(Also note that in Quebec provence flying a Canadian flag can be a bit of a political statement… it seemed easier to me to be carefully neutral on such things).
I would say likely Ontario, and specifically the Ottawa capital region. Though, since the Convoy, waving a Canadian Flag has taken on a Conservative/right wing/populist connotation that I think is still around today, so it may be shifting in the direction of Alberta and Saskatchewan.
