I haven't used their services, but a few years ago I bought a car from a dealer that had a bad head gasket, there was a number in the Blue Pages where you can call can make an appointment with a lawyer for like $20 and they give you a bit of legal advice. I don't know what that is anymore, a quick google search provided me with this:
Dial-A-Law
Also, for further FREE legal advice, you can meet with a UBC Law student here:
Law Students' Legal Advice Program
From their website :
"
LSLAP assists low-income earners with various legal issues, including:
Criminal;
Small Claims; "
IMHO, for something like this I think LSLAP should suffice. Once again, good luck!
