Not true at all.

the movie itself will be encoded at PAL frame rates and line sizes,

625/50 and 525/60 have virtually identical line rates, the frame rate
is different, obviously, hence my comment about the programme not
lasting as long.

whether or not a modern player is smart enough to do the conversion I do
not know.

'tis true but as far as the data on the disc is concerened it is not
PAL NTSC or anything else "analogue". It's "only" a transcoding
process from MPEG-2 to output it in any digital or analogue format
you desire.

A "PAL" disc has the video encoded with as [ 720 | 704 | 352 ] x 576
pixels 25 fps and "NTSC" one [ 720 | 704 | 352 ] x 480 29.97fps.

Not that hard to drop the 96 "extra" lines when going from "PAL" to
"NTSC" be a bit quick 'n dirty but who cares these days...

As you say easier to buy a disc in Canada, there won't be a shortage
of versions I'm sure.

Now that is a very good suggestion, it takes me out of the loop :-))
