I don't wish to engage in a flame war, however, your exuberant and misplaced arrogance must be checked.
I am very familiar w/firearms tests and laws, PAL, Restricted Weapons, and ATC.
You should not draw ill informed assumptions.
In answer to your questions:
Marksmanship tests are a part of getting a firearms license in Japan and several other countries, the method of administration could vary, depending on volume, but the likely choice would be to administer the test at ranges than now offer the Canadian Firearms Safety Course.
The applicant would cover the cost of the test. Hardly complicated.

In respect of the number of guns, let's be clear CBC just did a story this morning, informed by the police that multiple valid PAL and/or Restricted Weapons license holders have been illegally dealing weapons, one person having done so 47 times.

The issue is not one of banning anything, nor of undue hardship on someone with a hobby, we could reasonably debate what number of hand guns (and I'm only discussing those, not long guns) would be reasonable for a hobbyist, but at some point, there is such a thing as an unreasonable number, and I'm certain 47 is well past it. Aside from avoiding intentional misconduct, one would have to be concerned that if someone has an arsenal of weapons at home, you will be a target for gun theft, and even a gun safe is not impregnable.

Your description of the inspection rights is
Incorrect:
The Firearms Act provides that a firearms officer may inspect any premises where there is suspicion of more than 10 guns existing.
Who can do this and how can it be done? Who can enter to inspect? This is a firearms officer only (no other officers or helpers). Under C-68, firearms officers are restricted to designated offices. Not every police officer is a firearms officer. At the present time this should include your local firearms officer who assists in issuing transport permits and registration applications for restricted firearms. In Ontario there are less than 200 such officers. This number may shrink considerably.
The procedure is begun by a firearms officer contacting you to arrange for a date and time to inspect. You are obligated to make the arrangement within a reasonable time. That is when the firearms officer contacts you, you get back to him or her in a reasonable time to set the appointment some time in the future when it is convenient for both of you. Then the officer will attend and inspect your building. If you consent to this, the officer can stay until you revoke consent or until he/she is finished.
