Hey I did some reading up about it. If you signed a lease before that you were allowed small caged pets then they cannot enforce it even in the lease expired it is still valid because it shows the landlord allowed smalle caged pets at one time so she cannot change it. The only thing is if you ever signed a lease staing no pets period they can enforce it..heres what it says
May a landlord refuse to rent to a tenant who has pets or smokes?
"Nova Scotia's tenancy legislation allows a landlord to establish reasonable rules that promote the fair distribution of services; promote the safety, comfort or welfare of tenants; or protect the landlord's property. A landlord's right to do this is established by Section 9A of the Residential Tenancies Act. Examples of rules that can be established include rules around the operation of laundry facilities, storage of hazardous materials and pets.
Rules must apply to all tenants in a fair manner and tenants must be given a copy of the rules prior to signing a lease. As well, changes in a landlord's rules can be made with four months notice to the tenant prior to the anniversary date of the lease. This allows the tenant enough time to give the landlord notice that the lease will not be renewed if the tenant does not agree with any new or amended rule.
In short, the landlord, if they meet the above requirements, can indeed restrict pets and smoking.
If a no pets and no smoking clause is written into a lease and the landlord discovers that the tenant has a pet and/or smokes in the rental unit, is this grounds for the landlord to evict the tenant?
If a no pets or no smoking clause is written into the lease, the landlord has the right to seek termination of tenancy if the tenant contravenes the lease."

If you had no complaints in the future you should be fine...I personally told mine to screw off..but Im in Ontario and here our legislation makes it illegal to deny renters with pets unless they have a valid reason meaning the pet is causing too much noise or damage.
Good Luck
