Police were called to the Wilmington Avenue and Combe Avenue where a car and truck collided just after 1:00 p.m. 

The area is near the intersection of Allen Road and Sheppard Avenue West.

Officers confirm one of the injured men is in his 30s and the other in his 40s. 

Mahendra Brahmbhatt lives in the neighbourhood and told CBC News that there was one person in each vehicle.  

"Severely injured person was the person sitting in the truck, he was bleeding," he said. "And in the car, that person, he was conscious. He was just shouting."  

The impact caused the vehicles to land on a home's front lawn, according to police. 

Wilmington Avenue was been shut down between Acton Avenue and Clifton Avenue for the investigation.
