Is there a way to convert an entry from the 1881 Census of Canada to a street address. I have found members of my family in the 1881 Census in District 105, Sub-Dist A, Div 2, Page 26, Household #125. I cannot find anything more and would like to find a street address in Ottawa for the entries.

Have you consulted an Ottawa city directory? This would give an address and allow you to track the family between each census.

My great-great grandfather is known to have worked in the lumber camps in the Upper Ottawa River Valley roughly in the 1860's. Were there log books kept at the lumber camps? What other resources are available to trace his time spent in the Valley?

These are well written up ( the camps, I mean) in books in the stacks at Weldon Library (University of Western Ontario). The Wright Bros. had many camps; their records could very well be in the National Archives in Ottawa or with the Historical Society in that area. Perhaps also in the Toronto Reference Library. As for other resources, visit the Carleton CountyGenWeb

Where is the "Victoria Ward", Ottawa, Ontario, Canada?

The Archives of Canada offers maps of census districts here: http://www.archives.ca/02/020122/0201220405_e.html. You can see where Victoria Ward, and other census wards are located by viewing the maps.

My Great Grandfather attended a university in Canada about 1850. Where could I find a list of universities operating during that time?

The Universities operating in Ontario in the 1850's were the University of Toronto (est 1827), Queen's University (est 1841), and College of Bytown (now known as University of Ottawa, est 1848). Universities elsewhere in Canada included Quebec's McGill University and Bishop's University (est 1843), New Brunswick's University of New Brunwick (est 1785) and Mount Allison (est 1839), and Nova Scotia's University of King's College (est 1789) and Dalhousie University (est 1818).
