I first heard about this last year when I attended a conference at the Library and Archives Canada, and subsequently wrote an article about Chinese-Canadian immigration for Internet Genealogy Magazine last fall.
At that time, Janet Tomkins, Genealogy Librarian of the Vancouver Public Library, said that the wiki which was under development at that time — ccgwiki.vpl.ca — would soon be added to the page on which had been set-up by the library she works for, with the Library and Archives Canada
According to a press release, "The goal of the wiki is to create a portrait of the early Chinese-Canadian community by collecting and sharing the stories of individuals of Chinese origin who were born in Canada in the 19th century."
If you go to the wiki, you will see that already there are 461 indiduals in the database, with a separate profile on each one.
It is hoped that people whose ancestor inmmigrated to Canada can now go to the wiki where they can register for free and contribute to the profiles by adding biographical details, photographs, and document images.
