A JDI spokesperson says jobs could be at risk if a proposed rate hike for natural gas gets the green light.
Mary Keith says the application by Enbridge Gas, for what they are calling a "slight increase" in bills for commercial and industrial users, is concerning.
She tells CHSJ News they're the main source of natural gas for their Atlantic Wallboard plant in Saint John.
"I think in all of our operations we're looking to ensure that we have got competitive fuel sources, and we've worked very hard to reduce our footprint in terms of greenhouse gases, through options like natural gas, or biomass."
Enbridge wants to see the new distribution rates take effect on the first day of the new year.
