Jeez, that sounds like an awfully long holdover time for freezing drizzle - if I remember correctly, the HOTs published by Transport Canada only allow a HOT of something like 2 to 5 minutes for this condition. I don't have access to those documents right now, I'm just going from memory, so I might be wrong... but I kind of suspect that 40 minutes might be a bit optomistic.
