On the personal history you should mention your main activity such as work/unemployed. If you became unemployed and came over to the province where your sister lives and then after you moved to another province you got employment then yes it all should be mentioned in your personal history (as that would mean that your main activity changed). Then you would have to put your sisters address in the address history as well as there shouldn’t be no descrepancies between your personal and address history. But if you continued being unemployed even after you moved to another province and your main activity didn’t change then I don’t think your stay at your sisters needs to be mentioned. But it’s my opinion.
