About Weilers LLP
Weilers LLP is a full-service business and law firm based in Thunder Bay, operating under the formal name Weiler Maloney Nelson LLP. Its roots go back to G.B. "Bernie" Weiler, who started the practice at a mining camp in Hardrock, Ontario, and who the firm credits as a pioneer in bringing labour law expertise to Northwestern Ontario. More than 79 years later, the firm still works from Thunder Bay and still serves the region that shaped it.
Today a dozen lawyers cover corporate and commercial law, real estate, wills and estates, family law, labour and employment, civil litigation, and a mining and Aboriginal law group that grew out of that original mining camp practice. The mining team advises exploration, development, and operating companies as well as engineers and contractors working in the resource sector, while the Aboriginal law practice works with First Nations communities and individuals across the firm's other practice areas, including band management and treaty rights matters. Corporate work runs from incorporations and shareholder agreements through mergers and franchising.
Outside client work, the firm's lawyers stay active in Thunder Bay community life, including local charity fundraisers and a long standing relationship with the Thunder Bay Chamber of Commerce.
