Least like UK/US: Quebec, New Brunswick, Labrador, NWT, Yukon and Nanavut
Nova Scotia is like Scotland mostly. Cape Breton is kinda like Scotland mixed with Ireland, Still a lot of Gaelic communities up there.
Newfoundland is like Ireland/Scotland/Northern England
The border provinces like Ontario, Manitoba, Saskatchewan and British Columbia. All have UK and US elements.
Yukon, NWT, Nanavut are pretty much bare from what I have seen. Not been there myself so take that with a grain of salt.
Overall I would say Ontario, BC, Manitoba and Alberta are the most UK/US like.
I think Ontario and BC being the most similar.
Clue is in the provincial flag pretty much
