Under Canadian laws, you may sponsor your wife, husband, common-law spouse or conjugal partner to come to Canada and join you under the Family Class. Generally speaking, it should be noted that income requirements applicable to other sponsorships, such as sponsorship of parents and grandparents, do not apply when you are sponsoring a spouse, common-law partner or conjugal partner. Therefore, regardless of your income, you can sponsor your wife, husband, common law or conjugal partner, and dependent children for immigration to Canada.
Under the new immigration laws of Canada, there is no longer any provision allowing sponsorship of fiancé. This law changed as of June 2002 and under the new system, you must first be married before sponsoring your spouse.
The same general rules regarding sponsorship of a spouse also apply to the sponsorship of an orphaned brother or sister who is still a minor. Sponsorship of orphaned brothers and sisters fall under the same general category as sponsorship of nephew or niece, grandson or granddaughter, if he or she is an orphan, under 18 years of age and not married or in a common-law relationship.
