All and all, it sounds like a good application. The problem is mainly having a wife in Canada. It's nothing about you or him. It's people who lied in the past -they ruin visiting for many people.
If you're married, he could ask for a work permit if you're studying. I'm not as familiar with this process, so I can't give you the best advice but it seems this works more often. He is not required to find work. He can visit. The permit would be valid as long as your study permit. I believe he can leave Canada and return (for another visit or to find work if he decides) BUT I'm not sure! A lot of people recommend the work permit for students. Plus, if you decide you cannot bear to be apart, he would be allowed to stay in Canada and work. (Salaries are generally lower than the UAE, but what is money when you have love? Hehe!)
I would suggest going to International Students section and look for SPOUSE OWP, spousal OWP, or open work permit threads. Or just make a new one!
The experts there will give you advice much better than me.
