But he would fall under Interm conditions right as per the policy outlined below:
Eligibility requirements for interim authorization to work
In addition to meeting the eligibility criteria for the work permit, a former work permit holder who converted to visitor status may also be eligible for interim authorization to work if they meet
all the following:
- have valid temporary resident status at the time of work permit application submission
- held a valid work permit in the 12 months preceding the date on which they submitted their application for a work permit under this public policy, even though they are now only a visitor
- intend to work for the employer and occupation specified by the LMIA or LMIA-exempt offer of employment included in their work permit application submitted under the public policy
- have applied to IRCC for the interim authorization to work as per this public policy using the IRCC Web form
- have requested that the authorization to work be applicable until a decision is made on their work permit application
- will remain in Canada throughout the period during which their work permit application is being processed
Basically he just need a job offer letter.
