In London, Ontario, pet owners must follow city animal-control requirements and provincial public-health rules to prevent rabies and other communicable diseases. This guide explains which vaccinations are commonly required or recommended for dogs and cats, who enforces vaccination-related rules in London, and practical steps to stay compliant. Where the city points to provincial health guidance, follow both municipal bylaw directions and Ontario public-health recommendations for recordkeeping, reporting bites, and obtaining vaccination certificates.

Overview of Vaccination Requirements

London's municipal rules focus on licensing, animal control, and public safety; specific vaccine mandates may be set by the Province (for example, rabies control) or required by local shelters and boarding facilities. Owners should keep up-to-date immunization records for routine vaccines (distemper/parvovirus for dogs; panleukopenia/FVRCP for cats) and immediate rabies vaccination where indicated by provincial guidance Ontario: Rabies[2].

  • Licensing often requires proof of rabies vaccination when requested by the city or shelter.
  • Veterinary vaccination certificates are the standard record; keep originals and digital copies.
  • If a bite or exposure occurs, public-health units may require immediate proof of rabies vaccination and follow-up.
