New Brunswick’s natural resources minister says he’s working closely with Irving Paper to ensure a durable solution is in place to save jobs at its Saint John mill. John Herron said the need to protect the plant on Bayside Drive on Saint John’s east side was urgent, given the number of high-paying jobs – 143 – and economic activity at stake. …“It’s certainly not lost on me that the plant is very important to the regional economy and the provincial economy. …J.D. Irving, Limited, the mill’s parent company, announced early last week that it would shut down one of its two machines at the old plant because it said NB Power’s high industrial rate for electricity was making it uncompetitive in the global paper industry. …The machine that’s being shut down is the most energy intensive of the two.
