Hi: I thank you for your responses. They do test in Ontario. Most
pediatritions and gastronolgists do. But if you want the health care
system to pay you have to go to a hospital to have the tests. McMaster
Medical Center and Toronto Sick Kids Hospital. When I went to my ped.
she said they would do the blood testing, all the ones I was advised to
do and 2 more which I am waiting to find out which, I will let you know.
