According to Article 1726 of the Civil Code of Quebec, a hidden defect is a flaw that makes a property unfit for the purpose for which it was intended or that reduces its usefulness so much that the buyer would not have purchased it, or would not have paid the same price, had they known about it. For a defect to be considered a hidden defect, four criteria must be met:
The defect must be serious : It must make the property unfit for its intended use or significantly reduce its utility.
The defect must be hidden : It must not be apparent and cannot be discovered by a careful and diligent examination.
The defect must be unknown to the buyer : The buyer must not have been informed of the defect at the time of the sale.
The defect must have existed prior to the sale : The flaw must have been present at the time of the transaction.
Common examples of hidden defects include water infiltration in the basement, foundation problems, hidden mold, or major roof defects.
It is important to note that regular repairs and normal maintenance of a property are not considered hidden defects. For example, replacing a roof after 25 to 30 years or windows after 40 years is generally expected and does not constitute a hidden defect.
In case of discovering a hidden defect, the buyer has a prescription period of three years from the discovery of the defect to take legal action against the seller. It is recommended to consult a legal professional for advice tailored to your specific situation.
