She was an ardent supporter of conscription, and campaigned in favor of
the Union Government, despite her own and the Macneill family history of
support for Laurier and the Liberals. When women were temporarily allowed
the vote (if they had a male relative serving overseas), in the government's
hope to support conscription, Montgomery--who had never hankered for suffrage--eagerly
cast her first ballot in December 1917 for a man from Uxbridge who supported
Borden's Union Government and conscription, Lt.-Col. Samuel Sharpe, commander
of the 116th Battalion overseas.
