Toronto's Pride organizers say Justin Trudeau will become the first prime minister to participate in the festivities.

Trudeau is expected to march in the parade on July 3.

The city's first-ever Pride Month launches June 1 with a theme of belonging and inclusion.

Along with Trudeau, Finance Minister Bill Morneau, Ontario Premier Kathleen Wynne and Toronto Mayor John Tory are also slated to take part in the festivities.

Organizers have said gay Syrian refugees will have a place at the Pride events.
