In text, cite the name of the case (italicized) and the year of the decision.
e.g. (Vriend v. Alberta, 1998)
Reference form for cases:
There are multiple formats for Canadian Cases. Some examples are:
1. Reporters that begin at volume one each year, and are thus organized by year first, then volume number.
e.g. R. v. Morgentaler,  3 S.C.R.463
2. Reporters that are organized by volume only.
e.g. R. v. Moolla (M.) (2008), 310 Sask R. 254 (Sask. C.A.)
3. Neutral Citations
e.g. MacDonald v. Taubner, 2006 ABQB 138
4. Case citation to electronic systems
e.g. Doug Burns Excavation Contracting Ltd. v. Int'l Union of OPerating Eng'rs, Local 721, 1999 CanLii 1081 (N.S.S.C.)
The APA Publication Manual says: "References to legal materials...which include court decisions, statutes and other legislative materials, and various secondary sources, will be more useful to the reader if they provide the information in the conventional format of legal citations."( p. 216, para.1)
APA form for legal citations is based on The Bluebook: A Uniform System of Citation.
The examples in the APA Manual are all US cases.
However, when you go to The Bluebook, you find that the format for Canadian cases is slightly different.
There is are copies of the 19th edition of The Bluebook at the Education, Humanities & Social Sciences, and Law Libraries. Canadian pages are 298-303.

The examples in The Bluebook all have (Can) as the jurisdiction at the end of the case. It is not wrong to add it, but you don't need to - as you are in Canada citing Canadian Cases. (McGill Guide does not add it)

The standard book for Canadian citation is the Canadian guide to uniform legal citation, known as the McGill Guide.
The Bluebook refers to this item. Citing according to the McGill Guide would be well within APA standards, as that is the conventional format in Canada.
