I work for a company that is looking to buy all the civic address data for Canada. I've been Googling around and I have yet to find a solution that is not pay per request.
We need it so that it can be integrated in to an ArcGIS server.
What we want to do with the data is tie to in to a Geodatabase where people will be able to search their address and have information pop up about their house. We have the metadata for each location but our current addressing system is partially interpolated/inaccurate (not accurate to the level that we'd like).
We're looking for source data.
