Dangerous highways
Travel conditions will deteriorate throughout Boxing Day along Highways 17 and 11, where a persistent wintry mix will linger and create dangerous driving conditions.
While the system will primarily affect roadways across northwestern Ontario, its impacts will extend east along the highways towards Kapuskasing, Wawa, and Timmins.
Consider avoiding or postponing any travel on these highways if at all possible during this time. If you must travel, make sure to have a safety kit in your vehicle with you, drive according to conditions, and let a friend or loved one know where you are heading. It may also be a good idea to utilize four-wheel drive if your vehicle is capable.
In addition to roadway impacts, gusty winds in combination with the icy conditions could result in localized power outages.
