the form is NR 73 and NO you do not HAVE to fill it out. I never did. When you file your 2007 taxes with revenue canada, there is a spot on the first page that ask the date you became or CEASED to be a Cdn resident. put the date in when you entered the USA!! Some have filled out the NR 73, some don't. My attitude is if they wanted it, they would contact me and tel lme to fill it out. Why fil out more paperwork if you do not have to!!
Time for me to chime in as I always do on this topic, hey flames??

When I went to file my 2005 Canadian taxes (through a Canadian CPA firm that I had dealt with for years), they weren't allowed to file my taxes until I had filled out said form. So I did. And got my tax refund, and a separate letter stating that in Revenue Canada's eyes, I am no longer a Canadian resident. I didn't have a clue about this form, just heard about it when the CPA called me.
