Huh? The official site/Environment Canada are the best and most accurate. With the coastal weather, anything more than a few days out is more of a trend than an accurate forecast temp/snowfall wise. What env canada says for the following day or two is usually very accurate.
Snow-forecast is decent, but if you compare it 5 days out to what acually happens, it is often quite different. It's useful for seeing when big storms are coming and freezing level patterns though (as is radar). It also overpredicts snowfall for the alpine and always predicts colder temps than actually happen.
