WHEN AND HOW OFTEN TO CITE
- Statutes: Footnote the first instance of each statute in each chapter. Use a short form of the statute title for subsequent references in the chapter. Subsequent references do not need a footnote, unless there is reference to a specific section (i.e., a pinpoint reference), and the reference is not integrated into the running text. College titles generally mention the section referred to in running text, and practice titles can handle more footnotes than college titles.
The Mutual Legal Assistance in Criminal Matters Act6 allows Canada to collect fines7...
6 Mutual Legal Assistance in Criminal Matters Act, RSC 1985, c 30 (4th Supp) [MLACMA].
7 MLACMA, s 9.
In the following example, the Criminal Code has already been cited, and the section reference is in the text, so no footnote is needed.
Section 684 of the Criminal Code states: “A court of appeal or a judge of that court may, at any time, assign counsel to act on behalf of an accused.”
Even if a case name is mentioned in the running text, include the name and the citation in the footnote.
[running text] ... the common law test established in Dagenais v Canadian Broadcasting Corp7 is used.
[footnote] 7 Dagenais v Canadian Broadcasting Corp,  3 SCR 835, 94 CCC (3d) 289.
[running text] ... unless the opposing party can satisfy the common law test established in Dagenais v Canadian Broadcasting Corp.22
[footnote] 22 Supra note 7 at para 9. [No need to repeat case name; see discussion of supra references below.]
Use ibid to refer the reader to an immediately preceding reference. Use only if the antecedent is very clear. That is, if there’s only a single reference in the antecedent footnote. If there is more than one, use supra. See examples below.
However, given the Supreme Court of Canada’s pronouncement in St-Cloud10 that an .... Wagner J held “he or she might take account of the fact that the trial of the accused will be held at a much later date.”11
10 R v St-Cloud, 2015 SCC 27,  2 SCR 328. 11 Ibid at para 71.
Use supra to refer the reader to a reference containing the original, complete citation. Repeat the case or source name if it’s not mentioned in the running text, or if there is more than one citation in the note to which the reader is being referred. In the first example, even though Toronto Star Newspapers Ltd v Canada is mentioned in the preceding note, an ibid reference might cause confusion because there are two citations in the preceding note. The case name is repeated for clarity as well. In the second example, there’s no need to repeat the case name because it is mentioned in the running text.
Section 517 was held to be a justifiable limit on the right to freedom of expression guaranteed by section 2(b) of the Canadian Charter of Rights and Freedoms.18 The pressing and substantial objectives of section 517 are to safeguard the right to a fair trial and to ensure expeditious bail hearings.19 [footnotes]
18 Toronto Star Newspapers Ltd v Canada, 2010 SCC 21,  1 SCR 721 at para 61; Canadian Charter of Rights and Freedoms, Part I of the Constitution Act, 1982, being Schedule B to the Canada Act 1982 (UK), 1982, c 11 [Charter].

... an obligation to be full, fair, and frank in the application.13... have the extradition proceedings stayed, as was argued in Tollman.47 [footnotes]
13 USA v Tollman (2006), 271 DLR (4th) 578 at para 135 (Sup Ct J).
47 Supra note 13.
Use infra to refer the reader to a subsequent reference. Not very common, but used when a case is first mentioned simply in passing, and is discussed more fully later on in the text. An “infra” reference can be used at the first mention.
An additional reason to undertake such a process is to cause the immediate cessation of any offensive behaviour.2
2 As in Harriott v National Money Mart, infra note 15.
[running text; later in chapter]
The HRTO made a similar finding of a failure to properly investigate in the case of Harriott v National Money Mart.15
