JROC, finally I have some feedback for you. As you see it took me 3 weeks. I bet I made more than 200 phone calls and once spent a whole day on it.
I was surprised how many people can't just say no, but instead make promises and waste your time. You need to find someone who is more or less close to you, as even companies from West Island are not interested to go to Vaudreuil/Saint-Lazare. Here are some companies in your area you shouldn't waste your time on:
NATWAL METAL - guy's name is J.C. Promised to come on Thursday 3 weeks ago, haven't heard from him since. I even went to there yard in Salaberry-de-Valleyfield to find him, met some people there, they said that's only J.C. who deals with it, he is somewhere away and they don't know his cell phone number.
JO-BER Recyclage Metaux - promised to come next day each day for more than a week, after that said their truck is broken, and looks like they won't be able to help.
I also contacted several individual towing guys, they made promises as well.
