I share your sentiments
STC, but the ERJ-190 (and -170) are new designs. Don't know if Embraer has any plans to get a Canadian TC for either, but I'm not convinced the hurdles are as great as you suggest. There's an executive Dornier 328 in Calgary which
AFAIK is the only one in Canada, so I assume its operator did not find certification a problem since there are several comparable alternative types.
As to the quality of the rear-engined ERJs they certainly look flimsy beside a CRJ, and I don't know of a CRJ that has broken its back on landing.
So what
did happen to those ERJs at Dorval ?
