Worst traffic is in Vancouver, Toronto and Ottawa
Three Canadian cities appear among North America's 10 most congested according to TomTom's first quarterly Congestion Index: Vancouver (1st in Canada, 2nd overall), Toronto (2nd in Canada, 9th overall), and Ottawa (3rd in Canada, 10th overall).
On average, daily commutes in Vancouver take 33% longer during peak congestion periods than when traffic is flowing freely. They're 65% longer during the most congested hour of the evening rush period and 51% longer during the most congested hour of the morning rush period.
The Globe and Mail reports that Vancouverites who drive at rush hour for 30 minutes a day can expect to spend an extra 83 hours a year in traffic.
Montreal fared only slightly better, placing 4th in the country and 12th overall (7th in 2011), with morning, evening and average commutes longer by 37%, 63% and 20%, respectively.
