TORONTO - It's a top-20 list few provinces would want to be on.

The Canadian Automobile Association has released a report that ranks four stretches of British Columbia roadway -- all in Vancouver -- among the worst traffic bottlenecks in the country.

They include sections of Granville and West Georgia streets, as well as the George Massey Tunnel, which connects Richmond and Delta below the Fraser River.

Toronto dominates the rankings, taking up half of the 20 top spots, followed by Montreal, which clinched five.

The CAA report says the top 20 were found in just four cities -- Toronto, Montreal, Vancouver and Quebec City.
