that is what I heard before. But it is not as simple as this.
1: First, you need to identify your "residency status".
(Revenue Canada official site:
http://www.ccra-adrc.gc.ca/menu-e.html)
a: resident, who lives and works in canada
b: non-resident, who lives and works outside of canada and doesn't have "ties" in canada
c: deemed resident, who lives and works outside of canada but have "ties" in canada
d: deemed non-resident, who lives andworks outside of canada, have ties in canada, but the country where he works and lives is under the term of "tax treaty" with canada (US is one of them).
therefore, you shall be considered as a "deemed non-resident" if you can prove you have ties in US as well (for example, a driver license).
2: if you are a "deemed non-resident", prepare your tax report as "non-resident".
Please visit
http://www.ccra-adrc.gc.ca/E/pub/tp/it221r3-consolid/README.html to determine your residency status first. You should send a letter to Revenue Canada to get a confirmation for your best if you prepare the tax on your own.
I still suggest you find an agent to fill the tax report for the first year. that would be helpful.
