Doors open Toronto takes place the last Saturday and Sunday of May every year.
This event takes place all across Toronto and is free of charge other then your transportation cost and in some cases parking fees will apply. There are approximately 150 buildings open to the public. Several buildings participate yearly in this event while others come and go depending on the theme for the current year. Each year at the beginning of May a new list of buildings is posted on the doors open Toronto website. 2018 was themed around the theatre and the movie making industry in Toronto, everything from sound stages, lighting and camera corporations, production facilities, costume designers and rental agencies were all participating.
Many heritage sites including churches, theatres, and government buildings open parts or all of there buildings to the public with some providing guided tours explaining history and architectural features the public may never have seen or known about. This event only happens one weekend each year rain or shine and it is a great way to learn about the city of toronto and its history
