Largest refineries in Canada that refine Canadian crude are in Alberta, Imperial's 191M barrels/day and Suncor's 142M barrels/day, both in Edmonton and then you can add on Fort Saskatchewan's 100M barrels/day, just outside of Edmonton. There's a west coast city that is nearly entirely dependent on Albertan crude oil & refining. Sarnia is refining an already upgraded bitumen though, so it's only getting half of the garbage. Also Line 9 goes from Sarnia to Montreal, Enbridge Mainline goes from Alberta to Sarnia.
