The recent controversy over residency in their “home” province by Canadian Senators is a puzzle. Apparently there is no definition of residency. Senators must be in Ottawa to attend Senate sessions. I dont know how many days that is per year There are Senate committee hearings. Their attendance is judged basically by attending sessions and hearings. Somehow they have to “live” in Ottawa. They must also be permanent residents of the province for which they were appointed. In Saskatchewan one must live 182 days of the year to qualify for a provincial health card. Senator Wallin seems to have run afoul of that one. She is in Saskatechewan only some 160 days. Perhaps the members of the Senate should be selected for their ability to be in two places at the same time.
