AT,
I came to the UK in the last year and have done very well. I have similar time to you and was left seat in a much bigger faster machine here than in Canada. I am now going on a Boeing. Just got the licence and the jobs were there. I was not forced to pay for a rating as some would have you believe. If you have 3000-4000 hours of JET A time you will get noticed and by more than one operator.
Although I miss home my career has rocketed over in Europe and I will return when I am ready.........Semi retirement!!!
Good Luck.
