About Kirwin Partners LLP

Kirwin Partners LLP is a law firm in downtown Windsor, Ontario, on Pelissier Street. The firm has practised there since 1991, and its current lawyers bring a combined 265 years of legal experience to corporate and commercial law, real estate, civil litigation, family law, personal injury law, and wills and estates. Within those groups, individual lawyers also take on employment disputes, construction claims, insurance litigation, and insolvency matters.

Windsor's location across the river from Detroit shows up in some of the firm's corporate and immigration work. One lawyer has acted as Canadian counsel for U.S.-based multinational corporations, and another combines corporate law with immigration and cross-border matters. Two of the firm's lawyers have also served as sessional instructors at the University of Windsor's Faculty of Law, teaching contracts, business associations, and civil trial advocacy. One family law partner at the firm is a Law Society of Ontario Certified Specialist in Family Law.
