Just curious. I’m on the western part of the US, and sent a letter to Ontario, Canada.
How coordinated are the US & Canadian mail systems?
Is my letter going to go north, then east across Canada, or is it going to go east across the US, then north into Canada?
Does Canada treat mail from the US as international mail that goes through some central international mail center before making its way around Canada, or would it just go through the closest mail distribution center to its destination?
