Damp, condensation and heating: what a landlord must fix in Quebec
Condensation on windows, mould in a corner, a dwelling that will not warm up: three different problems with three different duties. How to tell them apart before claiming.

Dated evidence beats a long story
Most dampness disputes are lost on proof. A thermometer, the same photo angles and a short written notice to the landlord do more than any argument about what is suspected.
Three problems, three responsibilities
Water entering from the building (roof, foundation, window joint, pipe) is a defect the landlord must fix. Moisture produced inside with nowhere to go (no bathroom fan, dryer in a closed space) raises the question of who must provide ventilation. A dwelling that cannot be heated to a reasonable temperature is documented with morning and evening readings on cold days.
What a tenant can require
Report in writing, allow a reasonable delay, document the consequence (health, damaged property, lost use of a room), and keep every reply. Then choose the right remedy: ordered repairs, a rent reduction, or leaving a dwelling unfit for habitation.
When it becomes a health issue
Mould in the room where a child sleeps, a persistent smell, coughing only at home: do not wait for the next inspection round. The evidence expected and the Tribunal administratif du logement process are set out in the unhealthy-dwelling page.
