It might be “just business”, but I found it odd that Trump said he does not like Conservative leader Pierre Poilievre and much preferred Carney.

Then there is the Alberta factor I mentioned.
Canada is very rich in resources, but because they have basically handicapped themselves. They are not using them effectively; that is the main reason they are so dependant on the USA.

Poilievre, recognizes this and wants to make Canada more self sufficient.
