This year's Doors Open theme is Hidden Histories and we're looking forward to welcoming visitors and connecting them with Toronto's railway past at the John Street Roundhouse.

Activities run on May 25th and 26th, from 10:00 am to 5:00 pm and admission is free for the entire weekend!

Visitors can expect guided tours, a model train show, park animations, and the return of the Miniature Train (weather permitting). The museum store located in Don Station will also be open during the event.
