Contacting my account manager is about as usefull as your reply. I was just asking for usefull information from non-sales ESRI and I get a d-bag response.
Business Analyst Canada on ArcGIS 10 is now being developed by ESRI Canada so I you could contact them to see what the current time frame is.
Of note the Canadian demographic data is quite different than ESRI's United States demographic data as the current release (Business Analyst Canada 9.3.1) is 2008 so I can not definitively say what vintage for version 10 would be.
