Mr. Caron, your question touches on the general logic of this measure and the changes from 2013 and 2016. It is logical to determine whether it is preferable to clarify these definitions in the context of regulations or an act, or even on the basis of the case law.
In this case, we have implemented the government's platform very faithfully in order to reverse changes that were made in 2013. The tendency is to revert to case law, as a basis, to clarify these definitions.
That said, I will continue in English and consult my notes in order to give you a more specific answer to your question.
The reasonable interval refers to the period starting when a claimant has become unemployed to the time that subsequent employment was offered to the claimant. This is only for employment to be considered suitable when it falls outside a claimant's usual occupation or at a lower wage scale.
A reasonable interval is not a fixed period, and it varies according to the circumstances. Case law has provided some guidance in determining a reasonable interval through the circumstances of each particular case, with factors including an active job search, consideration of reduction in salary, drastic change in occupation, shortage of work, but as a general rule, case law has held that essentially two to three months is a reasonable period of time before a claimant needs to be more flexible and less restrictive in determining a suitable employment.
To conclude, it's a case-by-case approach.
