The 7th Canadian Infantry Division was an infantry division of the Canadian Army, mobilized in the spring of 1942 and assigned for home defence within Atlantic Command, during World War II.

At the time it was assumed it would consist of volunteers and proceed overseas.

By the summer of 1942 it became obvious that there would not be enough volunteers, so National Resources Mobilization Act (NRMA) conscripts were assigned to the regiments of the Division to bring their numbers up to war establishment strength.

This meant that the Division could only be used for home defence, unless the Parliament of Canada ruled that conscripted men could be sent overseas.
