There seems to be a misconception in certain groups and media sources that this protest is "huge". I suspect pro-convoy news sources are trying to hype this thing up like it's some massive event with more support than it actually has. It's definitely intimidating local residents but it's not solely because of the numbers of people attending but just because of all the big trucks, honking, harassment, and other vehicles. But if there were no trucks and these protestors were on foot, this really wouldn't be all that big of a protest.
I've witnessed a lot of protests in this city, this protest is definitely the longest, loudest, and the most dynamic, HOWEVER, it is a not the largest in terms of numbers and it's not even close. The city thinks we had about 10,000 people at the peak of it last weekend. It's possible it was a bit more than that, but if so not by much. This estimate is consistent with photos of the event from the air and in comparison to other events I've seen and the numbers reported from them (That I believe are fairly accurate).
A few examples of substantially larger protests and events;
The 2005 anti-Bush protest was MANY times larger than this one. It's really not even remotely comparable and it would dwarf this protest by many times over. To think this protest is comparable to a really big protest like that is honestly laughable.
The 2021 George Floyd protest in Ottawa brought about 20,000 people, so that was about double the size of this one in terms of people who made an effort to actually physically attend.
A typical Ottawa "Capital Pride" event also a little bigger in numbers. It should go without saying that a typical Canada Day event is also many times larger in terms of attendance.
A Sens game (Stadium capacity is around 19,000) or literally any large sports event or music festival. Justin Bieber has single handedly brought more people to Ottawa than the entire "Freedom Convoy".
Hope that puts things a bit more into perspective for anyone who may be wondering how this stacks up.
