The Toronto subway was the first rapid transit system in Canada when it opened a 12-station line in 1954.  It has since grown to encompass three heavy rail lines and one intermediate rail line and has the most number of stations of any system in Canada with 69.  Construction has begun on the Eglinton Crosstown Line and the Toronto-York Spadina Subway Extension, which will add 28 new stations and a total of 27.6 km of new track.  Montreal introduced the Montreal Metro in 1966 and has now become the most popular rapid transit system in the country with 1,263,800 daily riders.  The Vancouver SkyTrain, an automated guided line, was opened in January 1986 for the Expo 86 world fair and is the longest rapid transit system in Canada with a system length of 79.6 km .
