Hello
In responce to building time in Canada, i would have to say it is much better than in the states. Canadian time is much more respected worldwide than much of the US time. We have US pilots comming up here all the time and turning back when they find out that they are no longer under "radar coverage".
We deal with extream heat, to extream cold, deal with icing and vapor lock, you really learn how to be a pilot in command since traveling to many airports up north, you are the only one there.
A 172 can be rented for 105/hr canadian, i think thats roughly 35 Pounds
I really do reccomend flying in Canada, its a massive country, everyone is friendly, A/C are cheap and the maintenance on most of them is incredible... more importantly, it will make a great pilot out of you !
Good luck !
