Since you are near Toronto, you could probably get $150 for the Schwinn and $100 for the Gardin at this time of the year; add another $50 if you wait until the spring.

A few years ago I would have said that you could get a bit more for the Gardin but the market is a lot more educated about bikes now and will know that this Gardin is low-end crap and not one of the more desirable frames that were made by Joe Gardin.

I would suggest that you take the pedals off of the Gardin and sell them separately, you might get $20 for them on their own.
