The motion was introduced to celebrate the 80th anniversary of the landmark court challenge that allowed women to hold seats in the Senate of Canada.

The Motion to recognize the women was introduced by Conservative senator Ethel Cochrane and seconded by Consiglio Di Nino. After debate, the motion passed without opposition. This was the first time in the history of the Senate of Canada that the title of honorary Senator was awarded to anyone.
