Urgent: Need information regarding sponsorship letter (Student Visa Process)

[AsmaRafiq]

Hello,

My name is Asma Rafiq. I am from Pakistan and I live in Sweden. Currently finished off my bachelor studies here
and now got admission to master studies in Canada.

I am about to apply for my student visa. However, my question is regarding "sponsorship letter". My elder sister
lives in Canada and is a citizen there and is married. She wants to sponsor my education and living expenses in
Canada. My question is,

If its okay to show my sister's sponsorship letter?

I have emailed the immigration office of Canada but haven't gotten a reply yet. I really need to know about this
information as soon as possible. If any of you have the answer to it then please help me out. Its urgent!

Regards,

Asma
