Non-resident - need to declare?

[pandaforever]

I became a landed PR at the start of 2011.  I stayed in Canada for 3 days afterwhich I returned to my home country because I have a job there.  I intend to stay in my home country until it's time to return to Canada to fulfill my PR obligations.  My questions are
1.  Do I need to declare myself a non-resident of Canada?  My home country does not have a tax treaty with Canada. 
2.  Since I do not have ties with Canada, what are the consequences if I do not declare myself a non-resident?

Since you are not living in Canada yet, have no property and no income in Canada, you don't have to file taxes.  You are already non-resident and never even became resident.

But if your partner and dependents are still living in Canada, you might still be a tax resident even though you live outside Canada.
