FidelFidel,When I saw your question I got interested as most Canadian investors are rather running away (or pausing) from investing in RE in Canada.But to help in your journey, here's what I can share mostly from either my personal experience or discussion with relevant professionals. 

Thanks for sharing, the POA to access the original docs is a great idea, and I'm totally stealing it for the future. 

I hope with this extra info you can see more clear my current and future goals. 

I could care less if someone smokes marijuana but worried it might impact other tenants & future renters.What are my options, if any?

Although i do think there is more money to be made in RE than selling soap. 

It avoids having to pay the capital gains and lets the property keep appreciating while you still own it and reap those future rewards and more cash-flow from the property in the meantime.  

With hopes to build two additional cabins in the future.

Additionally, I'm banking on a future opportunity to refinance.After less than a year, here are a few tips from what I’ve learned:*Hire a local STR expert real estate agent to guide your investment location.

Repairs made while the property is your primary residence are not deductible, but improvements can increase your cost basis, reducing future capital gains tax when you sell.

Another throws around the made up terms like “snowball” and “infinite” as if they have some magical power to rewrite the rules of finance.
