My contractor stopped working and disappeared, and I already made full payment

I hired a contractor to do interior and exterior renovation of my house back in June. I made a total payment of $63000 for the labor costs over the period of a few months.

While the renovation was supposed to be finished at the end of September, the contractor kept asking for more time every time the finish date came, and I had no choice but to give him more time.

Early November, the contractor demanded that I pay him $7000 for extra services he had apparently provided, which I had never asked for, and for which I was never consulsted about their price. The day I refused to pay him, he halted the renovation, sent all the workers home, and stopped showing up the following days.

I eventually ended up agreeing to pay him $7000 - $4000 upon finishing the interior, and $3000 upon finishing the exterior. - we both signed a new contract for this.

But because I felt and knew my contractor was not doing his job properly - for instance, I could clearly tell the bathroom tiles on the wall were not straight and water was not properly draining - I paid another reputable contractor to come to my place and check over the renovation progress while my contractor was not there.

The contractor went over every little details with me, and there were A LOT of problems both exterior and interior. I would basically have to redo the exterior ENTIRELY, and the repair cost for the interior will be also substantial.

When I informed my contractor about this the next day, he said he understood. The next day, however, he didn't show up, and hasn't been showing up since then. He has been deliberately ignoring my phone calls.

I sent him emails to inform him I will be taking legal actions against him if he does not resume renovation, which he read after a few hours (I can check if someone has read my email or not).

Then, when I sent him another email telling him to pick up his equipment left on my property, I immediately got an email saying that the email does not exist anymore.

I've been living at this construction site with a blanket and a pillow since October since I can't afford to live somewhere else, and my daughters have been staying over at their friends' places. I really need help.

So my questions are:

1) Can I file a criminal complaint for a fraud in this case?

2) How can I even sue him if I can't reach him? I don't know his current address. (I know his phone number, lincense number, car plate number, previous address)

3) Can I hire a new contractor to work on my place before my contract ends? The contract is supposed to end on November 31st for the interior and December 15th for the exterior.

4) What can I do about the equipment and tools he left at my place? Again, I can't give him a notice before removing them from my property since I do not know his address, and I cannot reach him!
