What is the test for a statutory injunction?

The petitioner relies on Madam Justice Gropper's decision in British Columbia v. Shawn Roofing, 2016 BCSC 2465, as authority for the proposition that the court must grant an injunction if there are reasonable grounds to believe that the respondents have contravened and are likely to continue to contravene the statute or the regulation. The petitioner says the public interest is engaged in ensuring compliance with the statute and that the discretion as to whether to decline to grant a statutory injunction is much narrower than is the case for an equitable injunction.
