About WeirFoulds LLP

WeirFoulds LLP is a Toronto-based law firm that traces its history back to 1860, when Theodore H. Spencer began practising law in the city. By 1870 the firm was known as Spencer and MacDonald, and it took its current name, Weir & Foulds, in 1970. Today it operates from the TD Bank Tower at 66 Wellington Street West in downtown Toronto, with a second office in Oakville, and it focuses on four broad areas: litigation, corporate, property, and government law. Within those areas its lawyers cover ground from construction and real estate to Indigenous law, tax, health law, and technology and startups.

Fourteen lawyers who worked at the firm have gone on to federal judicial appointments, the first in 1883 and the most recent in 2021, and eight of them reached a court of appeal, including the Supreme Court of Canada. WeirFoulds belongs to SCG Legal, an international network of 125 law firms across 65 countries, and it has held SOC 2 data security certification every year since 2023.

In the community

  • WeirFoulds has long supported Pro Bono Ontario and was the first recipient of that organization's McMurtry Award.
  • During the early months of the COVID-19 pandemic, several of the firm's associates volunteered on Pro Bono Ontario's phone hotline as calls about employment and housing problems climbed sharply.
  • A firm partner provided pro bono legal support in a case that led Antigua and Barbuda's High Court of Justice to strike down the country's criminalization of consensual same-sex intimacy as unconstitutional in July 2022.
  • For Asian Heritage Month in 2026, the firm partnered with Partial Gallery and OCAD University on an art selection initiative to acquire and unveil an original artwork by a recent OCAD University graduate of Asian heritage, alongside a meal showcasing Asian cuisines.
