Thanks for the link!
I may be reading this incorrectly, but with the staggered closing times in different time zones, every poll in Alberta, Saskatchewan, Manitoba, Ontario, and all but one in Quebec will close at the same moment (9:30 EDT). That's going to make for a hectic few minutes of election-watching!
Navanut and NWT too, and every riding in Quebec I think, as the portions of PQ that are in Atlantic Time don't use daylight savings time, so are effectively in Eastern Time right now (although they included Gaspésie–Les Îles-de-la-Madeleine on that list and not Manicouagan, so perhaps the Madeline Iles use Atlantic Daylight Time like nearby PEI, but the portion of that riding on the Gaspé Peninsula (which has a majority of that riding's population) would not finish voting until 9:30 EDT and so any exit polls for that riding would come in at the same time as the rest of the Quebec ridings, even if part of that riding stopped voting an hour earlier).
