Commercial use of a dwelling sends a landlord’s insurance skyrocketing

A dwelling must not be used for commercial purposes unless specified otherwise in the lease, even when the activity in question is as valuable as an Autism Spectrum Disorder Integration Centre (Centre d’intégration pour personnes ayant des troubles du spectre de l’autisme). Not only is this a change of use of the dwelling, but the renewal of the building's insurance coverage considers this commercial activity which was not noted in the lease or in the previous insurance coverage. The Court ruled that this situation caused serious prejudice to the landlord, who suffered a significant increase in insurance costs.
