Where can I find moms and dads from Canada to fill out my survey for school?

I’m doing a marketing research project for my post-grad program and I need to get responses from 250 Canadian moms, dads, and busy people who cook for themselves. I’ve contacted a few sites but I don’t think it will be enough.

Any ideas where I can try posting a link to it to get some responses? If someone wants to see what it looks like I’ll post the link, but I wasn’t sure if that was allowed so I haven’t included it.
