Questions & Answers

What does Mayo Law do?

Mayo Law is a cross-border law firm with offices in Toronto and New York. We handle business and family immigration (including the E-2 treaty investor visa, L-1, H-1B, TN, EB-1, EB-2, EB-3, EB-5, and PERM), residential and commercial real estate across the GTA, business and corporate law, international business, white collar defense, regulatory compliance, and notary public services in both Ontario and New York.

 

Mayo Law has two offices.

The Toronto office is at 100 King Street West, Suite 5600, Toronto, ON M5X 1C9, reachable at +1 (416) 708-6010.

The New York office is at 165 Broadway, Floor 23, New York, NY 10006, reachable at +1 (646) 662-2782.

We serve clients across Ontario, the GTA, New York State, and globally for cross-border matters.

Yes. Mayo Law provides legal services through two affiliated entities. In Ontario, services are provided by Mayo Law PC under the Law Society of Ontario. In New York, services are offered by Joseph Mayo PLLC under the New York State Bar. Each entity operates independently and is responsible for its own legal services, while sharing the same team and firm standards across the border.

Joseph Mayo is the principal attorney at Mayo Law.

He is licensed to practice law in both Ontario and New York, holds a law degree from New York University School of Law, and is a member of the American Bar Association and the Law Society of Ontario.

His practice focuses on cross-border immigration, real estate, business law, white collar defense, and compliance.

Yes. Cross-border work is the core of our practice. We handle US work visas and investor visas for Canadians and treaty-country nationals, US tax and immigration planning for Canadian real estate buyers, cross-border M&A and contracts, multi-jurisdictional compliance programs, and notary work that must be recognized in both countries.

Because we are licensed and located in both Ontario and New York, coordination happens inside one firm rather than across multiple firms.

The fastest path is to call our Toronto office at +1 (416) 708-6010 or our New York office at +1 (646) 662-2782, email info@mayo.law, or visit mayo.law/contact to schedule a consultation.

Most matters start with a brief intake call to understand your situation, followed by a paid consultation if the matter is one we can take on.

No. Use of this website and initial contact with our firm does not create an attorney-client relationship.

An attorney-client relationship is only formed once a written engagement agreement is signed by both parties.

Please do not send confidential information through the website or by email until that relationship has been formally established.

Both.

Mayo Law works with individual clients on real estate transactions, immigration matters (E-2 investor visas, family-based petitions, Canadian citizenship and Bill C-3 matters), notary services, and personal compliance or defense matters, as well as with businesses on incorporation, contracts, M&A, employment-based immigration, white-collar defense, and compliance programs.

The firm advises both sides — a founder structuring a startup or a multinational entering Canada, and a family closing on a home or filing an immigration application.
