Ok so through visitor visa She can visit for a short while like temporary but if she gets PR it would be a different affair
She may have difficulty visiting due to her strong ties to Canada. She will need to show she has strong ties to India that will require her to return to I did like a longterm job, property in her name, family who remains in India, etc. She also has to show that she has the savings to be able to afford the trip and it would help if she has international travel to other countries that are similar to Canada.
