Oh Saab is throwing everything at the Canadian requirement because they think there is a chance to get a sale to either replace or supplement the Canadian F-35 buy. I don't think they will be successful and have been hearing murmurings confirming that from within the Canadian Govt. The Canadians have already committed to at least 30 F-35As (two orders - 16 & 14). The first of these is expected to arrive this year. Their industry is already well involved in the program producing parts on all F-35s, not just any Canadian ones. This is obviously a politically sensitive subject for the Canadian Govt, especially the rhetoric coming from the South, though the fact that the second F-35 order was made (albeit quietly) only in February this year, I think we can see where things are going.I don't know how reliable this one is....
Saab seeks partnership with Canada on next-generation fighter development
I don't blame Saab for their trying to get in there as a Canadian buy would be a massive win for them. They are therefore throwing a lot on all fronts at this. However, even going for a dual type fleet (F-35s and Gripens) would be an even worse (and expensive from sustainment perspective) outcome. It is also interesting that only Saab seems to be trying to get in here. If others really thought that there was a chance to upset the F-35 buy than you should see Typhoon (a better choice for Canada I feel) or Rafale being pushed but there is nothing on these fronts.
