As a side bar:
As of December 1 , thereis a bilateral agreement between Canada and the U.S.A .
To convert a Canadian ATPL-A to an FAA ATPL-A only requires writing a diferences exam and having an FAA medical, the same applies for the FAA to Canadian conversion.
However : It only applies to fixed wing. In Canada a type rating is required for each helicopter type and in order to be issued an ATPL-H a check ride must be done on an aircraft requireing 2 crew as per the aircraft AFM.
But it is progress.
Whether you fly an ILS approach in the UK, CANADA or Italy; whether you do an auto in Norway, Sweden, or Argentina : The procedures are identical, I simple air regs exam ( in the perfect world) should be all that is required.
