Steiner's Canada pages provides 2 spaces for the 37c smaller Parliment. In my 2016 Scott, it shows 13½x13 and 13½x14 varieties. I suspect the heading on the Steiner page is incorrect so I put the 13½x13 stamp in the 13x13½ space.
Can someone confirm the versions of the stamp?

Yes, the header is incorrect. It should read 13½x13 and 13½x14, respectively.
Technically, the 13½ should be 13.3, but Scott didn't do the decimal thing until later and hasn't bothered to go back to update all the older listings.
EDIT: sorry, please see next post for correction

My eyes are getting very bad. I only now see the middle stamp is 38¢. This is to correct my reply above.
In that case, there should be 3 different perforation headers, from left to right, respectively:
13½x13, 13x13½, and 13½x14
Using the more accurate decimals, they would be:
13.3x13.0, 13.1x13.6, and 13.3x14.0

Thanks. I figured there should be 3 headers. My only concern was there was another variety lurking somewhere in Scott.

This discussion begs the question, is the standard for listing the perforations VxH or HxV (horizontal/vertical)? I am never sure.

I believe there is a standard, paper measurements: "W" x "H" and for our stamps that translates to Top/Bottom x Sides and think that is HxV, but do not want to confuse myself :-)
This is often included as part of the introduction to a stamp catalogue and is a handy reference if you forget and need confirmation...

Perforation measurements are given in clockwise rotation, starting from the top (e.g., for rectangular stamps, top, right, bottom, left).
When the stamp sides don't have the same perforation measurement, it is said to have compound perforation.
A common type of compound perforation is when opposite sides are the same. Then the top x right perforation measurements are sufficient, as in the case of the OP.
The are a few examples of compound perforations where 3 or even all 4 sides have different perforation measurements. Again, measurement is given in clockwise rotation starting from the top.
Things get a little tricky with non-rectangular or curved stamps, the basic principle is the same -- measurements listed in clockwise rotation.

Most instructive and easy to remember! Indeed hrdoktorx and after looking at some of the Cinderellas with slogans shared in other threads here on the Forum, the mnemonic for measurements could be "H" before "V", you will never forget...(just like the alphabet) Thanks!
