I moved to Canada from US end of 2020. I was receiving long term disability payments from my prior job/ Insurance. Is that considered foreign income? Where does it fall?

That was my only source of income for 2020. I started taking the Real Estate course during this time and am still continuing it now. I started some side gig jobs at the beginning of 2021, but nothing in 2020 as far as that goes.
New to filing tax in Canada.
Yes, I am a Canadian and US citizen and my residence is in Canada.
