In Canada, hockey is a little bit weird culturally. It's very much still a rich (or at least middle class) white sport, primarily due to costs of equipment and rink time. It's also culturally the Canadian equivalent of the NFL, in that it exists nearly everywhere in Canada, and in fact most players tend to be from large cities or their suburbs, but it's coded slightly culturally conservative and associated with small towns. That being said, every lib I know is into hockey. It's whiter than NBA fandom, and I think Canadians of color would more likely be a raptors fan than fan of any Canadian hockey team, but it's still the national sport and largely crosses identity lines.

Edit: its worth noting that even the conservative friends I have into hockey are very much the American equivalent of Democrats... They're really Liberals by Canadian standards too, they just grew up in a culturally conservative area and consider liberalism to be some weird thing arrogant torontonians are into. Generally they're believers in a milti-ethnic canada, support lgbt rights, etc etc. But also the giant sampling bias I have is that the overwhelming majority of my social circle is millenial and younger. Older hockey fans are probably shitheads.
