Why haven't Canada and America merged?
What are some political and economic differences between the two countries?
One significant political difference is that Canada has a parliamentary government, while the United States has a presidential system. Also, the two countries have different legal systems, with Canada's being based on British common law and the United States being based on the Constitution. In terms of the economy, Canada and America have different industries and trade relationships with other countries. For example, Canada has a strong natural resource-based economy, while the United States is more focused on manufacturing and services.
