I don't think I ever saw three separate rear-ends in a single drive. I can't say for certain that I ever saw two. I didn't drive it every day, but I probably did 100 such commutes.
You sound either like you're massively exaggerating or live someplace with apocalyptic traffic.
I drive 30 miles through Chicago traffic on the Interstate everyday. I see at least 3-4 accidents per week (people pulled over to the side of the road, out of the way, or at the accident investigation sites.) Most of these are minor fender benders. I'm sure if I was in rush hour traffic for the full 4-6 hours (not just my 90 minutes of commute) I would see way more. They mostly happen in near bumper-to-bumper stop and go traffic (someone misses the guy in front of them stopping) or when traffic unexpectedly comes to a standstill from going 10-20 MPH.
Every morning and at least two of the evenings. And the weather has been reasonable. I typically see 4 to 5 Teslas a day during my commute... driving sedately, and they aren't they ones involved in the accident.
Maybe we'll break the streak tomorrow and have no accidents.
Yeah, if you spend 4-6 hours a day in traffic, you'd see a lot of accidents. That... seems uncontroversial.
The Greater Toronto Area has approx. 20% of Canada's population (~35M). If we assume that 300 injuries are evenly distributed across Canada, which seems unlikely due to how bad the driving conditions are on the 401 and DVP, there are ~60 injuries per day in the GTA of various severities.
I don't think someone encountering ~3 per commute during rush hour is unreasonable.

A few months ago I saw a guy, face-down in his phone, smash into an existing accident that was already surrounded by fire trucks. That was amazing.
The guy I was replying to said that he saw at least 2 every commute, often more. (Edit: Actually, sorry, 2 every day, not every commute).
People rear-end each other in my city every day. On my commute, I'll come across two a day. Wet days, a few more. The other five directions headed into the city I would expect to see similar statistics to my experience. Just listening to traffic radio, there's going to be at least five crashes around the city; almost always more. They don't report on fender benders.
