Thank you for the really helpful replies!
I am at a bit of a crossroads as my funds are relatively limited - I am 24 and I am self funding whilst working and travelling North America, my biggest fear is the cost involved converting the license when I get home to the UK (My GF wants to buy a house so my 'flying pocket money' will be enough for a few hours here and there of flying)
Do you know if I can fly G reg aircraft in the UK with a Canadian PPL? Most of the research I have done is inconclusive. If I can then I will happily keep the Canadian License current upon my return.
Again, I appreciate the help!
