Actually the instructions do mention it.
The
guide says:
Results from a third-party language test
NOTE: If you did the test in the past for immigration or citizenship purposes, we will accept the results even if it has expired.
- Canadian English Language Proficiency Index Program General Test (CELPIP-G) or the CELPIP-General LS (listening and speaking).
- If you took the test after April 1, 2014, you must have a score of level 4 or higher in listening and speaking.
- If you took the test before April 1, 2014, you must have a score of 2H or higher (i.e., 3L, 3H, 4L, 4H, 5L, or 5H) in listening and speaking.
- International English Language Testing System (IELTS), General Training. You must have a score of:
- 4.0 or higher in speaking and
- 4.5 or higher in listening. (Note: If the test was done before November 28, 2008, we will accept a level 4 or higher)
- Test d’Évaluation de Français (TEF), Test d’Évaluation du Français adapté au Québec (TEFAQ) or TEF pour la naturalisation.
- If you took the test afterJuly 1, 2012:
- Niveau B1 or higher, (i.e. B2, C1 or C2) in Compréhension de l’oral and Expression orale
- If you took the test beforeJuly 1, 2012:
- Niveau 3 or higher in Compréhension de l’oral and Expression orale.
- If you took the Test d’Évaluation de Français (TEF) before July 1, 2012, you need a level 3 for expression orale only. This applies only to the TEF and not the TEFAQ or TEF pour la naturalisation.
- We will accept the following proof if you have submitted them in the past for immigration purposes to Quebec(note: these tests align with the échelle québécoiseand not officially with CLB/NCLC 4):
- Diplôme approfondi de langue française (DALF) – All test results
- Diplôme d’études en langue française (DELF) – Level B1 or higher
- Test de connaissance du français(TCF) – Niveau B1 or higher
- Test de connaissance du français pour le Québec (TCFQ) – Niveau B1 or higher
In other words they accept expired results as long as you have used them for immigration purposes (such as Permanent Residency) in the past. If people don't have copies of their results from the tests they took a long time ago, there is always the option of taking a new test or submitting another proof like a diploma.
Not sure what you mean by this, but they have clear operational instructions and guidelines. You can read more about them
