About USA CA Lawyer

USA CA Lawyer is a Toronto general practice founded by Sunny Wu, who is dual licensed to practice law in Ontario and the United States. Wu earned a B.A. from the University of Toronto and a J.D. from Barry University School of Law in Florida, and is admitted to practice in New York, New Jersey, and the U.S. District Court for the Southern District of New York, in addition to being a Barrister, Solicitor, and Notary Public in Ontario. Wu is also a partner at a separate New York based law firm, where cross-border wills, estate planning, and U.S. immigration matters are handled alongside the Toronto practice. The firm is fluent in Mandarin and Cantonese as well as English.

From its Toronto office, the firm covers civil litigation, wills and estate planning, criminal defence, real estate transactions, family law, and Landlord and Tenant Board matters, working with a team of lawyers and licensed paralegals. The team also includes speakers of Tamil, Hindi, and French. One senior legal advisor at the firm was called to the bar in Ontario, England, and India, has served as a Deputy Judge, and has practiced law for over 40 years, alongside a lawyer who is a Barrister and Solicitor in Ontario and an Attorney at Law in Sri Lanka. The firm offers both hourly and flat rate fee structures and a free consultation, and continues to serve clients by phone and virtual meeting.

The neighbourhood

The firm's Toronto office sits in Splendid China Mall at Steeles Avenue East and Redlea Avenue, a Chinese themed shopping and office centre in northeast Scarborough that opened in 2007. The mall sits right on the border with York Region, across from Pacific Mall and next to Milliken GO Station, which fits a firm that describes its own practice as serving Toronto and the York Region and that offers services in Mandarin and Cantonese.

It's a setting built around a specific community rather than a downtown legal district, and the firm's own pages point clients toward Toronto and Markham for its family law and estate work, which lines up with that Steeles Avenue corridor location.
