About Gurpreet Mangat Law Professional Corporation

GM Law Firm, the business name of Gurpreet Mangat Law Professional Corporation, is a Brampton, Ontario law practice founded in 2016 by lawyer Gurpreet Mangat. Mangat earned a Bachelor of Laws from Punjab University in Chandigarh in 2002 and was called to the Ontario bar in 2016 after completing licensing training in Toronto. The firm works from a single office on Main Street North in Brampton and serves clients across Peel Region, rather than running multiple branch locations.

The practice covers real estate, immigration, business law, and wills and estates. On the real estate side, GM Law handles residential and commercial purchases, sales, leasing, mortgage refinancing, and title transfers. Its immigration work spans spousal and family sponsorship, super visas, work and visitor permits, express entry, citizenship applications, immigration appeals, judicial review, and procedural fairness matters. The firm also drafts shareholder agreements and business contracts, prepares wills, and advises executors and administrators settling estates under Ontario law. Mangat is additionally commissioned as a notary public, so the firm handles document notarization and certified copies alongside its legal work.

The neighbourhood

GM Law's office sits on Main Street North in Brampton, a city that has grown into one of the largest in the country. Brampton's population reached 791,486 in 2024 and the city counts residents from 250 cultures speaking 171 languages, according to its own figures. That kind of growth means a steady stream of newcomers buying their first home, sponsoring family members, or starting a small business, which lines up closely with the mix of real estate, immigration, and business work GM Law handles day to day from its Brampton office.
