Notice how the Airports (Toronto and Ottawa) are the lowest values on this list.   These also are the only weather stations on this list run by NAV Canada.   I don't believe that Ottawa had only 8 cms yesterday.  Not for a second.  I shoveled that snow and as far as I could tell there was definitely 10-15 cms.

 

Wrt to Toronto A/P, all around had least 16cms.  Mississauga, just a few kms down the 401 had 19cms.   I think there is a serious issue with the NAV Canada weather monitoring equipment.  Unfortunately, this is the data that goes into the official climatic record for posterity.
