Note: In most cases, there is no low-income-cut-off (LICO) for spouse, partner or dependent child sponsorships. However, if either a spouse or partner you’re sponsoring has as dependent child who has dependent children of their own, or a dependent child you are sponsoring has a dependent child of their own, you must meet a minimum LICO score, which is determined by the Canadian government each year.
If you must meet LICO requirements, you must include a Financial Evaluation (IMM 1283) form with your application (see your checklist for more details). If you live in Quebec, you don’t have to submit this form to IRCC. See subsection 1(3) of the Immigration and Refugee Protection Regulations (IRPR) for more information.
If you live in Quebec, you must also meet Quebec’s conditions to be a sponsor.
Note: Maternity, parental and sickness benefits paid under the Employment Insurance Act are considered income. You can still sponsor, if you’re eligible, while on these benefits. Other payments, such as employment insurance and federal training allowances, are not considered income.
