no such laws. Now the city is considering flooding an 11km route for residents to commute through the city on skates.
 It's called the Freezeway.
