Do I have a legal case of any sort?

My closest friend who's an accountant has been living on the opposite side of the country has been doing my taxes for me the last 5+ years. He recently got into some problems with his marriage and has been dealing with some financial problems. He asked me to lend him $2000, which I did through a bank transfer. He was originally supposed to pay me back within a week, but that week turned into two weeks and those two weeks into a month, and now it's been nearly 2 months. I also found out that he never filed my taxes for last year, and he has been ignoring me on both paying me back and looking into my taxes, subsequently I am now stuck getting an accountant locally (which is the least of my worries). The bigger problem I'm now dealing with is that this friend turns out to have borrowed a **** ton of money from others as well, and isn't getting back to them either (including his soon to be ex-wife). I am kind of worried he's trying to commit fraud and I am uneasy about this given the fact that he also happens to be an accountant and has access to all my income info from the past few years and my social insurance info... so not sure what steps to take to protect myself from any potential and in addition to that if I can legally press charges against him for not repaying the money lent. This isn't my first solution, just trying to know my options if push comes to shove with this fellow now that he's been AWOL the last week+.
