Ethanol blends: 10% in "reg." gasoline, 5% in mid-grade, 0% in premium (in Ontario)

I read this today - it's the first time I'd ever come across this info:

Quote:
Gasoline sold in Ontario is required to have an overall ethanol content of five per cent.

But, as not all engines can tolerate it, you'll typically find 10 per cent ethanol in regular gas, five per cent in mid-grade, and none in premium grades.
From "Most gas has enough ethanol to act as gas-line antifreeze" - Toronto Star, Feb 06, 2010 , by Eric Lai

I mean, I knew about the 5% blend law for Ontario. But the rest of it seems somewhat fishy. Has anyone else heard of this blending approach before if there's mandatory ethanol blending where you live?

Considering I only put about 5 or 6 tanks through the Flea each year, if that's true, maybe I'll start springing for the good stuff!
