434.This section sets out restrictions on the exercise of the landlord’s power to obtain possession on the ground in section 190. If the landlord seeks possession on this ground, the landlord must give the contract-holder a possession notice specifying the ground within two months of the date the contract-holder was due to give up possession. The landlord may make a possession claim from the day the possession notice is given to the contract-holder, but not more than six months after that day.
