Canada Business Corporations Regulations, 2001

18 A corporate name is confusing with

• (a) a trademark or an official mark if it is the same as that trademark or official mark or if the use of both the corporate name and either the trademark or the official mark, as the case may be, is likely to lead to the inference that the business carried on or intended to be carried on under the corporate name and the business connected with the trademark or official mark, as the case may be, are one business, whether or not the nature of the business of each is generally the same; or

• (b) a trade-name if it is the same as that trade-name or if the use of both names is likely to lead to the inference that the business carried on or intended to be carried on under the corporate name and the business carried on under the trade-name are one business, whether or not the nature of the business of each is generally the same.
