This organization, United North America, is 9 years old and surprisingly (considering the imperialist tendencies of the USA and the goal of this organization) is Canadian.
They raise some good points on how Canada would in fact become stronger if this happened.
A few such points:
Quote
Just as decreased taxation can actually result in increased tax revenues for governments, elimination of trade restrictions would actually result in increased trade, economic stimulus, further increased government revenues and most importantly, increased prosperity for the average North American. Overall, the removing of myriads of redundant agencies and consolidating everything from budgets to currencies would eliminate waste and streamline the North American economic engine.

North American air, space and sea are already under the aegis of NORAD, a permanent agreement binding the security of Canada and the United States together domestically. Abroad, the two countries work together militarily through organizations such as NATO. Such arrangements have helped create an integrated, interoperable and cooperative North American security force within our continent and throughout the world. However, the overall defensive capability of North America is not enhanced, but rather diminished, by the fact that we continue to have two sets of military and government departments dedicated to our joint internal security. The burden of nearly doubling the administrative costs may have a debatable effect on the security of the continent.

From a canadian perspective, Canadians would gain a seat in the most powerful halls of government and finally have a voice in setting the course for the continent and the world. Economics and security are often discussed in relation to continental integration, and treaties turn these discussions into realities. Yet, too often the political influence of the US over Canada increases as a result of these agreements while Canadians remain helpless to similarly influence the US. The softwood lumber dispute and the mad cow crisis are perfect case examples of such a relationship.

The border that divides us today was not created out of any interminable or irresolvable issues. It was instead simply a line drawn by an imperial power that has long since left the shores of North America. While the political disputes of the 18th Century have long since disappeared, their legacy continues to live on in the form of the border. A United North America would finally heal the wound of the first civil war that divided the people of North America, and bring about a reunion of historical proportions.

Combined, Canada and the US would make the largest nation on Earth with the largest amount of freshwater supply.
