AFCI breakers have been required for circuits feeding electrical outlets in residential bedrooms by the electrical codes of Canada and the United States since the beginning of the 21st century; the U.S. National Electrical Code has required them to protect most residential outlets since 2014, and the Canadian Electrical Code has since 2015. In parts of the world using 230 V, where the higher voltage implies lower currents, specifically Western Europe and the UK, adoption is slower, and their use is optional, except in high risk cases.

Where Canadian English shares vocabulary with other English dialects, it tends to share most with American English, but also has many non-American terms distinctively shared instead with Britain. British and American terms also can coexist in Canadian English to various extents, sometimes with new nuances in meaning; a classic example is holiday (British) often used interchangeably with vacation (American), though, in Canadian speech, the latter can more narrowly mean a trip elsewhere and the former can mean general time off work. Canadian English morpho-syntactic features also affect their vocabulary; this includes their tendency to use the possessive ''have'' as opposed to ''have got'' or ''got,'' which differs from both British English and American English. In addition, the vocabulary of Canadian English also features some words that are seldom (if ever) found elsewhere. A good resource for these and other words is the Dictionary of Canadianisms on Historical Principles, which is currently being revised at the University of British Columbia in Vancouver, British Columbia. The Canadian public appears to take interest in unique ''Canadianisms'': words that are distinctively characteristic of Canadian English--though perhaps not exclusive to Canada; there is some disagreement about the extent to which ''Canadianism'' means a term actually unique to Canada, with such an understanding possibly overstated by the popular media. As a member of the Commonwealth of Nations, Canada shares many items of institutional terminology and professional designations with the countries of the former British Empire -- for example, constable, for a police officer of the lowest rank, and chartered accountant.
