O.N.S.C. - Ontario Superior Court of Justice (Canada)

Related Citation: ONCA, O.N.C.J.


The Superior Court of Justice is Ontario's equivalent of British Columbia or Nova Scotia's Supreme Court or, for those provinces which call their most senior first-level court using the word "Queen's Bench".

Ontario has a history of renaming its courts every decade or so.

The latest incarnation, circa 2010, is the nomenclature of the Ontario Superior Court of Justice for which the legal citation is ONSC.

ONSC cases can be found on the Internet following this link.

The official website for the court (at least, until the next name change!): is here.
