When the American Revolution happened, 13 British colonies declared independence. There were other British colonies in North America — namely in Canada — that did not join them. Were these other colonies politically distinct from the thirteen American colonies in any way? Did they have some other administrative status that made them less antagonized by the Stamp and Tea Acts? Did the UK administer them more directly? Was there any kind of border that distinguished them?
There were indeed substantive differences between the Thirteen Colonies and Canada. Canada had been acquired by England after it won the Seven Years War against France, in 1763. After that, there was a royal governor ( James Carleton at this time), like in the lower colonies, but there was no legislature. There was also a loyalty oath to the king, for all public officials, that contained anti-Catholic language. As most of the French were Catholic, that effectively shut out the majority of the population from any local government. A local militia was started- and apparently gained recruits and French officers. But it then was dismissed- and the officers not even put on half-pay, which was considered a pretty shabby thing to do.
When the lower colonies began to make trouble, the British government realized that the meager forces, poorly-maintained forts and weak government in Quebec was quite vulnerable. Some of the English residents ( though not at all a big population) were also receptive to the idea of independence. In response, Parliament passed the 1774 Quebec Act, which finally removed barriers against Catholics. It also extended the boundaries of Canada west to Minnesota, down to the south as far as Ohio. It did not create a legislature; just a governors council.
The Quebec Act didn't make the Quebecois very happy- they still didn't have a legislature, and Carleton selected mostly the seigneurs, the largest landholders, for his council, leaving out the merchants and clergy, who were often better-educated and more capable. And the Act did greatly enrage the Thirteen Colonies. Some of them ( notably the Boston radicals) were biased against Catholics, and many had real aspirations of the western territory for themselves. They lumped the Quebec Act into what they called the Intolerable Acts, one of their greater grievances.
There was a mission sent in early 1775 to Montreal by the Massachusetts Committee of Correspondence , to see if any of the British there would support joining the Thirteen Colonies, sending delegates to a Congress, but found no interest. During the War for Independence there were some Canadians who lent a little assistance. There was a Canadian Regiment in the Continental Army helping Benedict Arnold in his expedition against Quebec. And there was markedly little resistance when a pretty small Continental force under Richard Montgomery appeared at Montreal, forcing governor Carleton to flee. But there was never a possible organized revolt by the Canadians. There was strong Native support for the British, also. The American invasion turned into a disaster: a smallpox epidemic ripped through the Continental army and greatly thinned the ranks, and when Burgoyne arrived in 1776 with a good sized army, they had little trouble pushing the Continental army back into New York. It would be after the War, after the US ratified its Constitution, that Canada would begin to get real local government, was divided into provinces, given legislatures, had elections, etc.
There's always more to be said, but in the meantime you can find some answers about Canada (or "the Canadas", as it was known then) and the dilemma it faced during the American Revolution in this post from u/enygma9753 (see link below):
Quebec did not have its own assembly in the years leading up to the Revolution. The colony was predominantly French and Catholic, ruled by a governor and executive council. The French had outnumbered the British in Quebec by 25 to 1. Existing anti-Catholic laws meant that the highest political and military offices remained the domain of English Protestants, although the British retained much of the colony's administrative and religious hierarchy: the seigneurs and clergy.
The generous accommodation of language, property and religious rights offered to Quebec in the 1774 Quebec Act helped to secure its loyalty in the brewing conflict. More accurately, they promised to uphold their oaths to keep the king's peace. This did not mean, however, that they would take up arms for the Crown -- most would remain neutral. The rebellion in their eyes was a fight between two groups of English Protestants, neither of whom had earned their trust.
There was a palpable fear in Quebec that they may lose their civil liberties by joining the revolt.
