There have been various movements within Canada for secession.
There is a secessionist movement in Newfoundland based on its unique history, and as a result of its grievances and broken promises with both the federal government and the government of Quebec. Prior to 1949 the area was a self-governing Dominion (Dominion of Newfoundland). "The root of our trouble is centred in the relationship between the two countries, between Newfoundland as a country and Canada" according to James Halley, a former lawyer involved in negotiating a deal to get Newfoundland into Canada in 1949. According to a July 2003 report, secessionism was on the rise In 2004, a "flag flap" occurred when the premier of Newfoundland and Labrador removed all Canadian flags from government buildings and raised provincial flags instead. Tensions have since eased; however, a non-organized movement has emerged amongst citizens and the ability of potential premiers to appeal to a strong sense of Newfoundland nationalism is imperative to forming a government.
The secessionist movement in Newfoundland and Labrador is most commonly associated with a flag under several names, including the "Pink, White and Green", "Flag of the Republic of Newfoundland & Labrador", or officially as the Newfoundland Tricolour.
Shortly after the Confederation of three British colonies (Nova Scotia, New Brunswick and the Province of Canada) to form the Dominion of Canada in 1867, opponents of Confederation in Nova Scotia began promoting the withdrawal of that province from the new confederation. The Anti-Confederation Party won 18 of the 19 Nova Scotia seats in the new Canadian House of Commons in the 1867 general election, and 36 of the 38 seats in the Nova Scotia legislature, but did not succeed in achieving independence for Nova Scotia.
In 1990, just before the failure of the Meech Lake Accord, then-premier John Buchanan predicted Nova Scotia and the rest of Atlantic Canada would have to join the United States if the accord failed.
