Aberdeen first debuted on the top regional list for Hamilton in 2021 and moved onto the provincial list in 2023.
In second and third place are Barton St. E. in Hamilton and County Road 49 in Prince Edward County, two roads that previously appeared on the CAA Worst Roads Top 10 list six and seven times, respectively. Both roads are expected to receive significant upgrades.
Making the Top 10 cut from Toronto is Eglinton Ave. W. at four, the Gardiner Expressway at nine and Sheppard Ave. W. at No. ten.
“Timely repairs, better communication, quick fixes, pothole funds, and using recycled aggregates are just some solutions to fix unsafe roads,” says Teresa Di Felice, assistant vice-president of government and community relations, CAA South Central Ontario.
“CAA continues to urge all levels of government to prioritize road safety with stable funding to do so.”
This year, participants nominated more than 2,400 different roads from 208 municipalities, up from 2,000 roads from 145 municipalities in 2024 – a 20% increase in roads nominated and a 42% increase in the number of municipalities with roads nominated.
“For over two decades, the CAA Worst Roads campaign has given Ontarians a voice to spotlight unsafe roads in their communities and push for much-needed repairs,” Di Felice said in a statement.
“This list provides a powerful snapshot to governments on where to prioritize budgets and move up road repairs, and we know that the public supports these efforts.”
CAA research shows that 26% of survey respondents were dissatisfied with road work projects because they take multiple seasons to complete. However, 85% are willing to put up with the inconvenience of construction in exchange for long-term improvements.
Ontarians shared their primary reasons for selecting a road, with 84% citing potholes, followed by poor road maintenance (77%) and traffic congestion (15%).
