Lorenzo is Leader of the firm's Workplace Law Group. He has practised exclusively in the area of labour and employment law for over 30 years, representing employers on all areas touching labour and employment law, both provincially and federally. 

Lorenzo has developed a practical, business-oriented approach and has built a long list of loyal clients who depend on him for direct solutions, risk analysis and strategic advice. Cognizant of the time pressures and deadlines most employers experience in today’s workplace, he combines focused, calm and proactive advice with exceptional client service, while remaining approachable to all levels of the organization.

His expertise spans the broad spectrum of workplace law, whether it be defending employers against employee claims (wrongful and constructive dismissal, human rights, harassment) or dealing with a unionized workplace. He has extensive experience in grievance and labour board litigation, injunctive proceedings, responding to union organizing and applications for certification, collective bargaining and grievance arbitration. Lorenzo also advises his management clients on acquisitions, divestitures and restructurings, enforceability of restrictive covenants and the application of various labour and employment statutes. 

Lorenzo writes and speaks extensively. He is the originator of the Aird & Berlis Workplace Law webinar series which provides one hour webinars on current and topical labour and employment issues, and which offers practical advice and tips for employers in navigating the complex laws and rules of the workplace. He also has developed and presents management training seminars on a wide variety of topics, including human rights, union organizing defence strategies, strikes and lock outs, employment policies and procedures and risk management.
