Yes. The government of Canada permits permanent residents and citizens of Canada to sponsor their family members, including sisters to Canada. This is possible under its Family Sponsorship program.

However, here are some requirements you must fulfil to become a sponsor –

• 18 years of age or older.
• Must be a permanent resident or citizen of Canada.
• Have enough money to provide basic amenities to your sister once she is in Canada.
• Not getting any help from the Canadian government, except in the case of any disability.
• Must have a low-income threshold.
• Prove your relationship with your sister through proper documentation.
• Currently living in Canada.
• Must follow all Quebec laws, if living there.

Make sure you have all the documents to show to the Canadian authorities to avoid any unnecessary delays or rejections.
