107. A lessor may, until 15 January 2019, modify the conditions of the lease of a dwelling by adding a prohibition against smoking cannabis.
To that end, the lessor must give the lessee a notice of modification describing the prohibition against smoking cannabis applicable to the use of the leased premises.
The lessee may refuse the modification for medical reasons. The lessee must do so by informing the lessor of the refusal within 30 days after receiving the notice of modification. In such a case, the lessor may apply to the Régie du logement, within 30 days after receiving the notice of refusal, for a ruling on the modification of the lease.
In the absence of a refusal, the prohibition is deemed entered in the lease 30 days after the lessee received the notice of modification.
