My wiper fluid freezes. What am I doing wrong?

Yesterday it was -6°C in Montreal. I used the windshield spritzers to spray wiper fluid on my windshield. The thin layer of fluid immediately froze, rendering the windshield opaque until I could get it warmed up with the defroster. This happens regularly. It even happens after the windshield is clear of ice. I'm using regular windshield wiper fluid that' supposed to be good down to -40°. Am I doing something wrong, or is -40 a huge fib?
