About Ali Lawyers (Ayoub A. Ali Professional Corporation)

Ayoub A. Ali Professional Corporation, which still does business as Streetsville Law Office, is a small law firm based in Mississauga, Ontario. Its history goes back to 1968, when Andrew Stabins opened a general law practice in the village of Streetsville. Stabins ran the firm until retiring in 2006, when Ayoub Ali took over as principal. The firm has kept the Streetsville name even though its office has since moved to a different part of the city.

Ali is a lawyer and notary public, and a member of both the Law Society of Ontario and the Canadian Bar Association. Ali's law degree comes from Western University in London, Ontario, alongside a Bachelor of Science from the University of Toronto and a Master of Science from the University of British Columbia, an unusual pairing of science training with a law career. The firm's work covers corporate and business agreements, residential and commercial real estate transactions, wills, marriage and separation agreements, estate planning, and probate and estate administration counsel for executors.

The neighbourhood

The firm's current office is on Argentia Road, in Mississauga's Meadowvale Business Park. It's a mostly commercial and office district, home to office buildings, warehouses, and some of the area's bigger retail names, rather than a residential neighbourhood.

That's a change from a former address in the historic village of Streetsville. As of a 2023 site archive, the firm's office was at 95 Queen Street South, Unit B, in Streetsville. The firm still calls itself Streetsville Law Office, keeping that name even though today's address is in a newer part of the city.
