About DC Law

DC Law is a small firm based in Markham, Ontario, founded by lawyer Zhuyu (Daniel) Cui. Cui earned a Juris Doctor from the Schulich School of Law at Dalhousie University and worked at other Ontario law firms before starting the practice. The firm's corporate and commercial work centres on private mergers and acquisitions, along with complex corporate transactions and equity investments. Alongside that, DC Law handles real estate transactions, leasing, and financing, wills and estate planning, and immigration matters, and it offers notary public services including notarization, certification, and document authentication.

Cui belongs to the Law Society of Ontario, the Canadian Bar Association, the Ontario Bar Association, the Toronto Lawyers Association, and STEP Canada, the professional body for trust and estate practitioners, which lines up with the firm's estates work. A team of four law clerks and an administrative assistant supports the practice from its office on Steeles Avenue East.

The neighbourhood

DC Law's office is on Steeles Avenue East in Markham, the road that forms the city's boundary with Toronto. Markham has branded itself Canada's Hi-Tech Capital and is home to well over a thousand technology and life-sciences companies, a business backdrop that fits a firm whose main practice is corporate and commercial law.

The city also has one of the country's largest Chinese-Canadian populations, with Statistics Canada recording Chinese as the most reported ethnic background in Markham's 2021 census. A firm handling immigration matters alongside corporate, real estate, and estates work sits naturally in a community with that profile.
