Before heading west, make sure you have all the facts!
Good points:-
Canada is a great country to live in, and probably a much better place to raise kids than the UK.
The money goes a long way here.
Canadians are, for the most part, much more friendly and helpful than most Brits, and that goes for businesses and even some governmental office types as well as neighbours and service-industry people.
Controllers seem to have more fun at work than in the UK.
Bad points:-
Training, especially in Edmonton ACC.
The seniority system - you will be at the bottom of the leave roster for years.
Leave entitlement sucks.
Having to "earn" sick leave.
Procedural control is a reality here, and in even in the terminal environment there's more procedural separation applied (mainly with trainers doing approaches to satellite airfields) than you might expect.
Edmonton ACC has the worst reputation among the centres for morale and training, followed by Winnipeg. My advice is to go to either Toronto or Moncton Centre (at the latter, you'll get a HUGE house for decent money) or to go to a tower where, in general, they seem to have more fun despite less money.
