Not a moment too soon. This news reminded me that Westjet said they would reinstate their LGA-YYZ flights in April after suspending them last fall. Considering it's April 22nd and there's nothing in their schedule for the foreseeable future, I guess that's not happening.
I had been rooting for a Porter partnership ever since Westjet announced they were refocusing on Western Canada. Now here's hoping DL starts serving YOW to take advantage of the connections Porter offers from there to Atlantic Canada.
