Long story short. There were three bidders, Leonardo with C27J, Embraer with KC390, and Airbus with C295W. Contract is not only for aircraft but also infrastructure, maintenance support, and training. Contract includes extensive industrial and technological trade benefits. There are major Canadian sub-contractors involved, like PAL, P&W, and CAE.
All potential providers had the opportunity to consider the requirements, submit feedback, and submit bids. We can discuss our favourite FWSAR contenders all we want, but if they did not enter a bid, they weren't considered in the final assessment.
As a retired FWSAR pilot, I am most appreciative the gov't made a decision replacing the aged CC115 Buffalo and CC130H fleets as opposed to dragging out this procurement process like many others.
