We moved to Prince Edward county Ontario 7 years ago.
no regrets at all apart from missing family, we have been back twice and usually a brother or sister has been here at least once a year, although it's not the same as being there email and cheap long distance calls help.
There is currently plenty of work around (I am in construction) although, don't expect to walk into a 'good' position straight away, unless you are very lucky, but prove yourself and progression / acceptance can be pretty quick.
I have found a small minority of longstanging 'immigrants' who class themselves as native canadian do resent 'newcomers' but these are the exception and most canadians are friendly.
cheap housing also helps together with a lot less people (we moved from south london) much clearer roads and lower speed limits, cleaner air and warm dry summers all adds up to a pretty good package.
yes the winters are colder with more snow, but everything is geared up to cope here 3ft of snow is 'light' and the roads are generally cleared early in the day and throughout the day. the air in this area is much drier in the winter than the damp we were used to in the UK
so although we will always miss aspects of the UK, for us it was the right move.
