Porter’s radio buy seems to be as big as its print buy these days, as the regional airline once again remains in the top three radio advertising spenders in Montreal and Toronto, for the week of May 31 to June 6, 2010.

Porter, which topped the list for the week of May 17 to 23, hit #1 last week in Toronto after dropping to #2 the week prior. In the #2 slot was Spence Diamonds, a local advertiser that has been blitzing transit shelters as well as radio for several months now. And in #3, McDonald’s, heating up their summer media buy.

In Montreal, Hydro Quebec was in #1, Alarm Force in #2 and Porter Airlines rounded out the top three. The fastest movers on the list were electronics retailer Dumoulin and Corbeil Appliances, who appeared in the rankings at #8 (up from #91) and #10 (new to the list) respectively.
