West Toronto Diamond

It connects the Metrolinx Weston Subdivision, which carries the GO Transit Kitchener line, UP Express and Via Rail Corridor passenger services, to the CPKC North Toronto Subdivision, which is the Canadian Pacific Kansas City's main freight line across Toronto.

In April 2008, Metrolinx bought the Weston Sub from CN Rail to allow them to expand the railway to support increased train service along the corridor.

The cost to do this separation is close to $500 million, but will be paid back in full in a matter of years as more trains are added to all lines.

[citation needed] The Grand Trunk Railway (GTR) built a station north of the diamond in 1907, named Carlton & Weston Road.

[1][2][3] Canadian Pacific (CP)'s West Toronto station was a more notable structure, on the southwest side of the diamond.
