Moving from Ontario to work in Quebec. What should I know?

Hi,

I will be moving from Ontario to Montreal, Quebec this summer and I know there is a lot of work to be done in terms of changing my drivers license, health card, etc.

My primary concern is: What should I know about getting ready to work in Quebec to assure the process is smooth? I can’t seem to find anything on this topic after Googling around so I’ve decided to “tap the collective” ;)

Thanks in advance for any replies to sources or just straight out answers!
