Thomas S.I agree with Greg,I would send him notice of balance due on his rent,  for rent owed, you don't carry forward back rent because someone(TRA) paid current rent on his behalf, he's still responsible to make sure his rent is current and no balance is due.If he doesn't remedy the situation or ask his TRA to come up with the funds he needs to stay in the unit, then I would proceed to file for eviction.Don't confront him by yourself, take someone with you if you have to deliver notices, And at the least I'd give him proper notice of non renewal when that comes up, even if he pays what is owed, at least then you'll have a head start in ending his tenancy.Check your local state laws for eviction proceedings, and non renewal notices.

The state can make a lot of noise and scare as many landlords that they "are gunning for them" but their legal remedies are far more limited. 

@Hansen Sin check your landlord laws for what remedies you have in this case.  

Both of these issues have since been remedied (or so I think).
