yeah, if you're going to import back to canada, you'll have to get an out of province inspection done and you will have to have the DRL's installed - all within 45 days of crossing the border if i'm not mistaken. the module might already be installed on the car and just need to be 'turned on' so to speak, or you may need to pick it up and have it installed, i don't know.
the car will also have to meet all federal AND provincial safety standards so make sure you check both out because they can be different. if you haven't already done so, i highly recommend calling the Registrar of Imported Vehicles and talking to someone about what you will need to know/have done to the car to legally import it into canada (this is federal only); once you've done that, contact the traffic safety department of whatever province you're going to be moving to and find out what their regulations are. you will also need to notify the EXACT border crossing where you plan to go through and find out what information they need in order to import your car (this is the US and the Canadian border agents at that location). i do know that the US location requires certain paperwork be sent to them 72 hours in advance of you crossing; if you don't give them the advanced notice they WILL hold your car for 72 hours to verify the paperwork.
as long as you check into things, and double check to make sure you're getting the right information, it's not a difficult process - just do your homework.
