Section 4. Punctuation and Typography

 

Guidelines for proper punctuation and typography are covered in great detail in Chapters 6, 7 and 8 of The Canadian Style. Only key points and common questions are outlined below.

 

4.1       Dashes

The en-dash (–, MS Word: Ctrl+Num -) is longer than a hyphen and roughly the width of a capital N. It replaces the word “to” in a numerical range (as in “1974–1978”) and shows an equal relationship between two words (as in “East–West trade”). Its use between place names and to separate the date and time of events should be avoided. Rather, place names should appear as “from Montréal to Toronto” and event listings should appear as “March 7, 2 p.m.” There should be no space before or after the en-dash (but see “5.1 Exhibition Titles”).

The em-dash (—, MS Word: Alt+Ctrl+Num -) is longer than the en-dash and roughly the width of a capital M. It is used to show an abrupt change in thought, as a substitute for parentheses or to set off material for emphasis. The em-dash should be used only sparingly. Museum style is to use the em-dash with a full space before and after, which is an exception to The Canadian Style.

4.2       Commas

A serial comma should only be used when it is needed for clarity. In general, do not use a serial comma before the final “and” in a sequence unless one or more items in the sequence includes “and” or unless clarification is necessary.

Always place a comma before etc. as well as after the Latin abbreviations e.g. and i.e.  However, in popular texts, these Latin abbreviations should be avoided, in favour of English expressions such as “for example” or “such as.”

4.3       Colons, Semicolons and Obliques

A colon has many uses, the most common of which is to introduce a list, a statement or a quotation. It should be followed by only one space. The first letter after a colon should be capitalized if the colon is introducing a full statement, a new idea or a direct question.

Semicolons are often improperly used. In general, the semicolon either connects two sentences of equal weight or separates a series of items that contain internal punctuation. For detailed guidelines on the correct use of semi-colons, see section 7.24 in Chapter 7 of The Canadian Style. A semicolon is followed by one space only.

Do not put a space before or after an oblique (/) when it is used between individual words, letters or symbols. Put one space before and one space after an oblique if one of the elements contains internal spacing.

4.4       Quotation Marks

Double quotation marks are to be used for speech and for words used out of context. Single quotation marks are to be used for speech within speech. Periods and commas must appear within quotations marks; colons and semicolons must appear outside quotation marks.

4.5       Exclamation Marks

Exclamation marks should be used sparingly, and only when absolutely necessary. When overused, the exclamation mark becomes meaningless. A rule of thumb: if you would not shout the phrase, do not use an exclamation mark.

4.6       Italics and Emphasis

Use italics for book titles, works of art, song titles, movie titles, poems, plays, pamphlets, published reports, films, newspapers, magazines and other periodicals.  Also use italics for Native, French or foreign words or expressions that are not considered to be assimilated into the English language (such as caveat emptor). Do not use italics for words commonly used in English (such as ad hoc, kayak or igloo).

Do not use italics for emphasis. If a word, phrase or number requires emphasis, use bold font. Underlining should never be used for emphasis.

4.7       Spacing

Use only one space after any punctuation mark, including periods, colons, question marks, exclamation points, semicolons, etc.

4.8       Ellipsis Points

The use of ellipsis points should limited to indicating a missing segment of text in a direct quote. When presenting a non-exhaustive list of items, the sentence should be constructed so that the reader knows it is a sample list, but without ellipsis points. This could mean beginning your list with “such as” or “including,” or it could mean reworking the sentence so that it is clear that the list is meant as a sample. In formatted documents, spaced ellipsis points (. . .) are preferred over automatic ellipsis points (…).
