Protesting and Mischief Thuggery in Canada: Who Are the Protesters - Does Any Media Source Look To Discover This?

An honest and genuine question - How many protesting are actual Canadian citizens versus say, environmentalists coming across from USA, or arriving internationally, international students jumping on the bandwagon, visa holders with no ties to Canada other than simply working here for a couple of years, vacationers/temporary entrants, etc?  Yes, lots of people siding with the First Nations and the Hereditary Chiefs.  From what I've seen from the interviews on the news, usually post-secondary age protesters (which may be reflective of the blind faith Liberal, cancel culture at universities today).  I ask because does it fully reflect "Canadian opposition"? Maybe it does, but the media does not fully investigate these parts of these types of situations to report the full story.  I would raise this question not just for the current protesting thuggery and mischief that is happening, but also to such past events as the red patch student protests in Montreal, G-20/G-7 summits, etc.
