In moving here, we are not allowed to keep our OHIP coverage - our health care plan in Ontario. We get it upon moving back (after we have been back in Ontario for 6 weeks; it's not like you can just drive back across the border and suddenly you are covered again), and we are only granted emergency short-term coverage now if we were to fall ill while visiting or traveling in Canada.
In making the choice for my husband to accept this assignment here, we had to make a very careful comparison of the health care plans available to us. We picked the most expensive and comprehensive one offered.
I could share more, but any long-term medical condition requiring the regular use of medication costs at least 50 - 75% more to manage here in the US. I gave my example earlier - one asthma inhaler - $90 vs $260. With a 20% co-pay, that inhaler still costs me $52 here vs $18 in Canada.
It feels almost dangerous to be here if you had no coverage.
Sometimes I think most people who oppose the concept of UHC are people who have never been ill.
