How long before I lose my Canadian PR?

[1389]

I obtained a Canadian PR visa valid from Aug 8 2006 to Dec 20 2006. I landed on November 23 2006 but only stayed until Nov 27 2006. I never applied for PR card and I haven’t been back to Canada since. I understand I have to spend at least 2 out of 5 years in Canada in order to not loose my PR.
Does anybody know when the 5 years starts counting: the day PR was approved, the day I landed or some other day?

I appreciate any advice.

The day you landed as a PR of Canada.
