It may be summer '16 in Toronto, but it won't feel that way on Queens Quay. That's because the TTC is bringing its vintage PCC streetcars back to the 509 Harbourfront route every Sunday from May 22 until Labour Day weekend.

This piece of Toronto history will be free to ride, which really ups the ante if you're looking to travel from Union Station to somewhere near the Fleet Street loop (i.e. Exhibition Place or the Amphitheatre).

If you can't catch a PCC on the 509 route, you can always rent one out. You can charter these streetcars, which date back to 1951, for a cool $1,881.45.

Starting this Sunday, and every Sunday this summer, ride the PCC streetcar on the 509 Harbourfront - fare-free! #TTC pic.twitter.com/hOBnyeYqpK â Brad Ross (@bradTTC) May 18, 2016
