Is there anything I can do about being lied to about the km on a vehicle ?

I bought a truck off kijij And the seller lied about the actual Kms, I just recently pulled a carfax after 2 years of owning it and the Kms are really high . I m wondering if there s anything I can do? I have a bill of sale with his signature / license number and name stating that the car actually had way lower km
