TORONTO – Ontario’s premier and two federal political party leaders will help kick off Toronto’s 33rd annual Pride Parade in Toronto today.

Premier Kathleen Wynne, NDP Leader Thomas Mulcair and Liberal Leader Justin Trudeau will attend a church service before the parade.

Wynne, who is Ontario’s first openly gay premier, will also become the province’s first sitting premier to take part in the Toronto parade.

The outdoor church service is expected to see hundreds of community members turn out to show support for the gay and lesbian community.

New Democrat MPs Craig Scott and Olivia Chow will also be on hand, before joining Mulcair and other Toronto-area politicians on the NDP float in the parade.

Wynne and Trudeau will also march in the parade, which is expected to see thousands fill the city’s downtown core for what has traditionally been the largest event of its kind in the country.

The church event will also see performances by musician Alana Bridgewater, along with Danielle Wade and Jamie McKnight of the Wizard of Oz musical.
