A helping hand from north of the border

Anyone who's working in Wisconsin and Michigan knows how often Canadians pop up and need to be traced back across the border. I'm not going to pretend to any expertise whatever, just thank the Resource Shelf for including a pointer to Library and Archives Canada and its selection of online genealogical databases, some of them including original images. Resources include censuses, marriage and divorce records, as well as immigration and naturalization, land, military, and directory records.
