Why Canada has a terrible "U.S. Problem"

When the American colonies broke away from Britain, the northern territories chose a different path—staying under British rule and defining themselves in contrast to the United States. Over the next two centuries, the U.S. repeatedly shaped Canada’s economy through trade policy, tariffs, and control of market access, steadily tying Canada’s prosperity to American demand. Today, Canada is one of the most closely integrated economies with the United States: wealthy, but heavily dependent on a single partner. In recent years, protectionist policies, new tariffs, and “America First” politics have shown how quickly that dependence can turn from advantage into risk. Canada was built to remain separate from the United States—but its future may depend on how long it can keep that independence in practice
