In the 1867 Canadian Confederation, three provinces of British North America--New Brunswick, Nova Scotia, and the Province of Canada (which upon Confederation was divided into Ontario and Quebec)--were united to form a federated colony, becoming a sovereign nation in the next century . Over its history, Canada's international borders have changed several times, and the country has grown from the original four provinces to the current ten provinces and three territories . The ten provinces are Alberta, British Columbia, Manitoba, New Brunswick, Newfoundland and Labrador, Nova Scotia, Ontario, Prince Edward Island, Quebec, and Saskatchewan .
