After four decades of shuttling Torontonians across the downtown core, the TTC’s Canadian Light Rail Vehicle (CLRV) streetcars, characterized by their plain, old-timey exteriors, will make their last run on Dec. 29.

From 10 a.m. to 2 p.m. that day, two CLRVs will run for free between Bathurst Street and Greenwood Avenue “to commemorate the final day of service,” the TTC said in a news release.

To land a spot on the official “final ride,” Torontonians must sign up for the TTC’s contest on Facebook or Instagram.

The TTC was encouraging anyone interested in registering to “stay tuned” Friday morning.

The 20 lucky winners (10 from Instagram, 10 from Facebook) get two seats on the final ride: one for them and one for a friend. The winners get to journey down memory lane, from Wolseley Loop at Bathurst Street to Russell Carhouse at Greenwood Avenue.

TTC spokesperson Hayley Waldman told the Star that the “Canadian Light Rail Vehicles are iconic pieces of Toronto present and past,” and that there are lots of streetcar enthusiasts — and nostalgic commuters — who will miss the old model.

All the same, Waldman says, the TTC is “excited to take the opportunity to celebrate this last ride with our fellow streetcar lovers.”
