About Key Law Professional Corporation

Key Law Professional Corporation is a small firm based in Concord, a neighbourhood in Vaughan, Ontario, with an office on Cidermill Avenue. The practice is built around business law rather than personal litigation, covering asset management and investment funds, corporate and commercial matters, corporate governance, mergers and acquisitions, debt products, and regulatory compliance. It also handles commercial real estate transactions, tax and estate planning for businesses and high net worth clients, and legal work for start-ups in fields such as technology, cannabis, blockchain and fintech.

The firm's two lawyers bring different backgrounds to that mix. Dave Deonarain spent thirty years as a business owner before practicing law, which shapes how the firm approaches commercial files. Monica Gupta is a Barrister and Solicitor with more than a decade of experience in real estate law and civil litigation, fluent in Urdu, Hindi, Punjabi and other South Asian languages, which lets the firm serve clients in their own language on real estate and litigation matters. A law clerk who is also a law student rounds out the team, alongside an office manager who handles the firm's operations.
