If you are in Canada, you are covered.
If you are in US you may not have much choice. Again it depends on your status and income. If you are a US citizen, you should apply for medicaid. Green card does not qualify for medicaid.

One advice to you: Even if you don't have insurance, please get insurance for AT LEAST school going kids. You never know what happens. I have faced that when I was in graduate school. That time I didn't have insurance for my family members. Later I look insurance for only school going child.

Hope, something will come up to cover it.
