While not a specific requirement under the FA, ATTs issued for regular trips for up to five years are usually reserved for people who belong to an approved shooting range.
To prove one has a licence to permit target shooting, regular trips to the gun range or club must be made, and repeated one-time ATTs would be a waste of resources.
In contrast, a gun collector under FA section 30 might transport firearms occasionally, thus a one-time ATT would make sense.
[4] "Authorizations to Transport become a condition of a licence for certain routine and lawful activities such as target shooting; taking a firearm home after a transfer; going to a gunsmith, gun show, a Canadian port of exit; or a peace officer or a Chief Firearms Officer (CFO) for verification, registration or disposal".
Effective September 2, 2015, these changes to the FA came into force meaning an ATT became a condition of a licence for the foregoing routine and lawful activities.
