How do I obtain a Canadian police record check approved by the Chinese Embassy in Canada?

I am applying for a long-term residence permit in China, and one of the documents required is a certificate attesting that I have not committed crimes in Canada. This certificate needs to be issued/approved by the Chinese Embassy in Canada.

When I came to China 9 years ago, I obtained such a certificate from my local police service before I left How do I do this now that I'm living in China? And how do I have it approved by the Chinese Embassy in Canada?

Thanks,
