Even as eastern Canada shivers under frigid temperatures, the National Capital Commission says Ottawa’s Rideau Canal Skateway will not open this season due to warm temperatures.

The commission says it has been both assessing and getting ready for the effects of climate change on the internationally renowned winter tourist attraction – the world’s largest outdoor skating rink – for several years.

But this is the first time the weather has prevented the 7.8-km stretch through Canada’s capital city from opening at all.

The NCC says the latest tests showed the ice surface remained unsafe to skate on and that any more efforts to change the situation were unlikely to work. It also says the warmer-than-usual temperatures, snow and rain caused the ice to be thin and porous.

On Feb. 2, the skateway had already experienced a record-setting delay in opening for the season.
