Apparently not true. My understanding is that PetroCan Ultra 94 has ethanol.
From their website:
Ethanol-blended gasoline
Ethanol-blended gasoline is a fuel that typically contains up to 10% ethanol in unleaded gasoline. We use ethanol in our gasoline where legislation requires its use and where conditions warrant. The Federal Government has regulated that motor gasoline sold in Canada after Sept. 1, 2010 must contain an annual pool average of 5% ethanol. Different provincial mandates also exist, some with higher ethanol pool requirements.
Because of these mandates, most grades of Petro-Canada fuel may now contain up to 10% ethanol. This represents a change from the previous state, where premium fuel was ethanol-free at Petro-Canada. To find out if ethanol-blended gasoline is sold at a station look for the yellow labels in the pump area indicating that the fuel may contain a maximum of 10% ethanol.
