Oh, I should add that, although their reference to "Oakridge" undoubtedly refers to the real place, their scene-setting exterior shot was actually filmed elsewhere.

The same thing happened with St Patrick's Station (in "The Black Buddha, Part Two"). That is the name of a real subway station on the University Line, located downtown at Dundas and University—and thus quite appropriate for the story. However, for filming, they actually used a completely different location.

A matter of practicality, no doubt. Money, permits, etc.
