Geez, here in the US even building management cannot come into your home without giving you prior notice and getting your permission, unless it's a matter of public safety like a gas leak. If evidence is gathered while breaking this law it is thrown out of court.
I'd check and see what the landlord/tenant laws are like in your city and province to see if you have that protection too. That way you'd have time to temporarily house your animals with a friend and avoid future trouble.
