Temporary Foreign Worker legal challenge[edit]

In 2013, IUOE Local 115, along with the BC Building Trades Union, had tried to overturn permits given to a Murray River coal mine near Tumbler Ridge, British Columbia to hire 201 Chinese temporary workers to work on a new mine owned by Chinese nationals. The unions claimed that the job ads were written to exclude Canadian workers, and instead chose to hire Chinese workers for lower wages rather than source or train local miners from the immediate area or the province.

However, a federal court judge disagreed. Russell Zinn found that HD Mining, the owner of the coal mine, had fulfilled the requirements set out in a federally mandated Labour Market Opinion (LMO) and dismissed the unions’ challenge. However, public and media attention on the case resulted in some changes being implemented into the Canadian Temporary Foreign Worker Program to ensure that foreign workers are not chosen over local resources, where available.
