Canada is bigger, way more diverse, has way more population, and is structurally, historically, and culturally similar to the US.
And speaking as someone who has lived or worked in a couple of those countries: it ain't all rainbows and cupcakes.
Denmark ain't exactly crazy about foreigners, plus there was just an article here about how ruthless they are with data surveillance. There isn't a huge market, jobs are tight, and "tall poppy syndrome" is a thing -- which is a problem for the HN wannabe-tech-mogul crowd. They're not the most open people -- kind, nice, polite -- but also closed off; its not easy to make friends. They're not crazy about immigrants, and there is very much a "for us, by us" mentality; high immigration in Sweden is, like in much of Europe, not popular with large segments of the population.
Outside of some cultural artifacts like Rugbrod or the Copenhagen obsession with fermenting every kind of food, there isn't much you can't get in Canada. Slightly less fat, slightly better dressed, and the English was often better.
