Your question is not clear.
Here I assume that you have maple card, but you only stay in Canada for a short time. Other time you have stay in China.
Base on the assumption, the answer is --
Your Maple card already been invalid if you did not stay in Canada for 2 years in the past 5 year. You will be denied entering Canada at the border.
