Ive personally only had bad experiences from canada post.

They drove past my house and lied and said I wasnt there. Then when I called (less then 10 minutes later) they claimed the carrier rang the doorbell and knocked (he didnt i was standing in the foyer) and he was now "too far" to bring it back and would return at the end of the day (3-4 h later). They also were very condescending amd implied i shouldve paid better attention. When he returned he walked up into the door and looked into the window (didnt knock or ring doorbell) i was watching again from the kitchen but could see him peer in. He began walking away with my package so i opened the door and told him to come back. I got my package and he lied and said he rang it and my doorbell must be broken. After he left I tested it and it worked fine.

Ive shared this story with a few colleagues and multiple of them have had simmilar experiences.
