Under normal circumstances, the city closes multiple rinks in late February, while select rinks remain open until March.
Which rinks are closed early is based on how many people use them, whether a safe level of ice cover can be maintained and budgetary restrictions.
Mayor John Tory is reaching out to the private sector "to see if we can get additional support to keep these rinks open through this cold snap," according to spokeswoman Amanda Galbraith.
Last year, the city relied on donations from corporate sponsors to keep 11 additional rinks open over the March break.
"The Mayor believes we should keep our outdoor rinks open so Toronto residents can enjoy this time honoured tradition," said Galbraith.
Here is a list of rinks set to close on Feb. 22:
