Medical insurance after work visa cancellation, during 30 days grace period

Hi, I am looking for some guidance.

I am currently employed but due to finish soon when my employer will cancel my work visa and medical insurance the same day, say 25th October. I will have 30 days grace period until 25 Nov to arrange for new employment visa or leave the country.

What medical insurance can I get in the visa cancellation grace period so that I am covered?
