MONTREAL — Along the back wall of a sleek new souvenir and magazine shop at Trudeau International Airport in Montreal there is an array of sports team products: jerseys, hats, coffee mugs and the like.
The logos on the items were for only two teams, the Canadiens, Montreal’s iconic N.H.L. franchise, and the Expos, a baseball team that has not existed for more than a decade.
But over the past three years, and in particular the last several months, a series of events have led people in Montreal to embrace the idea that baseball might be coming back.
