About The Law Firm of Abraham Jonas

The Law Firm of Abraham Jonas is a solo practice on Dundas Street West in Toronto's Little Portugal neighbourhood, run by Abraham Jonas, who was called to the Ontario Bar in 2010. Before opening the firm in 2015, Jonas spent five years at Saul Jonas in Toronto, working across real estate, family, estates, and corporate matters. The firm now handles residential and commercial real estate transactions, wills and estate administration, family law matters such as separation and custody, and corporate work including incorporations and shareholder agreements. Its pitch to clients is direct access: everyone who retains the firm works with Jonas personally rather than being handed off to a junior associate.

Jonas's path to law wasn't a straight line. Before the LL.B. from the University of Leicester in 2007, Jonas earned a Bachelor of Music Performance in French Horn from the University of Toronto in 2005. That combination of a performance degree followed by a UK law degree is an unusual one among Toronto solo practitioners, and it predates the decade Jonas has now spent building a general practice around real estate, estates, family, and corporate files.

  • Called to the Ontario Bar in 2010.
  • Worked at Saul Jonas in Toronto from 2010 to 2015 across real estate, family, estates, and corporate matters before founding an independent practice.

The neighbourhood

The firm's office sits on Dundas Street West in Little Portugal, also known as Dundas West, a corridor of vintage shops, cafes, and restaurants bordering Roncesvalles Village, Dufferin Grove, and Beaconsfield Village.

The office is a short walk from Dufferin Grove Park and Sorauren Park, and Lansdowne subway station is about eleven minutes away on foot, with route 505 Dundas bus service running along the same block. That puts the firm within easy reach for clients across the city's west end, whether they're coming in for a real estate closing or a family law consultation.
