Incorporated in 1995, Zerem Electrical Services Ltd. is a full-service electrical contractor serving clients throughout the Greater Toronto Area. Our work spans some of the GTA’s largest high-rise residential projects, electrical works for new public transit infrastructure, fire alarm system retrofits, and emergency generator replacements.

Our experienced management team and large pool of qualified electricians handle the full range of electrical work: power distribution, lighting, fire alarm, emergency generators, and EV charging. Where a project calls for it, we also act as prime contractor, managing and coordinating subcontracted mechanical and civil works and associated design services.

Our Commitment to Quality, Safety and the Environment

Zerem’s integrated management system is independently certified to three international standards:

• ISO 9001:2015: Quality Management System
• ISO 14001:2015: Environmental Management System
• ISO 45001:2018: Occupational Health and Safety Management System

These certifications cover the construction, installation, commissioning and maintenance of electrical works, and prime contractor services, across residential, commercial, industrial, institutional and infrastructure projects. Our systems are audited by an accredited third-party registrar on an annual surveillance cycle, so the processes our clients rely on are reviewed and improved continuously.

We provide quality service and professional solutions built around our customers’ requirements, delivered safely and responsibly.
