Answer: • As the colonies grew, they were building railroads and roads, which cost a
great deal of money. If several smaller colonies combined, they would
have more taxes and more money to pay their debts as they grew.
• The “Great Coalition”, which involved leaders such as John A. Macdonald,
George Brown, and George-Étienne Cartier, had proven by their influence
that it was possible for English and French-speaking Canadians to agree
on big questions such as government reform.
• In some of the colonies, especially Canada East and Canada West, there
was one government problem or crisis after another. A new system of
decision making, with one central government and provincial governments
to deal with local issues, might help make government more stable in the
colonies.
• The United States had gained their independence from Britain in 1783
after a long war. Not long after this, the states became involved in a war
amongst themselves, (the Civil War). The British colonies did not want
any more wars, and by combining under one strong central government,
they might avoid further wars. They would also have a stronger military
defence
Explanation: Main Reasons for Confederation
• Britain wanted to become less involved in the government of their
colonies, because it was very time-consuming and expensive. It was time
for the colonies to become more independent.
• It was necessary to work out a new system of government to help solve
the continuing problems between the English- and French-speaking
representatives of the united province of Canada, who had different
priorities.
• The United States was very rich and powerful, and it was always looking
for new lands. The U.S. wanted to take over the lands of Canada, and
they were trying to convince the people of Canada, many of whom were
American immigrants, that this would be a good idea.
