FWIW, I recall reading that the program in Canada is reciprocal, and it is simply the case that Canada hasn't decided to operate any corresponding facility in the US.
That is correct. IIRC, Bermuda is also part of the agreement, and I would be very much surprised if Ireland doesn't operate on the same rules.
