Police, Ontario’s law regulator and Grewal’s father-in-law allege more than $200M in fraud
Rajvinder “Raj” Grewal, the former Liberal member of Parliament for Brampton East, Ontario, is under simultaneous legal siege from Peel Regional Police, the Law Society of Ontario (LSO), and his own father-in-law — all over alleged misconduct at RSG Law, the Mississauga firm he founded.
Civil disputes against Grewal and associates exceed $200 million, according to recently filed lawsuits. None of the allegations has been established in court.
From Parliament to police probe
Grewal represented Brampton East from 2015 to 2019, resigning from the Liberal caucus that year after admitting to gambling debts of several million dollars. He founded RSG Law shortly after, a firm a 2025 paid advertorial in the Toronto Star called a “thriving legal enterprise.”
Earlier this year, Grewal voluntarily surrendered his law licence as the LSO launched a formal investigation into alleged mortgage and trust fund misconduct, coming amid Ontario’s escalating enforcement actions against mortgage fraud in 2025 and 2026.
In September, the regulator escalated further, filing to seize all RSG Law accounts, client files, and safe-deposit boxes. Only $340,303 remains in the firm’s accounts, according to the LSO’s notice of application.
Peel Regional Police confirmed on October 9, a criminal investigation into “multiple” allegations of fraud and breach of trust at RSG Law, part of Ontario’s mounting mortgage fraud and trust account enforcement actions.
Grewal’s lawyer Simon Bieber maintains his client denies wrongdoing, is co-operating with the LSO, and “looks forward to continuing his defence,” adding that Grewal is “working diligently to resolve all outstanding litigation in a manner that is fair to all involved.”
Receivership and a father-in-law’s allegations
The legal crisis has also engulfed Grewal’s real estate arm. RSG Mayfield Inc., of which he is sole director and officer, was placed into receivership after defaulting on a $26,269,753.66 loan secured against an undeveloped Mayfield Road residential site, according to Insolvency Insider Canada.
Financed in 2025 by Vector Financial Services Limited and Olympia Trust Company, a court has since appointed TDB Restructuring to manage the sale.
The affair has also divided Grewal’s family. Father-in-law Kailash Kasal, a Brampton businessman, swore an affidavit on September 25, alleging Grewal used his companies and properties to fraudulently secure tens of millions in mortgage loans without his knowledge.
Kasal states the electronic signatures on mortgage documents purporting to be his were not his, and that an ink signature attributed to his wife was “a clear forgery.”
He has since cross-sued Grewal, Davinder Singh Khattra — RSG Law’s listed new owner, whose licence has also been suspended — and RSG Law itself, seeking $1 million in damages for “negligent and/or fraudulent misrepresentation.”
The LSO’s application references lawsuits alleging at least $17 million misappropriated from RSG Law client accounts, while National Bank of Canada is separately seeking $4.1 million in allegedly diverted mortgage funds.
In a June ruling in that case, Ontario Superior Court Justice Frederick Myers found the “funds are unaccounted for and appear to have been misappropriated by the defendants.”
