February Report
Preliminary monitoring data from the last two weeks of February indicates that several lower-volume corridors produced the highest normalized accident risk when adjusted for traffic exposure. The Hwy 108 corridor between Blind River and Elliot Lake recorded the highest rate in the network, with two accidents on a route carrying relatively modest daily traffic. While the absolute number of incidents remains small, the normalized rate indicates a statistically higher crash likelihood per vehicle-kilometre travelled compared with busier urban corridors. Elevated normalized rates were also observed along Hwy 17 between Shabaqua and Ignace and between Marathon and Nipigon, both long-distance segments of the Trans-Canada Highway where traffic volumes are low but collisions can result in prolonged disruptions. In contrast, higher-traffic corridors such as the North Bay area experienced multiple incidents but did not rank among the highest-risk sections when exposure was considered.
The data also highlights several repeat incident environments where collisions or hazard events occur despite varying weather conditions. The Nipigon / Red Rock area recorded multiple weather-related advisories during the reporting period, identifying a persistent winter hazard zone along the Hwy 11 and Hwy 17 junction area. Additional recurring activity was noted along the Hwy 17 corridor east of Nipigon toward Thunder Bay, where weather advisories were issued repeatedly in the same localized stretch near Pass Lake Road. These recurring locations suggest infrastructure or terrain factors—such as elevation changes, lake-effect weather exposure, or alignment constraints—that may increase risk regardless of day-to-day weather variation.
Although the monitoring period remains limited, the early dataset shows that full closures and extended disruptions tend to occur on remote intercity segments, particularly along the Lake Superior North Shore where accident durations averaged longer than most inland corridors. One such example occurred on the White River to Marathon section of Hwy 17, where an accident produced a prolonged closure in an area that also contains a cellular coverage gap. While only a small proportion of total incidents occurred in LTE dead zones, these locations present heightened emergency response challenges due to limited communications and lower traffic volumes. As additional months of data are collected, Northern Road Watch will continue monitoring these corridors to determine whether the observed patterns represent persistent infrastructure risk or short-term seasonal variation.
Preliminary data from the first two weeks of monitoring indicates that several lower-volume corridors show elevated normalized accident risk when traffic exposure is considered. The Hwy 108 corridor between Blind River and Elliot Lake recorded the highest rate in the network, with two accidents on a route carrying relatively modest daily traffic. While the absolute number of incidents is small, the normalization process highlights that each vehicle-kilometre travelled in this section carries a higher statistical crash likelihood than on busier corridors. Elevated normalized rates were also observed along Hwy 17 between Shabaqua and Ignace and between Marathon and Nipigon, both remote segments of the Trans-Canada Highway where traffic volumes are lower and incident durations tend to be longer. By contrast, areas with higher traffic such as the North Bay corridor recorded multiple incidents but did not rank among the highest-risk sections once traffic exposure was accounted for.
The early dataset also points to several repeat incident environments where hazards appear consistently. The Nipigon / Red Rock area recorded multiple weather-related advisories during the reporting period, suggesting a persistent winter hazard zone near the Hwy 11 and Hwy 17 junction. Similar recurring weather advisories were observed along Hwy 17 between Nipigon and Thunder Bay, particularly near the Pass Lake Road area. Several of the month’s full highway closures occurred on remote north shore corridors where accident durations tend to be longer, including the White River to Marathon section of Hwy 17, which also contains a cellular coverage gap that can complicate emergency response. Although the dataset remains limited, the early results suggest that remote intercity corridors—particularly those exposed to Lake Superior weather systems—continue to produce the most disruptive incidents in the northern highway network.
LTE coverage analysis identified two incidents occurring in confirmed cellular dead zones during the reporting period, representing approximately 2 percent of all recorded incidents. While the share is small, the operational implications are significant. In these areas, drivers involved in a collision or witnessing a hazard may be unable to place a direct emergency call, and dispatch centers cannot receive immediate notification from the scene. This delay can increase response times, particularly on remote northern corridors where traffic volumes are low and the likelihood of another motorist reporting the incident may be limited. The Hwy 17 corridor between White River and Marathon remains the most notable location flagged for elevated emergency response risk due to the combination of documented LTE coverage gaps, relatively low average daily traffic volumes, and accident events that can produce extended closures. Although the current dataset covers only a preliminary monitoring period and does not yet establish a trend relative to previous months, the findings highlight a corridor where communications infrastructure gaps could directly affect incident detection, emergency dispatch coordination, and response timelines.
Wildlife corridor analysis for February identified one accident occurring directly within a designated wildlife corridor polygon, specifically within an overwintering habitat zone. This measurement reflects a deliberately conservative approach: only incidents that occur inside the mapped corridor boundaries are counted, rather than those occurring within a surrounding buffer area. While the number of confirmed in-corridor incidents during the reporting period was limited, 18 additional accidents occurred within two kilometres of mapped corridor areas, indicating that several highway segments pass through or adjacent to landscapes with significant wildlife movement potential. Corridors along the Lake Superior North Shore and the Algoma region, including sections of Hwy 17 between Blind River and Sault Ste. Marie and nearby secondary routes such as Hwy 108 between Blind River and Elliot Lake, represent areas where roadway alignment intersects forested overwintering and movement habitat. In late winter conditions typical of February, wildlife activity patterns often shift as animals move between feeding and sheltering areas, frequently during low-light periods at dawn and dusk, which increases collision risk where highways intersect these habitats.
Overall, the February reporting period shows a moderate level of highway safety activity across Northern Ontario, with a relatively small number of incidents producing disproportionately large disruptions due to the region’s long travel distances and limited alternative routes. While most incidents were resolved within a typical operational timeframe, several events resulted in extended closures that affected corridor reliability, particularly on remote segments of the Trans-Canada Highway and connecting regional routes. The data also suggests that a number of higher normalized accident rates occurred on lower-volume corridors, reinforcing the importance of evaluating risk relative to traffic exposure rather than raw incident counts alone. As winter conditions continue through the late season, persistent cold temperatures and intermittent snowfall—particularly along Lake Superior and northeastern corridors—are expected to remain key operational factors influencing highway safety.
Several data limitations should be considered when interpreting these findings. LTE coverage analysis reflects currently mapped cellular coverage and may not capture all localized gaps experienced by motorists. Wildlife corridor statistics count only accidents occurring inside designated corridor polygons and do not include incidents occurring in adjacent buffer areas where wildlife movement may still influence risk. Pre-incident precipitation analysis excludes cases where reliable weather history data was unavailable, and normalized accident rates are calculated using 2021 MTO AADT traffic volume estimates, which may not fully represent current traffic levels on some corridors. Northern Road Watch will continue expanding its monitoring dataset as additional months of observations become available. The project’s long-term mission is to provide transparent, data-driven monitoring of Northern Ontario’s highway network in order to support safer travel and more informed infrastructure planning across the region.
