Hiring an employee with a student Visa

Hi, We are considering hiring an international student who holds a Canadian Study Permit & a Canadian Work Permit both of which expire on July 30, 2021.  We are located in Alberta, he would be doing oilfiled heavy labor work.  Is there anything that we should be aware of?  Any tips that you can provide in reference to hiring an international worker would be appreciated.  Thanks, Polly
