The economy of Canada was under great debt after the end of the world war 1.
In the world war 1, Canada was part of the British group. So when the British troop declared war on Germany, Canada automatically became a part of the war and the Canadian troops were sent for war.
This resulted in the huge rising of debts on the Canadian troops and the government.
With the help of the victory bonds, the government of the Canada had to borrow money from the people of Canada. This resulted in even more debt on the government.
