Can an American citizen not residing in Canada get tourist visa or a z visa in Montreal.

I am American and have resided and worked in China for years. My work permit is until 5.30.20. I could not return to China to get my work my visa so it expired 3.8 and I need to renew it. The NY Chinese Consulate closed and returned my application. Can I renew my work permit or get a tourist visa in Montreal?
