With new regulations in Canada like the flipping tax and property gains tax, I want to be mindful of the risks involved. 

It is also the seller's fault for accepting it, they full well knew this was not right.If you were to file for eviction for non-payment of rent, you'd probably win.

Is there some other way to verify his involvement? 

How many 70+ year old landlords are going to be smacked with a multi million dollar fine for not filing for the last 2 years??

Should I file suit to make them sell the property?

I am able to do majority of the work involved and have been in trades for over ten years.

I strongly recommend getting involved with your local REI meetup groups so you can work out your pitch with help from other landlords.I hope this doesn't come off the wrong way without tone or facial expressions behind it. 

Then the compile everything at year end and file taxes.

Loan officers with 25 years of experience typically are more experienced, and have less time per file, because they have an abundance of files.Loan officers with 25 months of experience typically are less experienced, but have more time to devote to you.I can't write my own loans, so when I'm getting a loan I prefer working with less busy people when I'm doing my own real estate investment, they're more responsive and dedicated it feels like.

These are good attorneys, one of them even spent over 45 minutes on the phone talking to me about options, as well as a personal discussion about fishing, so he clearly wasn't trying to dismiss me.If you have a case, you can file a complaint with the state commission.
