CF-xxx vs. C-Fxxx

(note
that Canada is missing the CG... probably a typo).

Not a typo. It lists C and CF as prefixes. C is the current style, and
CF the old style still on many airplanes.

It gets converted to C-FXXX upon repaint...

Not necessarily. Aircraft built before some cutoff date (1974?) may keep
the CF-XXX style of registration if they wish. I think that you still
appear in the TC database as C-FXXX.

Here's what CAR 202.03 says:

202.03 (1) Subject to subsection (2), the nationality mark in respect
of a Canadian aircraft is the letter "C" and the registration mark in
respect of the aircraft is a combination of four letters specified by
the Minister.
(2) Subject to subsection (3), where an aircraft was registered in
Canada before January 1, 1974 or is a vintage aircraft,
(a) the nationality mark in respect of the aircraft is the letters "CF"
and the registration mark in respect of the aircraft is a combination
of three letters specified by the Minister; or
(b) the nationality mark in respect of the aircraft is the letter "C"
and the registration mark in respect of the aircraft is a combination
of four letters specified by the Minister.
(3) Where the owner of an aircraft, other than a vintage aircraft, that
has the letters "CF" as its nationality mark and a combination of three
letters as its registration mark repaints the aircraft, the owner
shall, prior to operating the aircraft, change the nationality mark to
the letter "C" and the registration mark to the letter "F" followed by
the combination of three letters.
(4) Where the owner of an aircraft changes its marks pursuant to
subsection (3) or the owner of a vintage aircraft changes its
nationality mark from "C" to "CF" or from "CF" to "C", followed by the
appropriate registration mark, the owner shall, prior to operating the
aircraft, notify the Minister in writing of the change, and the
Minister shall change the marks accordingly in the Canadian Civil
Aircraft Register and issue a new registration certificate to reflect
the change.

According to section (3), vintage aircraft can keep the old marks.
Here's their definition of vintage:

"vintage aircraft" - means an aircraft that was manufactured prior to
January 1, 1957. (CAR 200.01)

You were right: there are exceptions for old airplanes. There are
still compassionate people in government!

Generally in any base base 10. Base 36 for instance uses the digits 0
to Z - so every letter of the alphabet is a number.

Hex is very common (0-F), but we do have one system that uses base 36.
Base 64 encoding is also common (in which case 'a' is a different number
to 'A')

In the base that Canada uses for aircraft registration, when are letters
numbers?

That wasn't the question you asked.

Context.

Steve, ya screwed up asking the question. You can't be the invincible SPMc
without admitting a typing lapse, can ya?

Either admit to a lapse in questioning or affirm your claim to
infallibility. Your choice. You COULD possibly be elected the next Pope.

Lapse in questioning? Upon reviewing the thread the question still makes
perfect sense, unless one ignores the context in which it was asked. Could
you cite this "claim to infallibility", I don't recall making any such
claim.

Great. Another Wisconsin Pope.

All of them, as previously explained.

(As an aside to all the pedantry that's bouncing around this thread, I
think you must realise that 'numbers' is just an American figure of
speech; after all, in the US plane registrations are colloquially known
as 'N numbers', even though quite frequently the last one or two digits
is a letter, and is probably not intended to be base 36! In most other
countries, we just colloquially know our registrations as 'G-reg' or
'D-reg' or.. etc. without even mentioning the word 'numbers'. In this
part of the world, car registration plates are colloquially known as 'number
plates' even though they don't just have numbers, well, unless you live
in Guernsey).
