This includes different scenarios:
Implied Status and Travelling Outside Canada:
Such people are allowed to come to Canada again as temporary residents till a decision is made about the renewal of their work permit application and are TRV exempt as per R190 or on a multiple-entry visa. However, they are not allowed to start or resume their work in Canada until a decision is reached about the renewal of their work permit. This also applies to foreign nationals who are TRV exempt as per R190(3)(f) and those on multiple-entry visas).
Extensions:
Once an extension is granted the date of acceptance will be shown on the document. In case the extension is refused, the person will be considered under implied status till a decision is reached about their work permit extension. If the extension is all together rejected, the client will be considered under implied status till the TR document expires. A second document can be presented if the first one is rejected. In this case, the status on the second document will be the new status.
