Charity and non-profit law for organisations across Ontario, from a lawyer who spent a decade as counsel to Canada's charitable sector.
Book a ConsultationIf your charity or non-profit has not yet transitioned to the Ontario Not-for-Profit Corporations Act (ONCA), doing so is essential to maintaining your legal status. The process involves reviewing your existing letters patent or articles, drafting new articles of amendment, updating your bylaws to meet ONCA governance requirements, and filing with the Ontario government. Barry has guided dozens of organizations through this transition, from small community nonprofits in Peterborough to large national charities, and can help you navigate each step with confidence. Not sure where your organisation stands? An ONCA compliance audit settles the question.
