This was the first election in which Alberta and Saskatchewan voted as provinces. Following their creation in 1905, the two new provinces continued to be represented by MP's initially elected under the old Northwest Territories riding boundaries, some of which straddled the new provincial border. The remainder of the Northwest Territories that previously had Parliamentary representation lost it, although parts of the NWT would gain or re-gain representation after being added to Manitoba, Ontario and Quebec in 1912. A seat would not be created for the NWT itself again (which then contained the modern NWT and Nunavut) until 1949.
This is the most recent election in which a prime minister was able to lead their party to a fourth consecutive mandate.
