Mold in a Condominium Unit 

When Is a Corporation Responsible?

The Principles at the heart of a recent decision of the Ontario Superior Court could apply to Alberta – "Brasseur v. York Condominium Corporation No. 50 – again confirms the principle under which a condominium corporation may be responsible for damage (including mold) in a unit. 


In the Brasseur case, mold was found in the owner’s unit. The owner and the condominium corporation disagreed about the cause of the mold. The owner asserted that the mold was the result of inadequate repair or maintenance of the common elements by the condominium corporation (and resulting moisture in the unit).  The corporation asserted that the mold was the result of the owner’s lifestyle.

In the end, the Court concluded that the common elements (not the owner) were responsible for the mold; and the Court also held that the corporation had not acted with reasonable haste to address the cause or the resulting mold problems. The Court’s decision included the following:

…I have concluded (that) YCC 50’s overall approach to the mold problem was not reasonable. Thus, I find that YCC 50 has violated their duties as found in s. 90 of the (Condominium Act, 1998).

In summary, the Court confirmed the long-standing principle that a condominium corporation is not the “guarantor” of the common elements. The test is reasonableness, meaning that condominium corporations are obligated to take reasonable steps with reasonable haste to maintain and repair the common elements (and, in doing so, to reasonably prevent harm to the owners and the units).

What is “reasonable” will of course depend upon the particular circumstances. Some problems can take time to analyze and resolve; and the Court in the Brasseur case also acknowledged that condominium corporations are obligated to balance competing needs and priorities (which can always slow down the process).

In the end, it’s a matter of deciding whether or not the steps taken by the corporation were reasonable in all of the circumstances.

If you are a Board member grappling with this test – wondering what is “reasonable” in a particular case 

  1. Be curious and concerned. As long as you are interested and engaged as a Board member, I think that (in most cases) your decisions will be well-informed and cautious (and therefore reasonable). [In my experience, almost all condominium Directors and Managers meet this test…which of course is great news for most condominiums!]

  2. If in doubt (as to the available information or as to what to do), consider obtaining advice, input or guidance from an expert. "
