There are many sections missing and some of the microfilming quality is poor but some information is available. I believe that it is available through the LDS Family History Center. Further census' were taken in the "1" year (1861, 1871, etc.) There was a census done in 1842 but I don't think it was very complete. Look at http://www.archives.ca/02/02020205_e.html Good luck.
