About Preston Legal

Preston Legal is a small employment and labour law firm in London, Ontario, that represents employers and business owners rather than individual employees. Nic Preston founded the firm in 2023 and works alongside one associate lawyer from an office in Tower B at 380 Wellington Street, in the city's downtown core. Preston is dual qualified in Ontario and South Africa, having held a partnership at a large South African law firm before continuing a legal career in Canada in 2019.

The practice covers the employer side of the workplace relationship: employment contracts, terminations and restructuring, workplace investigations, labour arbitration, and human rights complaints before the Human Rights Tribunal of Ontario, along with compliance under the Employment Standards Act and the Occupational Health and Safety Act. It has also added bid and tender advice and technology and procurement agreements to its services. Beyond the practice, Preston teaches Law for Human Resources at Western Continuing Studies, a course required for Western University's Post-Degree Diploma in Human Resources.
