About M0 Law Office

M0 Law Office is a small general practice based in Toronto, Ontario, run by Mosun Oguntunde, a Barrister, Solicitor and Notary Public. Oguntunde was called to the Nigerian Bar in 1993 and to the Bar of Ontario in 2014, and is a member in good standing with the Law Society of Ontario, licensed to practice in both Ontario and Nigeria.

The firm describes its focus as real estate and immigration law, while also taking on wills, powers of attorney, and notarial and commissioner work. On the real estate side, it acts on residential, commercial, and cottage purchases and sales, along with mortgage, refinancing, and lease transactions. The immigration practice covers permanent residence applications, including the Express Entry, provincial nominee, and family sponsorship streams, temporary resident applications such as study and work permits, and appeals to the Immigration Appeal Division and the Federal Court.

Beyond a law degree, Oguntunde holds a Master of Social Work from the University of Warwick in the UK and is a Registered Social Worker in Canada, alongside an LL.M and LL.B.

The neighbourhood

The office is in a mixed office and residential tower at Jarvis and Carlton Streets, built in the 1980s, where the ground floor holds residents' amenities such as a pool and squash courts rather than a typical office lobby. The building faces Allan Gardens across the intersection, a park bounded by Carlton, Sherbourne, Gerrard, and Jarvis Streets that opened to the public in 1860 and today holds a domed conservatory built in 1909 in the Edwardian style. The address sits just west of Cabbagetown, a downtown Toronto neighbourhood known for its blocks of 19th century houses, and is a short walk from College subway station, with the 506 streetcar running along Carlton Street.
