I'm sorry, but the other responses to this thread are incorrect.
"i have received admission for phd "
Am I correct in assuming that you've been admitted to a Canadian university? If I am, then the answer is
no. You've been admitted to a Canadian university as a PhD
student. This is not an offer of employment. Also, IRCC has a very specific requirements for what can or cannot be considered a valid offer of employment (job offer).
