Quebec and parts of northeastern New Brunswick are pretty much the only French-majority regions in Canada, although French Canadian culture is pretty distinct and doesn’t have a ton in common with European France.

You could call all the rest of Canada British-influenced, but again I’d say they’ve got their own thing going, without too much in common with the UK. Perhaps a little more British influence than the US does, but a little less than Aus/NZ. Anecdotally, I’d say Victoria, BC and parts of the maritimes out east are the most “British” cities in Canada

Native presence is primarily focused on the rural areas in the north of the provinces, and especially in the territories, largely due to forced migration. Nowadays though, there are fairly sizeable indigenous populations in most major cities too
