If such a change truly has been in place for three months now which meant that CATSA was doing a mandatory MMW scan on all US-bound passengers, I am very certain indeed that we would have heard about it here on FT as well as in the media.

That has not been the case, and I will personally consider my experience as well as the experiences of other posters over yours.
