Canadian Legal Citation Builder

Format structured Canadian legal citations using the McGill Guide, 10th edition style.

Independent, browser-based helper for common Canadian source types. Nothing you enter is stored or transmitted. Verify every citation against the current guide and any faculty, journal, or court instructions.

How to use this tool

  1. Pick a source type at the top. The form updates to show only fields for that type.
  2. Fill in the metadata you have. Required fields are marked; leave optional fields blank if you do not have them.
  3. Read the Footnote citation and Bibliography entry panels. The Citation anatomy list shows exactly what the tool used.
  4. Copy the output, then verify every element against the current McGill Guide and your course, journal, or court rules.

The tool never invents metadata. Missing fields are flagged as warnings, not silently filled.

Type party names as you want them to appear. Italics are applied automatically.

Paragraphs and pages are formatted differently. Choose the correct type on the left.

Formatted citation

  • Style of cause is required.
  • Provide a neutral citation, or a reporter with year and first page. Otherwise the citation cannot identify the case.

Verify the output against the current edition of the Canadian Guide to Uniform Legal Citation before submitting. This tool does not guarantee academic acceptance or exhaustive compliance.

Footnote citation
Fill in the required fields to generate a citation.
Bibliography entry
Fill in the required fields to generate a citation.
Short form

Short forms depend on how the case is first introduced and later referenced. Choose a distinctive short form manually and confirm it matches your school or court's requirements.

Citation anatomy

Fields you enter will appear here so you can check each component.

Privacy and academic integrity
Formatting runs entirely in your browser. Your citation data is not saved or sent to any server. This tool assists with mechanics only. You are responsible for source accuracy, academic integrity, and compliance with your school, court, or journal rules.

How this builder assembles a citation

The builder is deterministic. It takes the metadata you type into the form, selects the template that matches the source type you chose, and joins your values with fixed separators in a fixed order. The same inputs always produce the same output, on any device, with no randomness and no ranking of alternatives.

Nothing is fetched, looked up or inferred. There is no artificial intelligence in this tool, no scraping of court or publisher databases, no authority lookup and no attempt to complete a field you left blank. If a field the template expects is empty, the builder raises a warning beside the output instead of inventing a plausible value. A citation assembled from partial metadata is still incomplete metadata, arranged neatly.

The three stages

  1. Collection. Only the fields belonging to the selected source type are read. Switching type changes which fields the template consumes.
  2. Normalization. Surrounding whitespace is trimmed and author or editor entries you separated with semicolons or new lines are split into a list. Your wording, spelling, capitalization and accents are preserved exactly.
  3. Assembly. Values are placed into the template, the anatomy breakdown shows which field became which segment, and warnings list every expected field left empty.

The anatomy panel exists so you can audit the output rather than trust it. Read it field-by-field against the source document in front of you.

The eight source types this builder supports

These eight templates are the entire scope of the tool. Anything not on this list is unsupported, and the builder will not produce a citation for it.

Source types supported by the citation builder and the metadata each template consumes
Source typeMetadata you supplyWhat the builder outputs
CaseStyle of cause, neutral citation or year, reporter volume, reporter, first page, court, jurisdiction, paragraph or page pinpoint, URLA single-line case citation with your pinpoint appended in the position the template defines
StatuteTitle, jurisdiction, statute volume, year, chapter, section pinpoint, URLA statute citation ordered title, volume, year, chapter, then section pinpoint
RegulationTitle, jurisdiction, designation, number, section pinpoint, URLA regulation citation ordered title, designation, number, then section pinpoint
Journal articleAuthors, article title, year, volume, issue, journal, first page, pinpoint, URLAn article citation with the title quoted and the journal details following it
BookAuthors, title, edition, place, publisher, year, pinpoint, URLA book citation with publication details grouped in parentheses
Chapter in an edited bookChapter authors, chapter title, editors, book title, edition, place, publisher, year, first page, pinpoint, URLA chapter citation linking your chapter to the edited collection
Website or online documentAuthors or organization, title, publication date, URL, access dateAn online-source citation ending with the URL and, if supplied, the access date
Government reportAuthors or organization, title, publication details, date, URLA report citation with the issuing body carried in the author position

Required metadata varies by template. The warning list under the output is the authoritative statement of what a given template wanted and did not receive.

