What ServDog is
ServDog is a private registry. It is not a government agency, is not affiliated with any provincial program, the Canadian Transportation Agency, or the ADA, and registration does not create or confer any legal rights.
- Registration as a service dog is not required under the ADA.
- Nothing we issue conveys rights.
- The ADA requires no certificate.
- We do not sell clinician letters.
