You can search for an Ontario non-profit corporation using the Ontario Business Registry (OBR). Here is a link to the OBR. Once you click the link you will need to scroll down and click on the blue icon that says “Search the Ontario Business Registry“.
Before the public availability of this registry, the only public list of Ontario non-profits was here.
If your Ontario non-profit corporation needs any assistance with changes as a result of the launch of the OBR and ONCA please contact us and we can be retained to assist. We have extensive resources on the Ontario Not-for-Profit Corporations Act (“ONCA”) for groups who wish to bring their non-profit into alignment with ONCA and also groups who wish to move their Ontario non-profits to the Federal Canada Not-for-profit Corporations Act (“CNCA”). Also, we have courses that might be helpful.
