Interlocutory injunction granted in favour of the Tsilhqot’in Nation against Taseko Mines Limited work permit, on the basis that it infringes their Aboriginal rights.
Taseko Mines Limited [“Taseko”] applied to prohibit members of the Tsilhqot’in Nation [“Tsilhqot’in”] from blockading its access to an area where the mining company wants to carry out an exploratory drilling program [“NOW program”]. Taseko has access pursuant to a notice of work permit [“NOW permit”] issued under the Mines Act. That application is now moot since the Court decided Tsilhqot’in’s application will succeed for an injunction prohibiting Taseko from carrying out its NOW program until the Tsilqot’in’s underlying claim to quash the NOW permit is heard.
In this matter, the issue is whether granting Tsilqot’in the interim injunction prohibiting Taseko from undertaking the NOW program would amount to a final determination of the action, which would effectively remove any benefit of proceeding to trial. The NOW permit will expire in July 2020, and if Taseko is enjoined until the action is heard, it is very unlikely the trial could be completed in time to for the 4-6 weeks required to complete the NOW program. In the Court’s view, the extension is essentially mechanical and concludes that Taseko will have until July 2022 to complete the NOW program, because Taseko can extend the NOW permit by two years under s 5(1) of the Permit Regulation.
Issues pertaining to infringement and justification, which will be the focus of the trial, are not new to the parties. Because some of the factual and legal elements have been argued before different courts for years, the discovery process will not be as time consuming as it would be if the issues were new to the parties. Based on the evidence and submissions before the Court, if the parties prioritize the matter, the timeline should be adequate to prepare for trial. The injunction is not tantamount to granting relief nor is it bound to impose a hardship removing any benefit of trial. The threshold merits test is the serious question to be tried standard (R v Canadian Broadcasting Corp, 2018 SCC 5). This threshold is relatively low as a prolonged examination of the merits is generally neither necessary nor desirable (RJR-MacDonald Inc v Canada,  1 SCR 311).
It was determined that given the nature of the harm to the Tsilhqot’in, and the waiving of the undertaking as to damages, there was a material risk of irreparable harm to both parties. When there is a risk of both parties suffering a material risk of irreparable harm, the court should favor the status quo (AG British Columbia v Wale (1986), 9 BCLR (2d) 333 (CA)). It was determined that the NOW program would change the status quo as it would disturb the land. The Tsilhqot’in stand to suffer greater irreparable harm if the injunction is not granted. Despite that the Tsilhqot’in pursued a self-help remedy of a blockade outside the courts, the imperative of reconciliation was such that the balance of convenience was in the Tsilhqot’in’s favour.
