Travel will be delayed by messy, wintry system in eastern Ontario, Quebec

A wintry system will move into eastern Ontario and southern Quebec on Tuesday, challenging drivers and a couple of commute times

Even though we are inching closer to the official start to winter, many drivers have yet to put their snow tires on, so it's a reminder to adjust to the changing road conditions as things begin to deteriorate. See the timing details, below.

Through the overnight hours, persistent snow continues for Ottawa and Gatineau, with this time period being the heaviest for Montreal, as well. That means the Wednesday morning commute will likely be a slick and slow one for many. Be sure to plan ahead.
