AI321,
I don`t know about Canada, I last saw that maybe like 5 or 6 months ago nd it was still limited to -3.5, if it changed since then I don`t know.
I also checked the Israel CAA had a -3.00 but when I wrote them to ask if I had an FAA class 1 if it would be a problem there and they siad that if I pass the FAA class 1 I would pass their Class 1 too.
Mexican CAA has not changed their regulations on medicals since like the 50s and it still is limited to -3.00.
Best,
Arturo
