Toronto's Pearson International Airport has been named the worst airport in Canada, according to a new survey from online travel agent FlightNetwork.com.

Of Canadians surveyed in FlightNetwork's online poll, 37% of respondents said Pearson was the worst airport in Canada. This is up from 28% of votes received during FlightNetwork's 2010 version of the survey.

Montreal's Pierre Elliott Trudeau Airport was named second worst by 18% of Canadians, while Edmonton International placed third with 10% of votes.

Fifty-seven per cent of Canadians said slow security was what made Pearson worst in their eyes. The airport also received poor marks from Canadian travellers for bad service and a lack of good dining options.

Vancouver International was named the best airport in Canada, with 35% of votes.

Internationally, London Heathrow was named worst in the world with 26% of travellers' votes. Toronto Pearson ranked third in the international rankings with 13% of global votes, while Paris' Charles de Gaulle was second.
