Hi Louie,
In the normal course (I will qualify this below) my view is the tenants would not have any action against the EC or the OC. Their contract is with the individual owner. If they were evicted in a proper way, I can’t see what possible action they would have even against the owner.
The only possible course the tenants would have against anyone other than the owner would be if they could prove that body or person acted maliciously or dishonestly with the intent of inflicting pain on them. A very hard thing to prove in my opinion.
