There is no one-size-fits-all answer to this question, as the answer will depend on the specific circumstances of your case. However, generally speaking, it is possible to drop off a UPS package at Canada Post.
However, there are a few things to keep in mind before doing so.
First, it is important to note that Canada Post does not accept packages that weigh more than 100 pounds. Additionally, you will need to make sure that the package is properly packed and that it is in good condition.
In other words, you will want to make sure that the package is not damaged and that the contents are all intact.
Finally, it is important to note that Canada Post does not guarantee the arrival of a UPS package. In other words, the company is not responsible for ensuring that the package arrives at its destination on time.
However, the company will try to deliver the package as soon as possible.
