Why did many Spaniards and Canadians support the colonists?

Many Spaniards and Canadians supported the American colonists during their struggle for independence due to shared values of liberty and resistance against British colonial rule. Additionally, Spain saw an opportunity to weaken British power in North America, aligning their interests with those of the colonists. In Canada, some groups sympathized with the revolutionary cause, driven by a desire for autonomy and a shared experience of colonial governance. This support was also motivated by the hope that a successful revolution could inspire similar movements against British authority elsewhere.
