I would say that this is question of semantics.
Does BBD have plans to offer / develop (or at least consider offering) the CS500 at some point in the future? Almost certainly. BBD has clearly had the thought that the CSeries (once successfully established) could potentially grow into a larger market segment.
Are they working on it actively (or could they) at this moment? Not so much.

I wonder though (and certainly no expert on Canadian P&T law), wouldn't BBD have a fairly strong case there in that it clearly is part of a family and the attempt just a try to cash in? If you had a product or service using that mark I'd buy it, but someone just laying claim to the "CS700" title would be a blatant patent troll I'd think.
I'm not an IP law specialist, but my understanding is that BBD would still have an opportunity to oppose any attempt by a "trademark squatter" to trademark CS500 for aviation - and that they should succeed if they can show that they used the term prior to the date of first application (for the particular industry in Canada).... as long as the applicant didn't have a prior use in the same industry.
As long as they (or their counsel) are paying attention to published trademark applications, they should be safe enough.
