Your sponsorship eligibility is based on income of year 2016, 2017 and 2018. If your application is not completed by dec 31st 2019, then in 2020 you are required to meet income cut off for 2019 as well. EI income (except special benefits which is parental EI) cannot be counted towards 2019 income for cut off. so EI is not the issue, your issue might be not meeting 2019 cut off in 2020 IF your application is not completed by Dec 31st 2019. If you already have enough income for 2019 to meet the cut off then really nothing to worry about.
Sorry about the job loss. Hope something comes up soon.
Really appreciate your quick response. already met the 2019 criteria. hopefully the application will be completed by dec 2020. my concern is what would be my reply if they ask top prove the meeting of requirements for 2020. or if they asked about employment status.
Also my main question was would applying for EI be considered as taking social assistance. the reason why I'm asking this question is because I remember in sponsorship application it said that until the approval of Permanent residence of parents you should not be taking social assistance. would EI be considered as social assistance?
