If I was in your situation I would be so indecisive as well lol. But I agree with Russ, you should go. So many people I know have gone to Canada and have loved it. You can go for the year and then come back to the UK get your job and experience.
Do I wann live elsewhere:
No I will always live in Ireland

I love it here. But I want to travel too.
Would you like to live in Ireland

Or visit?
