In 2004, Frigault created the web portal stopbennett.com to help concerned residents of Northern New Brunswick stop the company from operating its incenerator in Belledune, located in the Baie des Chaleurs region of the province. The portal garnered over 10,000 signatures for a petition that was delivered to Bernard Lord, former Premier of New Brunswick. After spending most of his career as a marketer of both enterprise software and travel products in Toronto, Montreal and Boston, Frigault returned to Bathurst in 2007 to serve as President of NU Exchange, Incorporated., a marketing company that he founded, and to pursue his dream of establishing an edible forest garden based on the pioneering work of Robert Hart in the United Kingdom. The edible forest is located at Stonefly Acres, a 100-acre (040 km2) private property outside of the city of Bathurst.
In March 2009, Frigault co-founded nthWORD, an online arts & culture magazine.
