Well, any training entity will refuse to issue an endorsement if the candidate cannot meet the practical test standards. That said, some examiners are more given to spuriously busting candidates than others. I can't speak to the specific incident in question at Bombardier, but it's possible. The good news is that there are a wide selection of training companies through which you can obtain a CRJ type rating at your experience level. I've dealt with quite a few low-to-moderate time pilots from India as well as Oz in my travels as an instructor and would-be expat.
Personally, I've got nothing but good things to say about
Pan Am International Flight Academy. I know quite a few guys who showed up on property there with less experience than you have, and the instructors busted their butts to get them up to speed for their checkrides. A CPL/ME is enough for most of their programs, I think. I believe they do most of their CRJ training out of their sims in Minneapolis. I did a 737 type rating with those guys some years back (with less experience than you have now), and found them to be great folks, and they were running a really cheap price, to boot.
