Huh, you're right - so Ontario had normal-looking ridings in 1867 but deliberately decided to switch to looooong Quebec-style ones later. Because Canada, presumably.Toronto actually used to have slightly more compact ridings, as per below:
(federal)
(provincial)
Can't really say why they changed, but Occam's razor says they got lazy and decided to just slice the city up into roughly equally populated strips of land.
