Ontario Real Estate Agreement Of Purchase And Sale Am I Obligated To Work With My Real Estate Agent?

Am I obligated to work with my real estate agent? - ontario real estate agreement of purchase and sale

I offered a quote for a home through my agent and anti. Never again to me-cons offer before it expires, and that someone is at home. I do not remember signing an exclusive agreement with her, but she made me sign the offer so many things that I do not know if I signed something.

I'm in Ontario, Canada ... Should I continue in order for a certain period of time?
