About Diversitas Law Group

Clients rate this firm highly on Google.

Diversitas Law Group is an association of independent sole practitioners who share office space and administrative resources at 100-145 Wharncliffe Road South in London, Ontario. It isn't a law firm, partnership, or limited liability company, and each practitioner runs a separate practice, so a client's solicitor-client relationship is with that individual practitioner rather than the group as a whole. The group's practitioners were formerly associated with an immigration law office in Southwestern Ontario founded by the late Edward Charles Corrigan, whom the Law Society of Upper Canada certified as a specialist in citizenship and immigration law and in immigration and refugee protection law in 2004, and they've carried that focus forward under the Diversitas name.

Between them, Diversitas practitioners handle immigration, citizenship, and refugee protection matters, plus family law and residential real estate. Two are lawyers called to the Ontario bar, Harkamal Singh in June 2016 and Li Tian in 2019, alongside a Law Society licensed paralegal and a Regulated Canadian Immigration Consultant. The group has over 30 years of combined experience in immigration, citizenship, and refugee protection law and has helped hundreds of people with those matters, and it can serve clients in Arabic, Spanish, Mandarin, Cantonese, Hindi, Punjabi, and Urdu. Legal Aid Ontario is listed among the group's memberships.
