I would like to have a Statement in Lieu of Certificate of Non-Impediment where should I get it?Thnx

I think you mean the single status certificate, am I right? You can go to your lcoal foreign affairs office to make an enquiry.

Actually, I have a single status certificate.
I just need to know where can I get a Form of the Statement in Lieu of Certificate of Non-Impediment? In order to go to China to get married.

You can get it from the local foreign affairs office or the City Clerk's Office. I'm afraid you also have to have it notarized by your local Notary Public and then have it authencitated by the local China embassy or consulate as well.

Thnx, but where is the Foreign affair office, the clerk's office and the China embassy the consular?

You are resident there, you should know where the Foreign affair office and the Ciry clerk's office is located. As for the the China Emabssy or consulate, you can just choose the correct one according to the consular division on this page: https://www.travelchinaguide.com/embassy/canada.htm
