If it happens in US, you can sue him at small claim court. It will cost you $150+/-,you have all the proof that he intentionally defrauded you. You don't need to hire lawyer but just have to present all the documents to the judge.
When you win the case he might still not pay you back,however his credit will be screwed and he will have problem getting a mortgage if he intends to purchase a property sometime down the road. The judgement lien will against him forever on his credit report.(that's how it works in US, not sure if Canadians do the same)
After all, he is too low, give him what he deserves....
