The statement issued early Thursday said moderate south winds gusting up to 50 km/h are expected to develop in Toronto this morning.
“Winds will then shift to the southwest and strengthen to up to 90 km/h in the afternoon with the passage of a cold front,” the statement reads.
The agency said wind warnings may be issued for some areas as the system approaches.
Environment Canada also said utility outages “are possible.”
According to Environment Canada, it is expected to hit 15C in Toronto on Thursday.
In a tweet Thursday, Toronto Hydro warned that strong winds can “bring down powerlines.”
“If you come across a downed line, always treat it as live and dangerous,” the tweet reads. “Stay back at least 10 metres (the length of a school bus) and report it immediately to 416-542-8000 (press 1).
Toronto Fire Chief Matthew Pegg also urged caution.
“Please be careful and vigilant as you move about the city today,” he wrote in a tweet. “Winds this strong can cause flying debris and downed power lines.”
