I guess since you are canadians, all your legal issues as divorce, inheritance, etc. will stay under Canadian legal regulations. Qatar has nothing to do with that. You are not Qatari national. If you want to divorce, you have to do it through Canadian lawyer, not in the Qatari court. Even if you wish, you cannot get divorced in Qatar. You have to do it in Canada.
Driving is bad. Very bad. Extremely bad... specially after driving in canada.
Be also prepared to “culture shock” and “a sudden move to Doha” very possible could be "too much" of a change for your wife... But can you “move NOT suddenly”?? ..lol...And on the other hand, I think you are aware about muslim traditions and culture. I am sure your parents raised you in a traditional manner as much as it’s possible in Canada. So you will be all right. There are buddies here from all around the world, a lot of them never even heard arabic language before coming to Doha, never really knew about any muslim traditions... And they are doing fine.. some of them r learning arabic, and we are all learning a lot about muslim culture and traditions...So welcome to Doha and enjoy your life here. And as I always say: If one day I get really sick and tired of all that, I can just pack up my stuff and go back home...I've got one, Hamdullillah!
