I'm a Canadian living in the US married to a US citizen. I'm in the immigration process and haven't worked in Canada since winter of 2020. How do I file my taxes in CA?

I don't work in the US. I filed my Canadian tax return as a single person for the 2020 tax year. My husband and I file our taxes in the US, but with immigrating to the US I don't know how to legally file taxes in Canada
