Canadian investor looking for assistance

[Tyson Head]

Hi all, I am just looking for advice from Canadians that know the rules and regulations. I currently have two rental properties in my name and working on a slow foreclosure flip of a single family house while I live in it. I am hoping to sell the house and purchase a smaller multi family complex, somewhere between 2 and 12 units. What is the best way to protect myself from the tenants? Should I put it in a LLC, LP or something? How can I keep the tax man away from my cashflow? Is there a way to gain some benefits like vehicle write offs and things like that? Can I start a business dealing with rental properties and have the business own the multi-family complex? Wow there is so much I need to learn. Thanks for any help you can provide.
