Transfer certificate or Registration needed for transport?

[IJ22]

The CFO's office routinely send ATTs via email.
Maybe they can send registration certificates by email, although I've not heard of anyone getting one.

Sure, I get my Notification of Transfer by email all the time.

The difficulty I have with being told I must keep my gun at home is that there is nothing in the law that creates an exemption for being in possession of a restricted firearm without a registration certificate as long as I just bought it and brought it home while I wait for a registration certificate. The way I see it, the NoT either IS a registration certificate, or it IS NOT a registration certificate. It's binary, there is no grey area. You're either fine taking your gun to the range, or you're already breaking the law by having brought your gun home. The CFP and CFO have a lot of discretionary powers, but inventing conditional registration certificates is not one of them.

I'm not going to bother digging one up now, but I'm pretty sure even the NoT says "you may now take possession....". It doesn't say you can only bring it home, and why would it, it's a possession document, not a transport document.

The NoT is not a registration certificate.

The question is whether the NoT, which has the registration certificate number on it, is proof that you are the "holder" of a registration certificate.
Since in order to have a registration certificate number you must have a registration certificate in the CFRO database. The number is proof of, and the index to, a valid registration certificate for you and that gun (thus you are the holder in that sense), you just don't have it in your hand yet (which is holder in another sense).

The next question is if you can convince a cop of that, and then if you can convince a court of that.
It's probably cheaper & easier to wait.
