Independent highway incident tracking for Northern Ontario
Places where collisions keep happening: accidents within 500 m of an earlier recorded incident. Tap a location to see its history.
Collisions that stayed listed on Ontario 511 for 4 hours or more. The 511 listing can stay up after the road has partly reopened, so this is how long 511 reported the collision, not always how long the road was blocked.
Local news coverage of crashes, closures and enforcement on northern highways. When a crash story matches an incident Ontario 511 listed, we link the two.
Headlines link to each outlet's own story. We list headlines and link to them; we don't copy articles.
Our monthly, seasonal and annual reports on highway incidents in Northern Ontario. Each one has a short summary and the full report as a PDF.
Northern Road Watch monitors highway incidents across Northern Ontario in near real-time, sourced directly from Ontario 511 and updated every few minutes. Each accident is automatically tagged with weather conditions, road state, camera snapshots, wildlife habitat proximity, LTE coverage, and lighting conditions at the time of detection. Construction and routine maintenance are excluded from statistics.
⚠️ Limitations: Incident durations reflect how long an event appears in the 511 feed, which may not match actual road closure times. Camera snapshots show the nearest available camera — it may be several kilometres away. LTE data reflects mapped coverage and varies by carrier, terrain, and conditions.
