Mayor John Tory and Prime Minister Justin Trudeau, who were also introduced to the stage were widely cheered by the crowd.

The incident comes after two other recent public appearances where the premier was booed.
One at a Special Olympics Ontario event in May and the other later that month at the Collision technology conference, both in Toronto.
In an interview with Global News following the Special Olympics event and Collision conference incidents Premier Ford said “these are the same people that have their hands in the public trough that have been getting money from the public, hard-working people, in the back of factories, in the offices, small business owners.”
The less than warm reception comes as the Premier has faced dismal public approval polling numbers.
It also comes days after the Premier celebrated one year since being elected. The premier’s office declined comment on the crowd’s reception of Ford at Nathan Phillips Square when reached Monday by Global News.
