This is reasonably amusing: a Half-Life 2 mod project that recreates large areas of central Toronto.
The website explains:
City 7: Toronto Conflict, is an action packed Half-Life 2 mod with a variety of unique levels and game play. Explore what has become of City 7 in areas like Dundas square, Eaton Center , Mel Lastman square, St. Michael's Hospital and TTC system under the Combine rule. This version features Gordon Freeman as the main character, stuck in Toronto due to a teleporting accident in Kleiner's lab. Try to escape this war torn city by finding any type of teleporting technology and send him back to City 17.
