People in Toronto will have the chance to view jaw-dropping vintage streetcars alongside the rare opportunity to tour a TTC facility this weekend.

Marking the 100th anniversary of the Hillcrest Complex, the TTC is giving riders from across the city the chance to dive into the history of the organization, both by learning more about how it operates and by getting up-close and personal with pieces of the transit agency's history at a rare open house.

From 11 a.m. to 4 p.m. on Saturday, Sept. 28, you'll be able to dive into the past 100 years of transit history in Toronto by exploring current and vintage TTC vehicles, such as streetcars and buses and viewing various photos from the past 100 years of the TTC Hillcrest Complex.

First opened in March of 1924, the facility remains the largest complex in the TTC's fleet, and is the location where the majority of maintenance, repairs and refurbishments to TTC vehicles are done.

History buffs may also be interested to learn that the facility was used to manufacture military equipment parts during World War II.

In honour of the anniversary, you'll also be able to go on rare behind-the-scenes tours of the complex, getting a first-hand view of the place that keeps the city's all-important public transit system in tip-top shape.

The event is open to all, but you'll have to make a $5 donation to enter, with all proceeds going to United Way Greater Toronto. Children two and under get in for free.

It's all going down at the TTC Hillcrest Complex, located at 1138 Bathurst St., and the TTC will also be running shuttle buses between the event and Bathurst Station for the open house's duration.
