There are 2 aspects to sponsorship:
1) It allows your family member to immigrate to Canada and get PR.
2) It requires you, as an individual to make a commitment to provide for basic needs and to support that person financially
To sponsor a family member, you are required to meet several requirements such as being:

• a Canadian citizen or permanent resident of Canada
• 18 years of age or older
• able to support the sponsored person for several years

Canada aims to welcome over 1,00,000 family class immigrants each year. Canada is pursuing the highest levels of immigration in its history to support its post-covid economic recovery.
