CGC Inc. has announced that it has begun construction of its new manufacturing plant in Wheatland County, Alta., east of Calgary. The 220,000-square-foot facility represents a $210 million investment. It will manufacture CGC’s Sheetrock brand of wallboard and create more than 100 permanent, full-time jobs, the company says. “This project underscores our commitment to being the best wallboard manufacturer to do business with, particularly as builders, governments and communities across Alberta and the West work to expand housing starts, accessibility and affordability,” said Chris Griffin, CEO of USG Corporation, CGC’s parent.
