In the U.S., real estate search sites like Zillow have attracted huge enormous user bases and record venture capital funding rounds. This was an idea whose time had come, given the widespread consumer distaste with having real estate sales information controlled by the Multiple Listings Service. A far cry from the Internet's open ethos. Not quite so in Canada. Canadians have tended to be stuck with the Realtor.ca (also accessible at MLS.ca) site.
