Alexander Ostroff is an appellate associate at Lockyer Campbell Posner. In 2014, he graduated from the transsystemic program at the McGill University Faculty of Law in 2014, with degrees in both common law and civil law.

In law school, Alexander worked with the Center for Research-Action on Race Relations on cases of discrimination and racial profiling by law enforcement, and on related complaints to the Québec Human Rights Commission and the Commissaire à la déontologie policière. He also co-developed the Faculty’s first Critical Race Theory course, and co-organised a public panel on criminalization of HIV non-disclosure. These experiences strengthened his interest in criminal law and his commitment to the pursuit of justice.

Alexander was called to the Ontario Bar in 2015. In 2016, he joined Lockyer Campbell Posner, where his practice focuses on criminal appeals. He speaks fluent French, and has a working knowledge of Spanish.


As an appellate associate at Lockyer Campbell Posner, Alexander represents clients appealing their convictions and sentences, as well as clients responding to Crown appeals. He appears regularly at the Court of Appeal for Ontario, both for his own files, and while working with senior partners on complex criminal appeals. In R. v. Wisdom, 2017 ONCA 650, Alexander assisted James Lockyer in a successful appeal of convictions for first degree murder and attempted murder for the benefit of a criminal organization, after which the Court of Appeal ordered a new trial. In R. v. Davies, 2017 ONCA 467, Alexander persuaded the Court of Appeal to reduce a lengthy robbery sentence by two years.

Although his practice focuses on criminal appeals, Alexander has also argued appeals at the Ontario Court of Justice, where he obtained a new trial for a client convicted of multiple provincial regulatory offences. He also prepares summary conviction appeals, Supreme Court leave applications, applications for bail pending appeal, and has successfully obtained Court-ordered funding for appeals denied funding by Legal Aid Ontario.

Prior to joining Lockyer Campbell Posner, Alexander articled at the Crown Law Office – Criminal, where he developed appellate advocacy skills working on murder, manslaughter, assault, firearms and drug appeals, as well as inmate appeals and a Supreme Court of Canada intervention. He also assisted senior counsel on complex prosecutions of police officers, and conducted trials and appeals of provincial offences at the Ontario Court of Justice in both English and French.
