When will I receive Canada child benefit

Hi everyone,

I have just returned to Canada in Jan 2020. I had a great overseas income in 2019 and based on the CCB calculator, it seems that I wont be receiving any CCB on my 2019 income. However, things have changed and now I'm unemployed. If I have no income in 2020, when will be the earliest time I start receiving CCB. Will it only be after July 2021 after the assessment of 2020's income? 

 

Also, given that I haven't worked at all in Canada for 2019, do I have to file taxes in April/May 2020? 

 

Thank you
