Deficient service claims cover a wide range of situations: a repair that does not fix the problem, construction work that falls short of specification, or a professional service that was not delivered as agreed.
What deficiency means
Provincial consumer protection legislation generally defines deficiency as a shortcoming, imperfection or inadequacy in the quality, nature or manner of performance required to be maintained under a contract or applicable standard.
Documenting the shortfall
- The original agreement or scope of work, written wherever possible
- Photographs or records of the deficient work or outcome
- Correspondence raising the issue with the provider
- Any quotation obtained for correcting the deficiency, where relevant
Distinguishing a genuine dispute from ordinary dissatisfaction
Not every disappointing outcome is a legal deficiency — the claim is strongest where the service clearly fell short of what was specifically agreed or of an objectively reasonable standard, not merely where the outcome was not what the customer hoped for.
What to do next
Bring the agreement or scope of work, evidence of the shortfall, and a record of your complaint to the provider.
