There were a few legacy media articles and twitter threads prior to this event complaining about it and claiming Canadian Tire didn't endorse it and implying that is might be canceled. See the following article and the twitter threads linked to it:

While some of the twitter threads linked to the above article seemed to have gotten a moderate amount of engagement, I suspect most of the accounts responding to the threads are bots or paid government intelligence operatives. They often use the same lines: "I shop at Canadian tire a lot and if they don't stop this event, I will not any longer." It's a common fill in the blanks type of line the left uses to pressure businesses they probably either never use or will never boycott if it's even a little inconvenient for them to do so.

Furthermore, what is interesting is that none of these keyboard warriors showed up in person to this event to counter-protest it. This is mainly what leads me to suspect that most of the twitter thread engagement is artificial. Those twitter threads are just trying to gaslighting the public into thinking that a lot of people like Trudeau and care enough to be vocal when he's being insulted. Except they don't care enough to get off their fat rear-ends and counter-protest something they claim they are so passionate about. The only reason I can think of for this is because they're either bots or paid shills and don't actually care. In fact, as far as I am aware, no one at all hassled anyone from the event, not any property owner nor anyone from Canadian tire. There were police there but they either kept their distance, sometimes patrolled the perimeter, and didn't engage anyone in any way.
