My family and I vacationed in Canada probably 7- 8 times when the kids were small--non air-conditioned pop up camper made trips to the North better than ones to the south!
Ontario is like you describe--like Michigan-North; same language, same stores ( more or less) same-same.
We visited Quebec at the height of the separatist movement, very different, Much more like being in a foreign country. Merchants greeted in French first, but immediately switched to English, if the customer desired--some private citizens were less easy-going. However, they were generally more accommodating to English-speaking foreigners (us!), than English-speaking Canadians. We even took our "Parisian-French" exchange student on one trip, and he ( in typical French fashion) was rather dismissive of the language as spoken there.
New Brunswick and Nova Scotia were even kinder and gentler. A pedestrian only has to LOOK like they might want to cross the street and traffic STOPS and waits, patiently.
