If you were working in Canada and then left, you must file a T1 for the year that you left, and you must declare on your T1 that you are no longer resident with the date that you left.
Canada has about the toughest residency rules for tax in the world because they don't want people to move to the US.
If you have any residential tie to Canada, such as a driver's licence, OHIP card, etc. (basically anything only a resident could get), caselaw is that you are resident for tax purposes and must pay tax in Canada.
You can have a house (although that's very tricky if you've just left, especially if it's not rented out) and you can have a bank account, providing you've declared your non-resident status to the bank so they can withhold Part XIII non-resident tax.
In addition, you can be assessed the exit tax, which is basically a capital gains tax on your assets if you lived in Canada for at least 5 years before leaving. Generally speaking most people only get hit with this if they sold their house and realised a profit on it, or have other significant investments that have increased in value.
Check the CRA non-resident website.
My personal advice is to sever all residential ties as fast as possible when you leave (unless for immigration purposes this is difficult, say you are on some sort of visitor's visa or work permit that requires proof of residency abroad). Change your DL, etc. ASAP.
The key is "residential tie". Being physically present in Canada for 90 days in a year is also a residential tie, although there are legal ways around that one by claiming a tax home abroad via a tax treaty.
The court case the CRA and every accountant will quote you is the one where some guy moved to Dubai and put his household effects in storage. He still had a valid Ontario DL and was deemed by the CRA to be resident in Canada for tax purposes, as he had "residential ties". This was upheld on appeal.
Usually where it gets sticky is where people forget to tell the CRA that they have left, what happens then is the CRA wants to know why you haven't filed a T1. Best case scenario you're looking at a late filing fee for the year that you left.
Worst case scenario you lived somewhere with no income tax, the CRA deems you resident all the years you were there, and you have to pay income tax in Canada for all those years because you had some ties to Canada still that you forgot about (valid DL, forgot to tell the bank you were overseas and they filed a T5 every year with the CRA). Plus penalties for late payment.
If for some reason you cannot sever residential ties, make sure you claim the tax treaty exemption so you only pay tax in Canada. Otherwise you could face dual taxation.
