You need a bit more detail about what the Owners Corporation have done. In what form were the orders to the Owner? If the Owners Corporation have issued a Notice to Comply with a By-law then it can be followed up with a fine imposed on the Owner for a continuing breach of the By-law. The OC cannot evict a tenant, as leases are between the Owner and Tenant, in this case it may just be an informal arrangement between father and son. As we’ve said before in this forum, notices need to be formally issued and there really is only a need for the one notice, successive letters on the same subject only indicate to the recipient that there is a lack of resolve by the Executive Committee and or Managing Agent to follow up.
