Unfortunately, the ad hoc definition of "settling with power" as a purely power phenomina is not correct, in Canada or elsewhere. The idea that such a definition is needed for "an approach where insufficient power is available" is right on, but settling with power is not the term.

XNR, do you have a reference to a publication of the Canadian usage of settling with power for a purely power problem?
Evidence of the confusion caused by misuse of the terms is shown by the confusion about recirculation, which is the cause of VRS/Power settling/settling with power. It is the recirculation of the downwash that causes all the misery of VRS.
We should actually agree on a term for the falling through on an approach that is caused by insufficient power, and stick to it.
Otherwise, we should declare this thread to be "Condition Alpha" and simply re-run it every 3 months, which is about how long it takes PPRUNE to forget the last time we all tossed this ball around!
