Quebec residents appear to be among the least susceptible to cyber crime while citizens of Burlington, Ont., were the most susceptible in a list of Canada’s most vulnerable big cities, according to a report by security soft­ware maker Symantec.

The company used recorded incidents of cyber crime and per capita data on Internet access and computer spending to determine which of Canada’s 50 largest cities rank most at risk for online threats like identity fraud.

Burlington was ranked the most vulnerable overall with the most incidents of security incidents, per capita, in three of four threat categories.

Burlington had the worst rates of computers infected by malware programs, attempted infections, and rates of computers being hijacked to send out spam.

Burlington was second worst behind Victoria, B.C., in the fourth category — having a computer co-opted into a so-called botnet, a global network of computers that carries out attacks.

Symantec says higher per capita access to the Internet — through home connections and WiFi hotspots — increases the risk of a city’s computers being targeted.

The affluent Ontario suburb of Oakville was ranked as the sixth most vulnerable because of high rates of Internet access and computer spending, even though the city was 25th in incidents of cyber crimes.

Montreal had the highest ranking of Quebec cities on the list, at No. 25
