Griffons are unarmored, unarmed (besides side-mounted guns, which were retrofitted following feedback from Afghanistan) and don't fare well with the dirt and heat (again, they were modified following their initial deployment to Afghanistan). They are effective as support helicopters, but as combat/special operations deployment platforms... they hold their own, but have their limits. our new Chinooks do great what they were designed for.
As far as fixed-wings goes, the CC130J recently acquired, while more sophisticated, are also less rugged than the Hotels. They don't have navigators which, while it might makes things easier for boring freight missions or mid/high altitude drops, sucks for low-altitude tasks like SAR... or special operations. Which is why end-users are pushing for new planes, more specifically the C-27J (as Hotels, while more appropriate than Juliets for their ops, are getting old and need lots of maintenance for every flight hour). But paper-pushers (especially the government... while the Conservative govt is more supportive of the armed forces than past Liberals, they also are cutting expenses where they can, which includes equipement purchases.) Reviving & upgrading the Buffalo is also an option which many are pushing for as it'd be a Canadian-made option... but to be honest, it's an inferior aircraft though politicians might prefer it.
Note that many of the links below specifically mention SAR (possibly one of the most if not THE most active taskings for CF aircraft), but lots of it also applies to CSAR and SO.

Not an expert though so feel free to do your own readings... but that gives you an overview of the situation.
