Ontario Human Rights Counsel is up there, too.The reasoning for it being a form of discrimination is that a trust fund kid with no income would be left out.

I've had tenants in the past that ran into financial issues, however, they were rational human beings.

It's human nature.

Pets are animals not human family members and should never take priory when making real life decisions.

They must care for the pet according to recommendations of the AVMA, AKC, ASPCA and Humane Society.

Check with the local humane society or pet license agency.  

I truly believe that if we sit across the table and just speak like humans and let our concerns be know that 99% of everything can be turned into a win-win if people would just listen and attempt to see it from the opposite side. 

We own 81 apartment units and provide as many appliances as is humanly possible. 

Try it without lawyers first and treat each other as human beings.  

So if it were me, I would give the tenants the benefit of the doubt.I am a car salesman by trade and student of human behavior and it sounds like these tenants have the same problem that many children do when they are not met with firm boundaries: They are doing whatever they want.As the new owner, you have the fantastic opportunity to lay down the law in a way that the current owner (who sounds like a terrible businessman) really can't (not that he would anyway).Just like a new babysitter has an opportunity to lay down the ground rules with kids who were previously unruly, you can sit down with each tenant with a properly drafted lease and have a very serious discussion.
