Ok, quite a few people are still confused about ATTs. Hopefully this helps.
ATT: Authorization to Transport. Self explanatory, if you are moving a restricted/prohibited firearm, you need permission. If it's a non-restricted firearm, this does not apply to you in any way.
Types:
STATT: Short Term Authorization to Transport. This is a one shot deal in most cases, good for a limited time only.
Just bought a new gun at the local store? You'll need the STATT to take it to your home or place of storage. If you need one, it should be issued at the same time your transfer is completed. The STATT can often be faxed to the business, or e-mailed to a person (buyer/seller) to move things along more quickly and allow you to take your gun home ASAP. These have a limited time window as the CFO will only give you so long to go pick up your gun, usually 3-14 days. It expires on the date/time shown on the STATT, or as soon as you have arrived home with your gun. If your firearm is being shipped, you should not need an STATT as it will be carried right to your door. If you're not home and the parcel is sent to the PO for you to pick up then you are supposed to get an STATT to go get it. My opinion, mail is mail until it's opened. If you're expecting a gun, don't open the box until you get home.
You might also need an STATT to bring your gun to a gunsmith or to travel to a range you don't normally visit. In these cases you will need to apply to the CFO in advance before you intend to make this trip.
To make your life easier, before your first purchase, join a club! You may not NEED to, but everything is so much more streamlined if you have proof of membership in hand when you buy.
LTATT: Long Term Authorization to Transport. This is the ATT you use to travel from your home or place of storage to the range(s) for which you have been permitted. Some LTATTs will cover a whole province or more. Some might cover just one range. This is a matter to be dealt with between you and your CFO, as it is their sole discretion on how to issue these. If you just bought your first gun you will have to provide proof of club membership to your CFO in order to be issued an LTATT. You will also be required to show your renewed club membership to renew your LTATT. An LTATT is generally good for 1 year or for as long as your current club membership is valid, but this too may vary.
Are we clear on the two types and what they're for? There are exceptions to every rule but the above is generally how things go and I think I covered the common scenarios. Hope that helps, take a breath everyone, this is not rocket science, it's easier than you think and once you've sorted this paper-work out once it's pretty smooth sailing from there. Cheers!
Don't forget you can always call the CFC/CFO as well if you're not sure about something.
