In 1841, by the Act of Union Upper Canada(now Ontario) and Lower Canada (now Quebec) were combined into the Province of Canada. Along with this came a name change - Upper Canada became Canada West and Lower Canada becamse Canada East. A legislative body was created consisting of a Legislative Assembly and a Legislative Council. This parliament governed the Province until Confederation in 1867. At this time Canada West became Ontario and Canada East became Quebec.

For political reasons the post office for the two houses rotated among a number of cities. With the Act of Confederation and the creation of the Dominion of Canada the legislative post office was permanently established in the new capital - Ottawa.

The chart below shows cities in which the legislative bodies met.

In April 1849 arson by a mob in Montreal destroyed the building in which the Legislature met. Meetings continued in Montreal until the Legislature moved to Toronto.
