About Steinberg Law

Steinberg Law is the sole practice of Michael S. Steinberg, a Toronto barrister and solicitor called to the Ontario Bar in 1975. Steinberg holds a J.D. from the University of Toronto (1973) and a B.A. (Honours) from the University of Manitoba (1970). The practice is concentrated entirely on real property assessment and taxation, advising property owners, business owners, tenants, property managers, developers, and municipalities across Ontario.

The firm's work centres on assessment appeals for commercial, industrial, and multi residential properties, along with tax exemptions, rebates, and commercial lease disputes tied to property tax. Steinberg has appeared before the Assessment Review Board, the former Ontario Municipal Board (now the Local Planning Appeal Tribunal), the Environmental Appeal Board, the Ontario Superior Court of Justice, and the Ontario Court of Appeal. Steinberg is also a frequent writer and speaker on property taxation and assessment topics, having lectured through the Canadian Institute and the Law Society of Ontario's continuing legal education program.

The neighbourhood

Steinberg Law's office is on Wembley Road in Toronto, a different setting than the downtown office towers many Toronto law firms occupy, in keeping with a practice that remains a single lawyer's operation focused narrowly on property assessment and taxation law.

Frequently asked questions

Does Steinberg Law only handle commercial property tax appeals, or can homeowners get help too?
Michael Steinberg advises property owners, business owners, tenants, property managers, developers, and municipalities on property assessment and taxation, though the firm's appeal work is concentrated on commercial, industrial, and multi residential properties.
What is the deadline to appeal an Ontario property assessment?
A bulletin on Steinberg Law's site notes that the deadline to appeal or request a reconsideration of a property assessment is generally March 31 of the tax year, and that an outstanding appeal from a prior year can carry forward as a deemed appeal for the current year without a new filing.
I received a Supplementary or Omitted Assessment Notice from MPAC. What does that mean?
According to a bulletin on Steinberg Law's site, MPAC issues these notices to retroactively add or increase an assessment for a completed improvement, a change of use, or a rezoning, sometimes going back a year or two. The bulletin explains that the additional assessment is only MPAC's opinion and can be challenged through the appeal process, though the statutory window to appeal is tight.
What courts and tribunals has Michael Steinberg appeared before?
Steinberg has appeared before the Assessment Review Board, the former Ontario Municipal Board (now the Local Planning Appeal Tribunal), the Environmental Appeal Board, the Ontario Superior Court of Justice, and the Ontario Court of Appeal.
Does Steinberg Law represent municipalities as well as property owners?
Yes. The practice advises property owners, business owners, tenants, property managers, and developers, and it also advises municipalities in Ontario on property assessment and taxation matters.
How do I reach Steinberg Law?
The office is at 49 Wembley Road in Toronto. Michael Steinberg can be reached by phone at 416.557.7781 or by email at mss@steinberglaw.ca.
