Canada

We'd take a hit for sure. 0 km shipping distance is just a really good deal, even before you build infrastructure. I think I've heard it put at 3% permanent GDP loss, which is about the same as being a couple years of growth behind.

I'd advise you to consider what staying with the US could do to us, and how many of your fellow Lemmings might end up in El Salvador. There isn't really a sacrifice-free option.

All these costs and we then have to compete with countries on that continent who can build pipelines to Europe.

So more or less Russia and Norway. Norway is at capacity last I checked. Russia is obviously not an option. They're importing from the US and places like the Gulf countries right now to keep the lights on.

Maybe if we are so economically dependent on a finite substance that damages every part of the planet it touches, we should think of changing the priorities of our economy. Quebec is great at producing energy with its hydroelectric plants generating about 1/3 of all electricity generated in Canada. Quebec is also decent at saving energy being only the 8th largest energy use per capita of the provinces.

It is just wrong to claim Quebec imports all its energy from the US when Quebec actually exports a lot of electricity to the US while importing fossil fuels. Quebec could be far more energy independent if it focused on electrifying more stuff, the opposite is true for fossil fuels in Quebec.
