::::I was referring to the hyphen in "Mont-Tremblant" that's more typical in French and less in English.  I agree that the dash is appropriate in La Macaza–Mont Tremblant International Airport if we want to include the city name in the title (though it should not be spaced as it presently is, per MOS:DASH).  The official web page represents this dash using a spaced hyphen, which is a not-unusual style.
