In Ontario, most electrical work legally requires a licensed electrical contractor, not just someone handy with tools. A licensed electrician has completed a recognized apprenticeship and certification (such as the 309A Construction and Maintenance Electrician license), and the contracting business itself holds an ESA license.
A handyman replacing a light switch cover or a lamp isn't usually an issue. But panel work, new circuits, rewiring, or anything that could affect life safety should go through a licensed electrician, both because it's the law and because it's what keeps your home insurable if something ever goes wrong.
