Al and Linda,
No need to wait for Tuesday.
Check out the OHIP web site. Google 'ohip' and then go to the Fact Sheets section and look for Travelling. It tell you what OHIP will pay for no matter where you are.
Or type:
http://www.health.gov.on.ca/english/...ub/ohip/travel
In short, if it is available here and you choose to get it there, you pay.
You know you can deduct medical expenses from your income tax though. This would include items like this which you choose to have outside your provincial health care plan.
Good luck. Apparently they are costly because the half life of the isotope is very short. Where are you on the list in Ontario? Mt Sinai does some tests like that 7 days a week.
