MARTINSBURG, W.Va. — Procter & Gamble is already adding products to its large manufacturing plant being built in Martinsburg. Some of that business will come from a plant the company is closing in Ontario, Canada.

P&G told 500 workers at its Brockville, Ont., plant Wednesday that it will permanently close the plant by late 2020 or early 2021 and move production to West Virginia, according to a report on CBC Radio Canada.

The Brockville plant has been in operation for nearly 40 years. The company told the workers it’s been studying its North America supply chain for several years.

The CBC report quoted Procter & Gamble spokesperson Jeff LeRoy.

“News like this is never easy. We wanted our employees who are our top priorities to go home and spend this time with their families, their friends, their loved ones, and talk about it. Talk about what they wanted to do with their future.”

The Brockville plant produces Swiffer dusters, fabric softeners and Tide-to-go detergent pens. It appears at least the Swiffer brand will be produced at the Tabler Station plant under construction in Martinsburg.

U.S. Senator Joe Manchin welcomed the news in a Thursday statement.

“Today’s announcement further underscores the long-term commitment this world-class company has made in our state and our workforce. Manufacturing jobs will carry our economy forward, and help keep more West Virginians in West Virginia – raising children, supporting families, and making lasting contributions to our communities,” Manchin said.

P&G has already announced it will produce Pantene, Head & Shoulders, Olay, Old Spice and Bounce at the Martinsburg facility.

The Martinsburg plant is expected to have about 700 workers. The addition of Swiffer products does not change those projections, Leroy told MetroNews Thursday.
