The Presidents' Conference Committee Car was a streetcar used by the Toronto Transportation Commission and the Toronto Transit Commission. The PCC streetcar was designed by the Presidents' Conference Committee, a group of transit operators in the United States and Canada. The TTC version was built in Montreal, Quebec by Canadian Car & Foundry under license from the St. Louis Car Company of St. Louis, Missouri.

Of the 745 PCC streetcars the TTC owned—the largest fleet in North America—only two remain in operation. Cars 4500 and 4549 display their original 1951 fleet numbers, although renumbered 4604 and 4605 for record-keeping purposes after rebuilding in 1989. Classified A-15H (for Historic), the two cars are retained for charter service, although they often operate on summer Sundays on the 509 Harbourfront route.

Most of the PCC streetcars owned by the TTC were purchased new, although 225 were purchased secondhand from other transit companies as their PCC fleets were withdrawn from service. Many of the TTC's retired PCC cars were purchased by other organizations.

After their retirement, several of the TTC's PCCs were sold for different purposes.
