I don't know how you choose Qatar as one of the places that's on top of your list to go. You have Canada degree and Canadian citizenship, sure you have lots of good choice like Australia, New Zealand, Singapore and others..... Heading to any Gulf Countries (including Qatar) means selling your freedom no matter how much they pay you... I know they pay according to passport even for same position, so you will get higher ofcourse than that of Pakistani or Indian. Anyway best of luck and share your experience.
