How bad is the USPS?

I find that VERY hard to believe...It takes a month to get Anything up here to Manitoba Canada...I will not and never again use USPS...I will pay anybody UPS Fedex,I cannot afford the wait times that come with USPS.
I'm sure that they are cheap and efficient for the people in the US,but when it comes to coming up here...I stay away!

Customs is more than likely the cause
