Nothing moves on weekends in Canada. Regular mail sorting happens on Saturdays, but nothing (except priority/express/overnight stuff) actually goes anywhere. If one were to send a regular letter from (for example) London, Ont. to Bayfield, Ont (about a 40 minute drive?) the letter would go from mailbox, to London's "sorting offices", to Windsor's "sorting offices", to T.O.'s offices, back to London (I am not making this up! This is actually how much in-province mail is routed!) and then finally off to Bayfield. Assuming the letter is lucky and ends up on the top of every pile along the way (or for some reason skips Windsor), it's going to spend 4 days being sorted. Canada Post is TREMENDOUSLY slow!
