According to the questions that we received at the reference desk recently, there seems to be quite a confusion if a period (full stop/ dot) should be used at the end of the footnote when you are referring to a code. I contacted the editor of the Cite Guide, Alexander Max Jarvie, who kindly provided this clarification that I am sharing with you:
“The period that appears at the end of examples provided elsewhere in the Legislation section is intended as an indication of the terminal period for the entire citation. Although we have removed most periods from citation forms in the 7th edition, a citation footnote is still a sentence and as such punctuation is used in normal fashion. Hence, if the citation to a codal article is the last (or the only) source to be referenced within a particular footnote, a period would follow. To illustrate these rules in practice, I have provided examples below:
2 Art 1214 CCQ.
4 Canada Act 1982 (UK), 1982, c 11.
35 See Canada Act 1982 (UK), 1982, c 11; see also art 1214 CCQ.”
