Study identifies Canada’s worst traffic bottlenecks

Canada’s top 20 most congested traffic bottlenecks may cover just 65 kilometres, but they collectively cost drivers over 11.5 million hours and an extra 22 million litres of fuel per year. These are two findings of Grinding to a Halt, Evaluating Canada’s Worst Bottlenecks, released by the Canadian Automobile Association (CAA). Studies show that bottlenecks are the single biggest contributor to road delay, far outpacing traffic accidents, inclement weather and construction. The report provides data-based

Canada’s top 20 most congested traffic bottlenecks may cover just 65 kilometres, but they collectively cost drivers over 11.5 million hours and an extra 22 million litres of fuel per year. These are two findings of Grinding to a Halt, Evaluating Canada’s Worst Bottlenecks, released by the Canadian Automobile Association (CAA).


Studies show that bottlenecks are the single biggest contributor to road delay, far outpacing traffic accidents, inclement weather and construction. The report provides data-based evidence for decision-makers to use when making decisions on infrastructure investment and environment policy.  It includes the cost to Canadians of these bottlenecks in terms of lost time, productivity and added greenhouse gas emissions.

“Traffic congestion is a major source of stress for Canadians. Our study concludes that traffic bottlenecks affect Canadians in every major urban market, increasing commute times by as much as 50 per cent,” said Jeff Walker, vice-president of Public Affairs for CAA National. “Reducing these bottlenecks will increase the quality of life for millions of Canadians, save millions in fuel costs and reduce greenhouse gases, helping contribute to Canada’s climate change commitments.”

Toronto has ten bottlenecks in the top 20, Montreal five, Vancouver four and Quebec City one. Other cities such as Calgary, Edmonton, Regina, Winnipeg, Ottawa and Halifax also experience serious traffic delays.

    When Barcelona imposed an 80km/h (50mph), the result was significant in environmental, accident, fatality and injury terms. The 80km/h speed limit had the same positive environmental effect as if 22,100 cars were eliminated from the roads in the metropolitan area. Moreover, a reduction in the consumption of fuel by more than 24,000 tonnes per year was also achieved, while accidents, fatalities and injuries also showed substantial improvement.

  • Traffic to flow freely over world’s widest bridge
    November 13, 2012
    Pete Goldin reports on a new Egis project in Canada, providing open road tolling operations for the widest bridge in the world. A bridge can present a bottleneck in a system of roads or it can support the smooth and unobstructed flow of traffic. Much depends on the bridge design, surrounding infrastructure and tolling system. By adding lanes and deploying open road tolling (ORT), the new Port Mann Bridge located in the metropolitan Vancouver area in British Columbia, will alleviate congestion at one of the
