It's a good time to book airfare in Canada, with rival airlines Air Canada and WestJet offering competing promotions in a bid to win over consumers.

Air Canada on Tuesday dropped its prices on select routes to $11 one-way to match bargain prices offered by rival airline WestJet, said Peter Fitzpatrick, a spokesman for Montreal-based Air Canada.

On Tuesday only, an $11 ticket could be bought for flights between Toronto, Ottawa and Montreal

"It was WestJet who put out an announcement two days ago announcing they were going to do it and typically what we do is we do match," Fitzpatrick said. "We always say we will remain competitive in all the markets we fly."

WestJet has also dropped its prices to $29-$49 on select routes, which Air Canada is also matching, Fitzpatrick said.

"Airlines do this from time to time just to stimulate a little business and that kind of thing so it's not that unusual — although $11 is a pretty good discount," Fitzpatrick said.

Last week, WestJet announced it was increasing its Vancouver to Toronto service, after competing airline Harmony Airways announced it was closing down.

Harmony Airways, based in Richmond, B.C., announced at the end of March they planned to shut down their operations because of rising costs and fierce competition.
