Born in 1926, she came to the central Interior of B.C. as a 19-year-old Radio Wireless Operator for the Department of Transport in the wake of World War II. Her career in community newspapers as an editor and reporter led her to prepare and self-publish a two-volume work. The second volume contains first-person accounts, with introductions. Both pertain to Fort St. James, Fort George and Fort Fraser. The linking up of 'Canada's greatest transcontinental railway', the Grand Trunk Pacific, occurred about two miles east of Fort Fraser on April 7, 1914. Previously a resident of Vanderhoof, L'Heureux lives in Prince George. She was editor of the Ingot for Alcan-Kitimat (1976) and the Smithers Interior News (1975). For 13 years before that she was variously associated with the Nechako Chronicle as editor, publisher and owner before she sold the enterprise.
