Ãƒâ€šÃ‚Â§ 950-406. Parking and standing during major snow storm conditions.
In Toronto the Municipal Code Chapter 950 deals with traffic and parking. And subsection 406 appears to talk about snow storm and streetcar parking.
Where exactly did you park your vehicle?
Also MTO doesn't collect the fines for parking tickets unless they have gone into default and the city has filed a request to have your licence plate renewal denied. If this just happened recently then MTO wouldn't necessary have a record of any ticket that was issued, so you may wish to double check with the city to make sure there isn't a ticket issued against you. You can do that by calling parking tag operations at 416-397-TAGS(8247).
