I've read up on what you can bring into Canada and back into the USA.Simple question - what about the on-water in the tanks? Do I need to dump all the Canadian water before returning into the USA? Do I need to dump all the 'Merican water before entering Canada?

If I fill the black tank in Canada I'll leave it in Canada. I'm of the opinion what flushes in Canada stays in Canada.

I have never heard of anyone that has any problem with water.

A good question. They do not check the tanks.Watch your produce though. I had all my American tomatoes fresh from my parents garden confiscated upon returning to the USA from a short Canada trip. Lol

Crossing into Canada & back - what about on-board water?

They gave up on trying to enforce that a few years back......

It was becoming too much of a problem trying to keep the US & Canadian water separate in the Great Lakes, especially in the winter.......

You will have to convert your on board water from gallons to Litres in order to cross the border.
