Good for WS, and good for SU employees who will be flown by a company dedicated to the business of flying people around, a well-known Canadian brand name. Rather than Suncor's internal airline which, due to scale, may be harder to staff, train, and maintain overall professionalism than seen at WS.
With the tragic events at YMM with the fires, more uplift was probably required as well. Over the long term, SU should be working towards eliminating out-of-town commuting, but until then, WS is a great company to be serving their needs.
