In order to keep your PR status, you must live in Canada for 2 out of every 5 rolling years. Since you have been outside of Canada for 3 years, you now need to remain in Canada for 2 years straight to be certain you can keep your PR status. It doesn’t matter when your PR card was renewed. The PR obligation is a rolling obligation. So yes - if you leave now for another three years - you could very well put your PR status in jeopardy.
