I'm a Brit living in Quebec.
Married DH who is French Canadian. Moved over here in 2009. DS was born here, in 2013.
For me the pros of living here are :
Nearly free daycare - $7 a day - not sure if this exists in NS.
Four definite seasons - gorgeous summers, very cold winters. I don't mind the cold.
People are less aggressive, easier to make friends, very open.
Less crime.
Cheaper - we have a four-bed detached house and huge garden - would never afford that in the UK.
Great food in restaurants, very affordable too.
Great outdoors - canoeing, hiking, skiing, very accessible etc.
Cons:
French language (not a problem in NS)
Far from family (mine all in UK)
Nothing like National Trust etc, days out.
Healthcare system isn't great - not sure about NS.
Huge distance between places. Wine is more expensive. Flights are more expensive.
Can be a bit insular - a bit small town mentality. And bear in mind Canada is probably ten years behind UK fro lots fo stuff i.e. Just waking up to certain issues.
