That site doesn't claim that they aren't actually gluten free. What it does claim is that the data General Mills provided has not convinced the Canadian Celiac Association that the process for verifying that that there was no cross contamination was not rigorous enough. That is good info, but starting off with "Cheerios aren’t actually gluten free" is simply not true. My family has not had any issues due to any cross contamination with them (we would know immediately), but this does make me want to cut it out as the risk is simply too high. Thanks for the heads up.
