Will Smith and Margot Robbie, along with director David Ayer, promoted the movie during a red carpet event in the Distillery District, a portion of which is being transformed into a setting like the Belle Reve Penitentiary.
Along with sets and props from the production, fans will also be able to don a "safety suit" costume and take part in character Harley Quinn's "Smash Room."
Belle Reve is the prison facility depicted in DC's Suicide Squad comics and in the upcoming film, slated to hit theatres in Canada on Aug. 5.
The ensemble film — about a team of supervillains enlisted as reluctant heroes for a special mission — stars Smith, Robbie, Jared Leto, Joel Kinnaman, Viola Davis and Canadian Adam Beach.
Warner Bros., the movie studio behind the anticipated antihero tale, wanted to offer something "special" for Toronto.
The Belle Reve Penitentiary Fan Experience will be open to the public in the Distillery on Wednesday and Thursday, 1-10 p.m. local time. Admittance is free.
