At the risk of being downvoted, I think the beer quality is pretty similar on both sides of the border, except in what we call the Pacific Northwest, in a greater sense - Cascadia, if you will.
I’m not saying good beer doesn’t exist other places, but in my book, British Columbia, Washington and Oregon form a sort of fantastic microbrew continuum, an example where regional culture transcends the national borders.
A beer from Vancouver or Victoria is comparable in quality to Seattle or Portland, but they collectively wallop most breweries in the other parts of both our countries. These places have a much more developed beer culture, too. Hanging out at microbreweries is so much more of a thing in that region.
