Chrystia Freeland, Canada's deputy prime minister, addresses crowd in Nathan Phillips Square

Thousands of people marched in downtown Toronto on Sunday to protest the Russian invasion of Ukraine.

The event, billed as "Mega March for Ukraine," began at Yonge-Dundas Square. It was organized by the Toronto branch of the Ukrainian Canadian Congress.

Demonstrators marched west on Dundas Street West, then south on Bay Street to Nathan Phillips Square. Speakers are addressing thousands of people who have gathered in the square.

Chrystia Freeland, Canada's deputy prime minister who walked at the front of the march, told the rally that Ukraine needs weapons and ammunition to fend off the Russian invasion. 

"The Ukrainians are making such a brave stand but they need weapons to fight this fight," Freeland said.

Toronto Mayor John Tory and Canadian author Margaret Atwood are also there to show support for Ukraine.

During the march, the crowd chanted: "Stand with Ukraine!"

The marchers held blue and yellow Ukrainian flags and placards denouncing Russian President Vladimir Putin. There was a marching band playing music.

Toronto police had closed Dundas Street West from Yonge Street to Bay Street, and Bay Street, from Dundas Street West from Queen Street West, but they have since reopened.
