Our frying oil is different, therefore trans fat levels are lower than the US, and the oil does not contain the flavouring mentioned, or any wheat or dairy derivatives.Too bad that wasn't contained on the company's Canadian website next to the promotional bumpf.
Hunt around and you can find an "electronic press kit" website for McDonald's Canada. That site contains information on a "nutritional" packaging initiative that starts in March 2006. The information doesn't contain anything on ingredients other than for things like fat and fibre.
That site doesn't contain the fries statement either, nor was the statement carried on Canada Newswire, a news release distribution service. You will find stuff supporting the company's marketing initiatives though.
The case is still in the Homer Simpson file.
