A cyclist is dead after a collision with a truck in Leslieville on Wednesday morning.

Toronto police were called around 8 a.m. to the area of Jones Ave. and Dundas St. E., where a truck hit a cyclist. Sgt. Thomas Reimer told reporters on the scene that both vehicles were travelling west on Dundas.

He said the truck attempted to make a right turn to Jones when the collision happened. Paramedics said the man, believed to be in his 50s, suffered life-threatening injuries and was taken to hospital, where he was pronounced dead.

The truck driver remained at the scene, police said.

The incident comes one day after the city launched the Vision Zero challenge, where the public is asked to determine what safety improvements policy-makers should prioritize.

It also comes as police services across the country are participating in Canada Road Safety Week, which targets “high-risk driving behaviour that puts pedestrians, cyclists, drivers, passengers and other vulnerable road-users at risk.”

In the press release, Toronto police said they are focusing their efforts on the “Big 4” contributors: speeding, distracted driving, impaired driving, and aggressive driving behaviour.

This is the third collision involving a cyclist in the last 24 hours.

Another cyclist was seriously injured following a collision with a vehicle near Lake Shore Blvd. and Colborne Lodge Dr. just before 4 p.m. Tuesday.

Police said the driver was travelling east on Lake Shore while the cyclist was going south on Colborne when the crash happened.

The cyclist, a man in his 30s, was taken to hospital with life-threatening injuries. The driver remained on scene, police said.

A male cyclist was also injured after a collision with a coach bus in the area of Queen and Jarvis just before 1 a.m. Wednesday. Police said the man was taken to hospital with minor injuries.
