I'm in the exact same sandbox, left Canada 2 yrs ago.
I couldn't care less about my canadian licences/medical, except if I want to take my kids up for a one hr joy ride in a 172.
There are no jobs at all worth considering in Canada if you're already in the middle east, I'm sure for my lifetime it will always be that way.
Canada is a good place to start a career as a pilot, bad place to try to finish it, unless your daddy was an AC capt.
