Passport renewal is Visa still valid

In January 2016this year I had a 10 year Visa issued to me on my Canadian passport which was expiring in November 2016. I just had my passport renewed and I am planning a trip back to China in November 2016. Do I need to renew my VISA or is my VISA still valid? I read somewhere that my old passport had to be valid for a year after the VISA date. I need to know if I have to resubmit. thank you
