You can do the Canadian IR on a robbie. In the US you can do the ATPL on one too.
But you still need to do a checkride on a multicrew helicopter with an IFR portion and some VFR emergencies as a qualifying flight for an unrestricted ATPL. If you don't do an IR segment on the checkride you will only get the type endorsement and restricted ATPL for "utility work only".
You can use the PPC ride for the flight test, or else book a TC inspector to conduct the flight test. You have to find someone that will rent you an aircraft though, and that someone may have an ACP (check-airman) on staff anyway. If you are handy with a 212 now, you'd probably be able to find an operator with a slow winter season that will give you a few hours for around $3000/hr. You can also do it in a sim, I think it has to be a Level B or higher.
Why don't you just get a US ATPL? That way the IR will never expire (actually there are currency requirements, but nobody outside of the US would ever figure that out).
