Firm Overview:

As a leading independent law firm in Québec, Langlois brings together more than 325 people, including some 185 legal professionals, in our Montréal and Québec City offices. Built on our team’s vast array of knowledge and experience, we deliver proven services tailored to your unique needs: civil and commercial litigation, business, labour and employment, and insurance law. Our approach is always straightforward, honest and highly effective. We understand legal matters can be overwhelming – that’s why we bring a human touch and an attentive ear to your every concern.


Main Areas of Practice:


Employment & Labour Law:

The firm's team of approximately 30 professionals is the largest employment and labour law group in Quebec and is active in all aspects of this area of the law, including employment contracts, collective bargaining, dismissals and disciplinary measures, occupational health and safety, pensions and benefits, and labour disputes.


Commercial Litigation:

Because corporations today are faced with a larger and stricter set of management standards, Langlois Lawyers provides critical guidance for its clients. Dealing with such issues as shareholder disputes, directors’ liability and corporate governance, the firm has mastered the art of managing large-scale complex litigation files.


Business Law:

The firm covers all legal aspects of the activities of small, medium and large businesses in the private, public and parapublic sectors, including the organisation, dissolution and liquidation of corporations, mergers and acquisitions, banking and finance, public offerings of securities, and international business transactions. The firm has particular expertise in financial restructuring and insolvency related matters.


Insurance Law:

The firm's insurance law team is highly regarded in litigation matters involving insurance products and their distribution and registration. Higher solvency requirements in this industry and a more demanding regulatory framework make our strategic legal advice highly sought after. The firm leverages their industry knowledge to uphold their clients’ interests effectively.


Class Actions:

Because class actions are often national or international in scope, the firm takes preemptive action to minimise risk. With extensive experience in complex litigation, the firm's professionals are on the cutting edge of developments in this area. The firm represents clients in class proceedings involving insurance, financial products, pharmaceuticals, manufacturers and pension plans.


Construction Law:

The firm's construction experts act for plaintiffs and defendants in matters such as design and construction defects, additional work, claims, surety bonds, calls for tenders, BSDQ (depository for bids) and statutory liens. At any given stage of a project, the firm's lawyers are able to offer outstanding guidance to professionals in the construction sector.


Securities Litigation:

The firm's litigation team represents clients in all matters involving the investment sector. The firm frequently appears before the Quebec Securities Commission (AMF), the Investment Industry Regulatory Organization of Canada (IIROC), the Canadian Association of Mutual Fund Dealers and all levels of the courts, including the Quebec Court of Appeal, the Federal Court of Appeal and the Supreme Court of Canada.


Technology Litigation:

The lawyers and trademark agents in the firm's technology law group are specialists in the areas of IT governance and regulatory compliance. The firm's group advises its clientele on e-commerce and the development and implementation of computer systems and applications pursuant to licences or service contracts.


Maritime Law:

The firm has 80 years of experience in this field, including ship acquisition, operation and financing, hull and P&I insurance, collision, salvage, general average, and virtually all other aspects of admiralty law. The firm has also been involved in marine environmental issues and in the energy sector, including the supply and marine transportation of oil and gas.
