Look for the actual language label
The World Federation of the Deaf explains that sign language is not universal. Its position paper on International Sign also emphasises deaf people’s right to choose and access appropriate interpretation services. International Sign and a named national sign language should therefore not be treated as interchangeable labels.
Check the event or publisher description for the language or service offered. A spoken English soundtrack does not establish that the accompanying signing is American Sign Language, and a French interface does not establish that it is langue des signes québécoise.
Keep three access features separate
Identify spoken audio, written captions and signing individually. A video can have one, two or all three, with different languages represented. Captions in one language do not explain the signing language, while a signing window does not prove the presence of captions. Use the features actually listed for that recording rather than borrowing details from another event.
For a group viewing, ask participants which language access they use instead of choosing solely from a country flag. If the publisher lists International Sign, preserve that exact label in the invitation or viewing note.
Do not assess an interpreter’s language or qualifications by appearance. Use the organiser’s credit or service description when that information matters.
Verify the recording you will share
Some publishers provide separate interpreted recordings rather than a switch within one player. Open the correct edition and verify its description before sending the link. Record the event title, date and language-access label so a recipient can identify it again.
If the language is unspecified, report that uncertainty and look for a named accessible edition from the organiser. Do not promise universal comprehension or automatic conversion between sign languages. This is a selection task about language access, not a claim that any particular Canadian service carries the event. Keeping the publisher’s exact wording makes the limitation visible and helps each viewer choose an edition that suits them.
For a recorded conference, retain the accessible-edition link separately from the general event landing page.
