I moved to Canada from Cardiff Wales 3 years ago to finish my Commercial. I never went home. I dont work as a pilot but do have a satisfying job with an airline.
£1 GB = $2.50 approx against $1.8 US (appox). Your £ goes further in Canada
Self hire rental rates on average are:
C150 - £36/hr
C172 - £45/hr
...based on hourly rates. Block time would be a lot less so check with the schools. I think Canada is one of the best places to fly. It caters to flying floats, bush, and mountain flying or just local pleasure. Very hot summers, very cold winters. Dont let the winters put you off though, there are a lot of really cracking days in the winter to fly.
I also own a C150. I would consider renting it out for block time. I'm located 1 hour north of Toronto airport. If you're interested send me PM.
Good luck!
