Most Dangerous Intersections in Markham

Some intersections in Markham see more collisions than others due to traffic volume, turning patterns, and visibility issues. Knowing where and why accidents happen can help drivers stay alert — and can also become important when determining how a crash occurred and who was at fault.

While any intersection can be the site of a serious collision, certain areas consistently present higher risks.

High-Risk Intersections in Markham

Below are several intersections in Markham that are commonly associated with heavier traffic and a higher likelihood of collisions.

Highway 7 & McCowan Road

This is one of the busiest intersections in Markham, with a mix of commercial traffic, turning vehicles, and frequent congestion. Left-turn conflicts and sudden stopping often lead to rear-end and side-impact collisions.

Highway 7 & Kennedy Road

Heavy east-west traffic along Highway 7 combined with turning vehicles onto Kennedy Road creates a high-risk environment. Drivers attempting to beat lights or navigate tight gaps can increase the likelihood of serious crashes.

Steeles Avenue East & Markham Road

As a major boundary road with constant traffic flow, this intersection sees frequent congestion and lane changes. Rear-end collisions and turning-related accidents are common, particularly during peak hours.

Warden Avenue & Highway 7

This intersection combines high-speed traffic with complex turning patterns. Visibility and timing can be issues, especially for drivers making left turns across traffic. These can often result in catastrophic accidents.

Major Mackenzie Drive & Woodbine Avenue

This area experiences steady traffic from both commuter and local drivers. Speed variation and turning movements often contribute to collisions, particularly during

busier times of day.

Why These Intersections Matter in Injury Claims

Where an accident happens can sometimes help explain how it happened. Busy intersections often involve:

• multiple witnesses

• traffic signals and turning restrictions

• potential access to nearby camera footage

• complex fault scenarios involving more than one driver

In many cases, proving what actually occurred requires more than just the drivers’ accounts.

We often see situations where key evidence includes:

• police notes and collision reports

• witness statements

• 911 call recordings made immediately after the crash

• intersection or nearby camera footage, which may only be available for a limited time

In more serious cases, collisions at busy intersections can also result in injuries that are not immediately obvious, including concussions or other head injuries.

Understanding how those injuries are assessed and documented can become an important part of a claim.

Can You Request Traffic Camera Footage After an Accident in Markham?

In some situations, yes — but timing is critical. Depending on the location, there may be:

• municipal traffic cameras

• nearby business surveillance systems

• transit or dashcam footage

However, many of these systems only retain footage for a short period of time. If no request is made early, that evidence can be lost.

This is one of the reasons why early investigation can matter in more serious injury claims.

What To Do After an Intersection Accident

If you are involved in a collision at an intersection in Markham, a few steps can make a difference:

• Seek medical attention, even if injuries seem minor at first

• Report the accident where required

• Take photos of the scene, vehicles, and surrounding area

• Obtain contact information from any witnesses

• Be cautious when speaking with insurance companies before fully understanding your situation

Even relatively straightforward collisions can become more complex when injuries develop or fault is disputed.

Final Thoughts

Intersections are one of the most common places for serious collisions to occur. Understanding where risks tend to be higher — and how accidents are investigated — can help you better protect yourself both on the road and afterward.
