<human>: Summarize the given text in a few sentences.

Ok, so here is the story. When I was driving home from the gym today I admittedly cut off another driver at a 4 way stop. By this I mean he had the right of way at the intersection and yet I went first. He honked, I acknowledged my mistake that I should have waited (I am a rather new driver being only 18 years old) and then he followed me through the neighbourhood to my house in his blue pickup truck. I pulled up to the top of my driveway, got out and went inside, he parked at the end of my driveway and walked to door. He yelled at me "COME TO THE DOOR". Now me not being an idiot and seeing that this guy was twice my size (I am only 165lbs 6ft 1inch) I told him "No" through the door. My door has a small window near the top so I was able to see him and he was able to see me. He then says "I just called the cops, I have your license plate! etc..." and proceeds to ring my doorbell and bang on my door for a LONG time, maybe 30mins roughly. He eventually walks back to his car, finally given up realizing that there is nobody else home and that I will not be coming to the door to get my ass kicked. A few minutes later he comes back to the door and sticks this note through the door. 

The note says the following: "Your plate number has been reported to Toronto Police. You flew through two stop signs. My brother in law is a cop and will name sure your parents are informed. Be very careful who you act like a smartass towards"

Now the above note is clearly bullshit, I did not "fly" through any stop signs. I cut him off at a single stop sign.

Now my question is: Reddit, should I be worried? Anything I should do? (I am in canada btw)
<bot>: I cut a guy off, he follows me home and proceeds to threaten me both physically and with potential implications of the law.
