Denis has been providing critical advice to trade unions and their members in complex labour situations for more than 26 years. His ability to analyze an issue from various angles and anticipate potential outcomes enables him to effectively protect his clients’ rights, particularly with cases involving privacy, surveillance, social media, and drug and alcohol testing.

With clarity and compassion, Denis has achieved exceptional results for his clients including:

  • Ensuring that the duty to accommodate is more than a perfunctory search and that employers consider the circumstances of each individual employee on a case-by-case basis;
  • Protecting a union from employer policies that may interfere significantly with its ability to meet its statutory obligations;
  • Dismissing a bad faith bargaining complaint against a union, holding that the union was under no positive responsibility to disclose a subsidy that it had been providing to a union-administered benefit plan.

Working with trade unions and employees in all areas of labour relations, Denis represents clients in grievance arbitrations, labour board matters, wrongful dismissal cases, and human rights complaints. He has extensive experience appearing before the Canada Industrial Relations Board, the Ontario Labour Relations Board, the Human Rights Tribunal of Ontario, tribunals appointed under the Canadian Human Rights Act, judicial inquests, and at all levels of court in Ontario and Canada.

As managing partner of CaleyWray, Denis leads a highly-qualified legal team in providing a range of services related to labour and employment law, collective bargaining, human rights, and other issues. 

He first joined the firm in 1991 and has been a partner with CaleyWray since 1997.

He lives in Toronto with his spouse Marian and their daughter Georgia.
