Bought something on classifieds and never received.

[Unit 5302]

Contact the post office/postmaster general. Since you're in Canada, I can't imagine you used a US postal money order. If you did, it's now felony mail fraud. Regardless, contact the money order issuer and see what they advise you in terms of their fraud protection policies. If they do, they will go after the thief, and believe me, they want their money back, and they know how to get it back.

If I had been screwed out of $1,150, I would post it everywhere I could for multiple reasons. First, I want to make their life hell, and second, other people that might try to buy things from the thief later should know that they'll get ripped off too.
