What is the standard of care of a contractor in a residential renovation?

British Columbia, Canada

The following excerpt is from Johnson v. Flaig,, 2020 BCCRT 407 (CanLII):

24. Often in claims of professional negligence, an applicant must establish a breach of the standard of care through expert opinion evidence (Bergen v. Guliker, 2015 BCCA 283). In the circumstances here, I find expert evidence is not required to establish the standard of care. I find the standard of care is that of a reasonably prudent renovation contractor taking reasonable care not to cause of a flood. The contractor does not dispute that he caused the flood.
