One of the bigger coastal and valley snow events in British Columbia is on the way. Snow will spread over the coast during the day Tuesday, reaching the Vancouver area toward the end of the day.
Snow will be heavy at times Tuesday night into Wednesday morning.
Snow will change to rain from west to east during the morning Wednesday starting on Vancouver Island then spread into the Fraser Valley, but not before a significant amount of snow falls.
Here is a rough estimate of what I see for potential snowfall through Wednesday.....

Snow for Ontario Tuesday and Tuesday night
A much weaker storm will bring accumulating snow to parts of Ontario later Tuesday and Tuesday night.
The track of the upper-level energy with this storm is favorable, but moisture will be limited. However, it is cold, so snow will have no problem accumulating right off the bat.
There may be some lake enhancement from Hamilton, Ontario, on south, which could bring some localized higher amounts.
A strong, secondary coastal storm will bring heavy amounts of snow from Connecticut to northern Rhode Island and Massachusetts from Boston on west on Wednesday, then it could get up into Nova Scotia after that.
