Things to do in Toronto this weekend include the return of Doors Open Toronto, the grand-opening of the Bentway's new summer art exhibition (which includes an enormous sand dune in the middle of downtown Toronto), and the Inside Out Toronto 2SLGBTQ+ Film Festival. If those don't tickle your fancy, you can also celebrate the kickoff of Fashion Art Toronto's 20th year with a huge public party and fashion show, or attend a totally T-Rexiffic dinosaur-themed party at the ROM.
