The Constitution Act of 1915 added two more senate seats for Manitoba, bringing the total to six.
The Constitution Act of 1915 also amended Section 26 of the Constitution Act of 1867 to add a fourth regional division, called the Western provinces, made up of British Columbia, Alberta, Saskatchewan and Manitoba, to allow two senators to be appointed on a regional basis.
Each senator may choose to designate a geographic area within Manitoba as his or her division.
