First, the good news: McDonald's Canada is adding a Skor McFlurry to its menu, which sounds delicious.
But, bad news: It turns out that's a really bad thing for anyone with peanut or tree nut allergies.
And now people are pretty pissed off.
For parents of kids with deadly nut allergies, McDonald's had been a safe place to bring their family to eat.
It also means having yet another thing to worry about when their kids are out of their sight.
Not to mention adults with nut allergies.
The McDonald's announcement also said they "have a long history of being sensitive to the needs of our guests with food allergies." But people are wondering how that can be true given the changes.
Many people on social media have already said they'll stop going to McDonald's because it's just not worth the risk.
And considering how common and severe nut allergies are, it seems they stand to lose a lot of customers.
Although McDonald's Canada has made no mention of the nut issue on their social media accounts, their mentions and comments are now flooded with angry messages.
McDonald's has not replied to the upset customers directly, but said in their announcement information about the changes would would be shared "in restaurant, at the drive-thru, on our website and through our mobile app."
