Customs detains goods at the border when directed by the courts to do so only under the Trade-marks Act and the Copyright Act. There is provision for detention of imports of infringing goods under the Integrated Circuit Topography Act (section 14), but, to date, this has not been used for any action to be taken by Customs Officials.
Section 57 of the Patent Act, together with the inherent equitable authority of the superior courts, would allow such courts to order, where appropriate, that infringing goods not be imported into Canada.
