I am US but have lived in Canada for quite a few years.
The cost for health insurance here is $120/month for wife and I, $135/month covers family with kids under 18, or as long as they are in school.
$67/month for single adults.
I have never had a major issue, knock on wood, and have heard all the stories of "goofs" in the system here, but what system run by people doesn't have "goofs".
Plus we have a 5% Federal Sales Tax, so 5% of your after income tax(which is higher here) money goes to fund this, as well as other things.
So that means you are paying approx. another $150/month per person
When I was in the US I was single and got high deductible medical insurance, it was through my State Farm agent, it was the highest deductible offered at the time, $1,500 in a 12 month period, if I remember correctly, it was $55/month, we are talking years ago.
It was basically catastrophic coverage, so I wouldn't lose house or other assets if I had an extensive medical issue.
