The respondent contractor was retained to construct a new home.
He performed most of the work, but the owners installed the well, septic system, and fireplaces.
The respondent was charged with failing to register as a builder under the Ontario New Home Warranties Plan Act.
He was acquitted at trial and on appeal on the basis that he was not a 'builder' because he did not perform all the work.
The Court of Appeal allowed the appeal, holding that the Act is consumer protection legislation requiring a broad interpretation.
A contractor who performs a significant portion of the construction is a 'builder' even if the owner is responsible for some work.
