List of Canadian Politicians Who Have Crossed The Floor - 1910s

1910s

• 1911: Louis-Joseph Papineau, Liberal MP since 1908, re-elected as a Conservative in 1911.

As a result of the Conscription Crisis of 1917, Conservative Prime Minister Sir Robert Borden forms a Union Government in an attempt to win support across party lines. Opposition leader Sir Wilfrid Laurier refuses to support the new government but many of his MPs cross the floor to support the new government either as Unionist or Liberal-Unionist candidates in the Canadian federal election of 1917. Those loyal to Laurier run as Laurier-Liberals. Conversely, a number of Quebec Conservative MPs abandon Borden over the conscription issue and join the Liberals.
