To qualify for a work permit, you first need to find an employer who is willing to give you a job offer and that employer must then get an approved LMIA. Because the LMIA process is very long and expensive without guarantee of approval, it is generally extremely difficult to find employers who are willing to go through the process.
Look at Express Entry - FSW rather than trying to find a job since you have a Masters. You need to do an education assessment for your Masters and take IELTS for language.
Yes, she can apply for a work permit. If approved, she can work in Canada. She can't work until it is approved. Processing is probably over 30 weeks. Google - check processing times Canada - to check times. Does she have a visitor visa because you are asking about TRV?
Thanks. The issue here is, whether she leaves her company and apply for work permit in Canada, or can take a Leave without pay for a month or two so that if things don't work out at least job would be there back in India.
