HALIFAX - A historic Canadian undergarment factory famed for long johns and boxer shorts is about to rapidly reinvent itself as a domestic producer of medical gowns.

Stanfield's Ltd. of Truro, N.S., is among five firms that Prime Minister Justin Trudeau announced Tuesday have received letters of intent to manufacture personal protective equipment and clothing for front-line health workers.

Jon Stanfield, the chief executive of the fifth-generation family firm, said in an interview he's already sourced approved fabric from nearby Intertape Polymer, and is ready to be producing medical clothing within days.

The 48-year-old says once the federal government provides details of its offer, the company could bring back over 75 of its over 200 staff who were sent home earlier this month as a result of the COVID-19 pandemic.

He describes the restart as a "pivotal" signal that Western governments are moving to ensure there are domestic suppliers of medical gear and gowns crucial to public safety in the future.

Stanfield said the firm has patterns and machinery that would initially produce more than 2,000 gowns daily per shift to help feed a Canadian demand for garments that emerged after the pandemic sliced supply from China.
