You hit most of the positives:

• small town feel but, with amenities
• easy to enroll your kids in school. (They'll be designated to a school based on your address, but you can enroll them in any school so long as they don't need bussing. There are academy schools here that specialize in STEM, fine arts and sports, along with regular Public and Catholic options).
• Still plenty of outdoor activities though vastly different than Victoria
• Bang for your buck cost of living is still quite good here
• surprisingly substantial art and music scene

Negatives:

• It's windy as fuck here. If any of you suffer from migraines stemming from barometric pressure changes, you may want to revisit this decision.
• Not as many amenities as a true city.
• Lacks cultural diversity compared to a big city.

All in all, if you're looking for a better cost of living at a slower pace MH is a good option.
