Who do you ask for Olympic approval?
What you have to do is set out in section 43 of of Bill C-21 which adds new section 97.1 to the Firearms Act. This section 97.1 creates exceptions to the handgun transfer ban set out earlier in the Act. The Olympic/Paralympic exception is in para (b). You have to get a letter from a provincial or national sport shooting governing body. Nationally, that'll be the Shooting Federation of Canada, which governs Olympic and Paralympic shooting in Canada. Provincially, it'll be whatever organization is the SFC's counterpart in your province. This section does NOT say that you have to be an Olympic level shooter. What it does say (and what the letter has to say on your behalf) is that you have to be training, competing, or coaching in an Olympic or Paralympic handgun shooting discipline. Many local clubs have leagues that do this type of shooting. You do NOT have to be an elite competitor. If you can hit an 18" one-ring at 20 yards, one handed, with a 5 shot 22LR handgun, you can score in competition. (Needless to say, the 10-ring is quite a bit smaller.) Presumably you'd have to be able to show that you are actually doing the discipline regularly to get the required letter out of the governing body. In my league, a number of new shooters who don't yet own a pistol are competing with pistols borrowed from other club members, to build a record in order to support a future request to the governing body for a letter that will enable them to buy a competition pistol of their own.
The wording of the section is:
Exception — handguns
97.#1 Sections 12.#2 and 19.#1 do not apply in respect of an individual who
(a) holds an authorization to carry in respect of a handgun; or
(b) meets the prescribed criteria and annually provides a letter to a chief firearms officer from a provincial or national sport shooting governing body indicating
(i) that they are training, competing or coaching in a handgun shooting discipline that is on the programme of the International Olympic Committee or the International Paralympic Committee,
(ii) the disciplines in which they train, compete or coach, and
(iii) that the handgun in question is necessary for training, competing or coaching in those disciplines.