What you must verify manually

The builder handles first-reference, long-form citations in the eight templates above. Everything below sits outside what the templates do, and you must draft and verify it yourself against the citation guide your faculty, journal or court requires.

  • Short forms and subsequent references, including the bracketed short form you introduce on first reference and every later cross-reference.
  • Bilingual and French-language conventions, including French punctuation, spacing and the treatment of translated titles.
  • Québec materials and other civil-law sources with volume and compilation conventions the templates do not model.
  • Treaties, international instruments, decisions of international bodies, and parliamentary or legislative-history materials such as debates, bills, journals and committee evidence.
  • Loose-leaf services, legal encyclopedias, and Indigenous legal sources, including oral histories and the citation practices particular communities and courts expect.
  • Parallel citations, subsequent history, and any requirement to cite a specific reporter series or database version.
  • Institutional variants: your professor, journal or court may require capitalization, italics, punctuation or ordering that differs from the template output.

Italics and small capitals are typographic choices that live in your word processor. The builder emits plain text, so styling case names, statute titles and book titles is your responsibility after you paste.

Two short workflows

Fictional teaching example — not legal authority.

Workflow one: a case with a paragraph pinpoint

A student has an invented appellate decision in front of them and enters: style of cause Aster v Borealis, neutral citation 2099 FICT 1, court noted as the fictional appellate court, paragraph pinpoint 14. They leave reporter, volume and first page blank, because the invented decision has no reporter.

The output is a single line assembling those four values in template order, and the anatomy panel lists them as style of cause, neutral citation, court, paragraph pinpoint. The empty reporter fields raise no warning, because the template treats reporter details as an alternative to the neutral citation rather than a requirement.

Verification step: the student opens the decision, confirms the party names and the paragraph number carry the proposition they are citing, and applies italics to the style of cause in their word processor.

Fictional teaching example — not legal authority.

Workflow two: a journal article with a missing field

The student enters an invented author, an invented article title, the journal name, and a pinpoint page, then forgets the year and the first page of the article.

The builder still assembles the segments it has and shows two warnings naming the year and the first page. It does not guess either value, and it does not describe the result as complete. The student returns to the article's first page, reads the missing details off the source, enters them, and rebuilds.

Verification step: the anatomy panel is compared line by line against the printed article header before the citation is pasted into a footnote.

Where to go next

  • Run the assembled citation through the Citation Checker for a narrow mechanical screen. A clean screen is not a statement of compliance.
  • Collect verified citations into the Table of Authorities Builder once each one has been checked against its source.
  • Re-verify anything you carried over from an earlier draft, since a citation copied forward is a citation nobody has read recently.

Privacy, academic integrity and independence

Privacy on this page. Every field is processed in your browser by the page's own JavaScript. The builder makes no server request with your metadata, puts no field content in the page URL, and sends no field content to analytics or logs. Your entries live in page memory only: reloading the page or pressing Reset discards them, and nothing is saved between sessions. If you copy the output or print the page, that content is exposed to your own device's clipboard, printer and print-to-file destination.

Academic integrity. The builder arranges metadata you already have; it never verifies that the source exists or that it supports your proposition. Citing a source you have not read is an academic integrity problem no formatter can solve, and no output here is certified, official or guaranteed compliant with any citation guide.

Open source attribution

This tool is an independent implementation. It does not reproduce text, examples, or rules from the Canadian Guide to Uniform Legal Citation, 10th edition. The name is used only to identify the target style.

The tool formats citations from the fields you enter. It does not import a Citation Style Language (CSL) style file, and it does not read or write Zotero libraries. For reference, community-maintained CSL styles are catalogued in the Zotero Style Repository and described in the Zotero CSL documentation.

Output follows one target style only. If your course, journal, or court requires the Canadian Open Access Legal Citation Guide (COAL) or any other style, format those citations from that guide directly rather than from this tool.
