Ah, I had forgotten about these little tidbits.
familysearch.org has Canada, Lower Canada Census, 1842 and Canada, Lower Canada Census, 1831. RootsChat won't allow me to make a direct link to the website but if you go to it and then click on Canada then scroll down you will find them.
You can also access them through the Canada National Archives website, under census ... RC won't let me make a direct link to that either. It puts you directly through to the familysearch records in question. These will be free to use.
