Thanks everyone for the replies, I think that pretty much covers everything. I'm about to do some differences training at Fife on the C172, as yes it's common as muck and you can find them anywhere. Ironically enough I did all my training at Cumbernauld on Katanas and I don't think they're in short supply there as one of the Diamond Factories is over there.
Just need to make a few calls/send a few emails to sort it all out, and of course study the half mil Toronto VFR chart.
As far as RT is concerned, I'm surprised they're so relaxed. And flying round the CN tower??? Try that in the Big Apple!
Think I'll stick to the way I've been trained with RT with the expception of the abbreviated call signs.
Cheers folks.
