About ULC and how we can help you

ULC … Working for a safer world

Underwriters Laboratories of Canada (ULC) is an independent product safety testing, certification and inspection organization. We have tested products for public safety for 90 years and we are accredited by the Standards Council of Canada and International Accreditation Service, Inc.

Founded in 1920, ULC is a key architect of the Canadian National Safety System, administered by the Standards Council of Canada (SCC). ULC’s time-tested system supports governmental product safety regulations, and it complements federal, provincial, and municipal public safety initiatives. ULC also works with other governments and international safety systems to help further international trade with adherence to local and international safety requirements.

Standards for safety

ULC Standards is an independent, not-for-profit standards development organization. ULC Standards has developed safety and performance standards and specifications for 90 years and is accredited by the Standards Council of Canada, under the National Standards System.

ULC Standards publishes and maintains close to 300 Canadian safety standards and other related documents. These standards play an important part in improving public safety. ULC Standards employs a consensus-based process of developing effective product safety standards, using input from consumers, manufacturers, government agencies, users, regulatory authorities and other interested parties.

Making products safer for people

ULC evaluates a broad range of products, components, materials and systems for compliance to specific requirements. Today, ULC helps companies bring safer products to Canadian and global marketplaces.

ULC’s safety certification services include testing, evaluation and factory surveillance of products to Canadian and international standards for safety. These certifications enhance the safety of products as well as the public’s confidence in their compliance.
