Harinder S Gahir

Lawyer, Mediator & Arbitrator

Harinder Singh Gahir has been practicing law in Ontario since the year 2000. He is a former Vice-Chair of the Licence Appeal Tribunal (Ontario) and a former Chair of the Canada Pension/Old Age Security Review Tribunal.

His mediation background has taught him to resolve conflicts collaboratively, and where mediation is not an option, his adjudication and arbitration background has led him to make fair decisions for the stakeholders.

Harinder holds a Bachelor of Arts and Bachelor of Laws degrees and is a member of the Law Society of Upper Canada. In 2019, he completed his LL.M. from Osgoode Hall Law School. 

Harinder has successfully represented his clients before several tribunals including the Immigration & Refugee Board, Human Rights Tribunal, Local Planning Appeal Tribunal (LPAT) and the Federal Court. His practice areas include Corporate & Commercial law, Commercial and Development Real Estate, Administrative Law, and complicated immigration cases.

Among his many community and professional activities, he has served as a Board member of Peel Law Association, President of Peel Multicultural Council and an Executive Member of the Canadian Bar Association, Immigration Section, Southern Alberta.

After getting call to the Bar, Harinder realized his law credentials could come in handy in serving his community. Since then, he has helped many by providing quality services and extending a helping hand to those in need. For Harinder, the meaning of success is the number of people he has been able to help during his career.

Harinder has been interviewed by many media outlets, including The Toronto Star, Calgary Herald, and Omni Television. Most interviews focused on his expert comments regarding immigration law changes in Canada and matters related to the South Asian community.

In his free time, Harinder likes to spend quality time with his family. In addition, he is an avid traveler and loves to explore new terrains.
