TORONTO — Porter Airlines CEO Robert Deluce said an IPO “probably makes sense in the mid-term” and hinted that the carrier could be looking to expand in the Montreal, Halifax and Ottawa markets.

Deluce didn’t offer specifics but he didn’t rule out a second run at an IPO, according to BNN. Porter was gearing up to go public in 2010 but the economic downturn put the brakes on those plans. Now, he says, “even though we don’t require additional funding now, in the future … it would be an additional opportunity for us to consider our growth plan.”

News about expansion plans in Ottawa, Halifax and Montreal could come by the end of this year.
