Good morning Christian,  thanks for checking in with OREIO

If you are looking for competency and expertise in each of the following, I am not sure that a one stop shop would give you the best results.  In my humble opinion I suggest considering the following: 

• For preparing and customizing leases (residential and commercial), For Residential  Leases, you could Retain an experienced and competent Property Manager, or Property Administrator, to prepare the required Government lease with the addition of an applicable addendum. In a dispute the Residential Tenancies Act will alway prevail. For commercial leases, the same could prepare the lease, however, depending on the complexity I would advise having a lawyer review a template for use, and any customized leases prior to signing.  
• Use as a sounding board on various tenant issues and must have intimate knowledge with the Ontario RTA and related case law including N13 and N5 type cases.  I recommmend Lyon Gilbert,  Out of Court
• Represent me in the LTB where necessary, I recommend Luigi Caparelli, Gold Key Management Group,
• Initiate collections where warranted -   an experienced and competent Property Manager, Administrator.

wishing you the very best, good luck.  

Mary.
