I hate to say it but I don't think Air Canada's decision was fueled by such common sense thinking as not putting all your eggs in one basket. Unfortunately it probably boiled down to keeping the two pilot groups (alpa and acpa) happy. Give the CRJ's to Jazz and the Emb to Mainline. Of course thats all in arbitration right now so nobody really knows for sure. It's interesting how the order was split right down the middle. 45 from each manufacturer.
