[3] However, another colony, the Province of Canada, comprising present-day Ontario and Quebec, heard news of the planned conference and asked that the agenda be expanded to discuss a union that would also include them.
Owing to the unexpectedly large number of visitors in the city, a sizeable proportion of the Canadian delegates remained aboard the Queen Victoria while others found accommodations at the Franklin.
The representatives from the Province of Canada dominated the conference, overshadowing the concerns of the Maritimes, and laying out foundations for the union that benefited them the most.
One Canadian delegate, George Brown, spent two days discussing the details of the proposed constitution, which would keep Canada within the British Empire.
Most of the Maritimes were convinced that a wider union including the Province of Canada would also be beneficial to them; Prince Edward Island was unsure, however, and very much against confederation.
[10] The delegates from the respective provinces met again on September 10 and 12, 1864 in Halifax, Nova Scotia, where further discussions arose regarding the union and idea of the constitution.
Some historians believe that Confederation was a pre-emptive action to reduce the chances that territories to the north and west of Canada would be annexed by the United States.
