Virtual appointmentsAbout Mayo Law
Mayo Law is a small cross-border law firm with offices in Toronto and New York, serving individuals, families, founders, investors, and businesses whose legal needs cross the Canada-US border. The firm describes its own positioning as Toronto-first, with cross-border work added when a client's business or family situation calls for it. Its practice covers Canadian and US immigration, Ontario real estate, business and corporate law, compliance and risk management, white collar defense, and notary public services in both Ontario and New York.
The firm operates through two affiliated entities, Mayo Law PC in Ontario and Joseph Mayo PLLC in New York, each licensed and responsible for its own jurisdiction. Joseph Mayo, the firm's principal attorney, holds a Master of Laws (LL.M.) from New York University School of Law, is licensed with the Law Society of Ontario and the New York State Bar, and belongs to the American Bar Association. That dual licensure means a client with matters spanning both countries can work with a single firm rather than retaining separate counsel in each one.

The neighbourhood
Mayo Law's Toronto office is in First Canadian Place at 100 King Street West, Suite 5600, at the corner of King and Bay in the Financial District. First Canadian Place has been one of Canada's tallest office towers since it opened in 1975, holding the national height record until 2025, and it now serves as the global operational executive office of the Bank of Montreal. It's a fitting address for a practice built around business, corporate, and cross-border transactional work rather than neighbourhood walk-in matters.
The New York office sits on the 23rd floor at 165 Broadway, also in a Financial District, this one in Lower Manhattan. The building, known as One Liberty Plaza, opened in the early 1970s on the site of the former City Investing Building, with Zuccotti Park directly to its south. A Bay Street tower and a Broadway high-rise put Mayo Law inside the commercial cores that its founder and investor clients are usually building businesses in or moving into.
Frequently asked questions
- Can Mayo Law help me buy or sell a home somewhere in the GTA besides Toronto proper?
- Yes. Mayo Law handles residential and commercial real estate matters across Toronto and the wider Greater Toronto Area, not just within the city itself. Contact the firm directly to confirm coverage for a specific municipality.
- What does a real estate closing with Mayo Law typically cost?
- Costs vary by transaction, since a purchase, sale, refinance, or commercial deal each involve different legal work. Contact Mayo Law directly for pricing specific to a particular transaction.
- My company needs to hire or transfer an employee across the Canada-US border. Can Mayo Law help?
- Yes, this is one of the firm's core areas. Mayo Law advises employers on business immigration categories including E-2 treaty investor status, L-1 intracompany transfers, and TN and H-1B routes, along with related employer compliance work such as LCA filings and cross-border hiring strategy.
- Why does Mayo Law operate as two separate legal entities instead of one firm?
- Ontario and New York each require a lawyer to be licensed and to practice through an entity organized under that jurisdiction's own rules. Mayo Law PC provides the Ontario services and Joseph Mayo PLLC provides the New York services, and each entity is responsible for its own jurisdiction. Sharing the Mayo Law name and the same principal attorney is what lets a client with matters in both countries work with one firm instead of two.
- Can Mayo Law notarize documents that need to be used in both Canada and the US?
- Yes. The firm offers notary public services in both New York and Ontario, including in-person and remote notarization where permitted, certified copies and affidavits, cross-border document notarization, and coordination of apostilles.
