Looking at the Library Catalogue may answer your question. However, the Provincial Library of the Ontario Genealogical Society also has volunteers who can help you use our library collection.

The Ontario Genealogical Society does not do detailed genealogical research. For that you should hire a professional genealogist. We do not make recommendations - we suggest that you visit the website of the Ontario Chapter of the Association of Professional Genealogists.
It is wise, especially when working with a researcher for the first time, to agree on the work and the payment in advance. Family history research is an open-ended task, and finding a simple fact can take a lot of research time. Professional genealogists can advise on how much particular searches may cost, and how long they may take. Be clear about your limits both in how much you want and what you will pay. Different researchers may have different fees, and different work loads.
