Where can I obtain proper a certificate of single status and a Birth certificate in Victoria, BC?

I was married and divorced in the United States of America. However, both my ex-wife and I both have US and Canadian citizenship. Presently, I am living in Canada and I wish to remain living in Canada. However, my birth, marriage and divorce all occurred in the USA. How and where can I obtain the necessary documentation of my birth, marriage and divorce in Victoria, British Columbia, Canada so that I can marry a Chinese lady in the People's Republic of China and come back with her to live in Victoria, British Columbia, Canada?
