I live in Alberta so I can’t say much on the front of where to live.
When a lot of Canadians say they hate the US (including myself) we are more so saying that we hate the government, not everyone living there. I fully welcome any Americans who want to come to Canada with open arms to escape what is going on down south and I highly doubt you will face much bias being from the US.
As for businesses, I have started to use co-op a lot more especially for gas. I don’t know how many there are in BC, but we have them everywhere here in Alberta. It’s a Canadian co-operative association and you can get a membership to your local co-op for $5 CAD (it isn’t required to shop there but you do get equity and money back on every purchase you make)
I was specifically talking about https://co-op.crs/, a chain of cooperative grocery stores and gas stations through western Canada. However, that seems to be a good list of other coops worth taking a look at!
