1) How is it that two supposedly independent third-party grading
companies chose nearly identical (and very different from those of
U.S. TPGs) packaging formats?

Beats me.

2) Wouldn't it be relatively easy to fake such packaging? I'm
thinking that there have to be items such as 1921 Canadian 50c pieces
and Newfoundland 1873H 5-cent pieces residing in them.

All packaging is relatively easy to fake, although the flips used by
ICCS & CCCS seem to be especially vunerable.

3) Have any fakes of these packages been confirmed?

If they have, it hasn't been reported by Canadian Coin News or the RCNA.
