Canada's (third-)world-class postal system

Sending a package from Chicago to Hamilton via Priority Mail seems to be the kiss of death, judging from Canada Post's performance. Today I finally received something sent in this way from the Windy City on tuesday, 14 March — two weeks ago tomorrow! Imagine if it had been sent by conventional mail. It might have been months. This is not the first time either. If I lodge a complaint from my end, I am told that only the sender can do this. But if the sender does so, the US Postal Service employee tells him it will do no good. The complaint will drop into an abyss on this side of the border and never see the light of day. It seems I'm not the only one to experience frustrations with Canada Post. This country deserves better.
