This.
And...
1. No one wants a new regulation forcing them do spend more money, even if it is mostly only a higher capital cost that will eventually be recovered through longer overall lifetime of both sets of tires. It comes down to setting a standard that strikes a balance. Winter tires are not only mandatory in Quebec, they are also required in Czech republic, Estonia, Finland, Germany, Lithuania, Latvia, Norway, Romania, Slovenia and Sweden from December thru March. Either the tire lobby is very effective, or these countries have come to a conclusion that requiring winter tires strikes a fairer balance between cost and safety.
2. The term "snow tires" is a misnomer. They are called "winter tires". M+S all-seasons have treads designed for snow, as do winter tires. The main benefit of winter tires is in the compound: it is optimized to grip better below 7 degrees. Many all-seasons are as good as plastic by -10 degrees. So whether it snows or not, the benefits will become more remarkable as the temperature dips below 7, and will be dramatically more remarkable below freezing especially if there has been precipitation. Sure, you can still drive with all-seasons even in the worst conditions. But realize that you may have doubled your stopping distance if you hit ice. I doubt most are compensating by driving 45km/h in 60k zones when it is an average chilly morning December thru March in GTA. And BTW, the 5% drop in deaths in Quebec is remarkable perhaps because by 2005 90% of drivers already used winter tires. So there wasn't that much brand new rubber on the road after all. If the same factor held true in Ontario where only 50% of drivers use winter tires, would we get a 25% drop in fatalities? How much is that worth?
3. Because a low probability event like a car accident (yes, on average it doesn't happen THAT often) DOESN'T happen to you while driving with all-seasons for 25 years, doesn't mean that it was a safe choice. This is not so much about your life, but about others' lives that might be affected because you didn't notice that black ice, or because that kid ran into the street in front of you. It's like saying we should do away with child-seat laws because when I grew up my dad drove with me on his lap and hey I'm still alive!
4. Who can argue with the need to improve the overall skill of drivers? (Ok, some can and will argue I'm sure. What, mandatory driver training?? What right does the government have to tell me how to drive?) I am here to break the news to you: discussion forums like this around the world are filled with posters claiming that drivers in THEIR region are the worst. Hey, it ain't a competition! But seriously, to somehow attribute the cause of accidents to immigration is just plain wrong-headed and likely prejudiced. Please see your anger management specialist.

(For those who hate clicking on links, accident rates among new Canadians is half that of "experienced" Canadians.)
5. Ironically perhaps, all-season tires were invented in the first place as a result of lobbying: of the car manufacturers who wanted one factory-installed tire to sell on any vehicle at any time of year.
As a business mentor once told me though, try to make sure that facts and metrics never get in the way of a really good story
Last thing you have to ask yourself: how many bad drivers believe that THEY are, THEMSELVES, bad drivers? I know I am not one of those.
To argue that you've driven years on all seasons without an incident and dismiss the benefits of snow or ice tires is too funny. Winter or ice tires do perfom better for the conditions they are designed.
To argue they are a money grab or additional cost, it's silly too. You are extending the life of the original equipment tires so, you don't have to replace the original equipement as often.
Making it mandatory to have them in Ontario? Now that is arguable and I think the enforcement will be as stringent as the littering laws we have. The law exists but, the enforcement doesn't.
I owned a beat up VW Rabbit that I could thread a needle with it on the road with all seasons. I also had an older Mustang that even with mighty Blizzaks wasn't the greatest in the winter. So, the vehicle driving characteristics and the driver themselves can make more of an impact than the tires themselves.
I do laugh at all the AWD SUVs that require a winch or tow because their ability to get moving inspires false confidence in their ability to manuvre or stop.
I also endorse and support the benefits of winter/ice tires. They simply perform better and when you drive 60k/year in all weather conditions, I'll take every advantage I can get. Someone that drives a few thousand a year and only goes from home to the grocery store? Maybe they can wait out the conditions and drive for their milk and bread when road conditions are better.
