Yes a leaking vapor canister can cause a vacuum leak code. It was off because you reset the code but the issue was still present and the car did a drive cycle which is generally 250 miles before it throws the code. Most computers look for the issue twice before throwing the light on. Purge valves sometimes on the canister sometimes not. Inspect all your rubber vacuum hoses and pressure test or smoke test if you have a leak.

Have the codes pulled and see if it was a code for the fuel canister purge control, without that code you stabbing in the dark, it could be something altogether different.
