The fleet that's being replaced, the CC-150s, were originally Wardair A310-300s four of which were converted to combi-freighters. The CC-150Ts were upgraded from the later for two-point hose and drogue refuelling and a new mission suite.

Support for allies leads me to the question of refuelling systems. Although the A330 MRTT usually comes with a boom, I wonder if a perceived lack of a domestic requirement means:
1) The fancy new KC-46 boom isn't required.
2) The Bug replacement is expected to be probe equiped with implications for the F-35 as a participant in the selection competition
Mind you its probably non-fuel payload and passenger capacity requirements that were the real deciders. Especially if the fleet split is like for like.
The article linked to by the OP states that Ottawa 'will outline the specific capabilities needed. An RFP (request for proposal) is expected to be issued later this year.' An RFP when you are down to one supplier and one basic product...hmmm.
