A 4.3-kilometre stretch of the Rideau Canal will be open for skating Thursday morning, the National Capital Commission announced Wednesday.

The ice between the National Arts Centre and Bank Street will open at 8 a.m. to begin the 40th season of skating on the canal.

An official opening ceremony will be held near the Canal Ritz Terrace at 10 a.m.

Maintenance crews started clearing snow and flooding the ice surface on a 4.3-kilometre stretch between the National Arts Centre and the Bank Street Bridge last Friday and Saturday nights as temperatures dipped to below - 10 C.

The ice must be at least 30 centimetres thick before it's safe to open the canal, the NCC said.

Last year, almost all of the 7.8-kilometre skateway was open by Jan. 9.

There is freezing drizzle in Environment Canada's forcast for Wednesday night and Thursday. However, the temperature is expected to drop to - 10 C overnight, and rise to - 1 C on Thursday.
