Domino is in Canada, and with the American government's actions on the borders, I'm pretty sure travel became a blippin' nightmare. At one point Domino could not re-enter the US for weeks returning from a vacation in Canada,and that was even before the current administration.
I think that was just an easy excuse, not the real reason. I will have to admit, I was not always a fan of Domino - but boy do I love Domino now that I see what we get instead.
