The tagging guidelines have one addendum to the NHS rule for motorways:

"Restricted-access, divided highways with two or more lanes in each 
direction, e.g. Highway 401 in Ontario, Autoroute 20 in Quebec, Gardiner 
Expressway in Toronto, Ontario."

Generally Ontario and Quebec are the only places that motorways may be, 
there are no highways in Alberta that meet the standard for instance. 
There are a number of ways in Saskatchewan that are mis-tagged currently 
that need to be fixed, but I believe that most of the Ontario ones are 
probably correct (I've never actually been to Ontario so I'll leave that 
to the people who know those highways best).
