How to Identify Hidden Defects in HomesA Smart Home-Buying Guide with Arash Shakour, the Best Persian-Speaking Real Estate Broker in Montreal

What Are Hidden Defects and Why Do They Matter?

According to Section 1726 of the Quebec Civil Code, a hidden defect (latent defect) is a serious problem that:

• Makes the property unusable or significantly reduces its use

• Is not detectable through a normal inspection

• Existed at the time of sale

• Was unknown to the buyer

In contrast, visible defects are issues that a reasonable buyer could identify without expert assistance.

The Most Common Hidden Defects in Montreal Homes

Some of the most frequent hidden defects include:

• Water infiltration and moisture caused by foundation issues

• Mold growth inside walls or ceilings

• Outdated or unsafe electrical systems

• Wood rot in attics or structural areas

• Cracks or structural damage in the foundation

Identifying these issues early can save buyers from costly repairs and legal complications.

Identifying hidden defects is a critical step in the buying process, but it should always be part of a broader strategy. To better understand how to approach your purchase, explore our Montreal home buying guide.

What to Do If a Hidden Defect Is Discovered After Purchase

Quebec law protects buyers through a warranty against hidden defects, unless the property was sold explicitly without warranty. In such cases:

1. Document the defect with photos, videos, and expert reports

2. Notify the seller formally within a reasonable timeframe (usually up to six months)

3. If unresolved, legal action, price reduction, or contract cancellation may be pursued
