Electrical certification in Canada
LED walls are electrical equipment. In Canada they need a recognized certification mark before they go on the wall.
An LED display is a powered electrical assembly. Certification means an accredited lab has tested the product against safety standards so inspectors and insurers have something to point at. Skipping that step is how projects stall at inspection.
In Canada, look for marks from bodies such as CSA, UL, Intertek (ETL), or TÜV Rheinland, among others that are accepted under the Canadian system. The Canadian Electrical Code and provincial rules decide what is legal to connect. The integrator and the electrical contractor should confirm the mark on the exact model being installed, not a cousin in the brochure.
Certification covers electrical safety. It is not a substitute for structural engineering on a hanging wall, or for IP ratings on an outdoor sign.
