The registrar either finds the mark eligible or ineligible for registration. An owner may appeal the registrar's ineligibility decision to the court. For an eligible mark the next step is for CIPO to issue a notice of the application's approval for advertisement. The application and trademark must then be advertised in the "Trademarks Journal" for two months, providing a window of opportunity for opponents to file a statement of opposition to the proposed registration. Section 38 of the Act requires opponents to provide detailed specifications of the grounds for opposition, such that the applicant has a fair opportunity to rebut the allegations and meet their onus of satisfying the registrar that registration is warranted.
