The Canadian Light Rail Vehicle (CLRV) is a streetcar used by the Toronto Transit Commission (TTC). They have been the prevalent on the Toronto streetcar system since the late 20th century. It comprises two variants: the standard, single-module CLRV and the longer, articulated, double-module Articulated Light Rail Vehicle (ALRV).

As of 2016, CLRVs are used on all streetcar routes except 502 Downtowner, 503 Kingston Road, 510 Spadina and 511 Bathurst and comprise the entirety of the fleet on most routes. The ALRVs are used mainly on route 501 Queen but are sometimes used 504 King during peak periods.

At the end of the 1970s and the beginning of the 1980s, TTC's fleet of PCC streetcars had approached (or exceeded in some cases) the end of its useful life. Many Toronto citizens, and a group known as "Streetcars for Toronto" had fought successfully against the TTC's plans to convert its remaining streetcar lines to buses, and thus necessitated a new streetcar to replace the aging PCCs. The "Canadian Light Rail Vehicle" was an attempt at a new, standardized streetcar design to be used in Toronto and in other new streetcar developments throughout the country. There was also a similar attempt of the concept made in the United States around the same time, with cars built by Boeing Vertol for Boston's Massachusetts Bay Transportation Authority and the San Francisco Municipal Railway.

The first ten CLRV cars were to be manufactured by SIG of Zurich, Switzerland, and used as prototypes for Urban Transportation Development Corporation (UTDC) (now Bombardier) to manufacture the rest at the Hawker-Siddeley Canada Ltd. Thunder Bay works. They were intended to be numbered 4000-4009; however, as a cost-saving measure this number was reduced to six, accounting for the absence of CLRVs 4006-4009. The remaining 190 UTDC cars were numbered 4010-4199.
