No Accident. False Police Report Filed. Need Advice!

My dad recently received a letter stating that he is being sued for a car accident he was involved in for bodily injury that occurred in mississauga. Here's the thing, he was on vacation that same time and drove his car to new burnswick. He received a statement of claim stating that his car was unsafe, and driving was unsafe causing severe bodily injury. The car is a 2015 civic, and I remember he had bought it from a dealership used with safety like 2 months before that.

So no accident happened, car was in another province, a false police report was filed by the other party, and no correspondence was made with my dad or his insurance company at all. He is the only person that uses his car, and it was stated it in statement of claim that it was driven by a lady we have never heard of. When he went to the local police station, the officer stated there was indeed a report filed with that license plate and it was a white 2015 civic... I am baffled.

What can one do in this situation?

Have you contacted your insurance company?

Apparently what happened was it was reviewed again. The cop that made the police report wrote the last digit of the license plate wrong. It was a completely different car, and on the citation issued to the at fault driver, it was obvious.
