From the Canadian Weather Guru - Environment Canada:
"..Could this be snow-mageddon?..
Environment Canada is generally not prone to exaggeration unless there is deemed to be a real threat. We evaluate weather information and prediction models in a measured, scientific manner and couple that with overall impacts for significant events.
Mother nature from time to time will line up a near perfect set of conditions that generate a series of significant events. That time appears to be the coming week or so for many portions of southern Ontario in the form of snow storms. There appears to the right balance of sufficiently cold air in place, with Arctic highs to the north and a storm track along the lower Great Lakes. The term 'snow-mageddon' is not meant to alarm anyone or make light of the situation, but to highlight the cumulative effects and impacts that a series of snow storms can have on a wide region.
Total accumulations from the Wednesday, Friday and Sunday events may reach 50 centimetres in some areas. The cumulative effects of these three storms will make travel over this pre-Christmas period very difficult at times."
If Environment Canada is calling for "Snow-mageddon" (we actually prefer snow-pocalypse here) then I'm pretty sure we're in for it!
