Corporate & Securities Law Experts in Calgary
At Heighington Law Firm, we exist to serve our clients by delivering the same results one would expect from a large law firm but at prices and with a level of customer service that only a small firm can offer. With nearly 25 years of experience in corporate and securities law, we focus exclusively on these practice areas, allowing us to provide superior expertise while remaining agile and adaptable. Our approach centers on listening carefully to client needs, communicating clearly, and diligently pursuing practical solutions that represent real value. We have built a reputation as a 'fixer' of failed transactions caused by inexperienced advisors, particularly in capital markets and regulatory matters.

Our clients include private and publicly listed companies across Canada, with a strong presence in mining, technology, oil and gas, and industrial sectors. We pride ourselves on maintaining strong client relationships through prompt communication, transparency, and a commitment to understanding each client's unique challenges and goals. Our team combines deep legal knowledge with practical business advice, having advised issuers and public companies on corporate governance, continuous disclosure, mergers and acquisitions, and stock exchange listings. We maintain connections with senior professionals in related fields to provide comprehensive solutions and trustworthy referrals when needed.
