I did a little digging after hearing a CBC news story on pending helmet legislation. I sent this to:
The Right Honourable John Weston:
Dear Sir:
If you are seriously persuing this helmet legislation it had better be based on the statistical sciences and not on anecdotal mothers...( or others who may have 'guilt' issues )
There are many more things to worry about - like getting to Whistler on half-gone all-season tires, while talking on a cell phone.
Perhaps,more could be gained by movies in the day-lodges showing titles like "Bad physics " for snow-sports 'enthusiasts' - big,bad,sick air and landings on-top of turkeys stopped under that roller... " Hucks Gone Bad ".
My other question is " Does the honourable member ski ?" If so you will know what I am talking about when I cite and real - not imagined - objective and subjective dangers.Perhaps legislating against ear-phones and autism would be more effective at making 'us' safer.
Lastly- skiing is about getting out and maintaining total awareness - and not caving in to politically-correct and semi-autistic imaginations.

Abstract
The use of helmets has been proposed as a means of reducing the incidence of fatality in skiing and snowboarding. This paper presents results that suggest that while helmets may be effective at preventing minor injuries, they have not been shown to reduce the overall incidence of fatality in skiing and snowboarding even though as many as 40 % of the population at risk are currently using helmets. The results indicate that the use of a helmet will indeed influence the primary cause of death, but perhaps not the ultimate outcome.
( PERHAPS THIS EXCERPT WILL OFFER SOME PERSPECTIVE - NOTE THE 1992-2005 TIME-SPAN )
A TOTAL of 8019 in 7252 injured skiers and boarders were recorded. ( sounds like a lot, don't it ? )
THIS IS FOR A TOTAL OF 4.884 MILLION SKIER/BOARDER VISITS DURING THE PERIOD OF THIS STUDY - 1992-2005 - THIRTEEN YEARS.
"... resulting in an injury rate of 1.5 injured skiers/boarders per 1000 skier/boarder days. " ( These injuries INCLUDE head trauma...)
" Most injuries occurred during alpine skiing (49% ) and snowboarding ( 43 % ).Telemarking skiboarding accounted for only 4 % ...
“There is no evidence they reduce fatalities,” said Dr. Jasper Shealy, a professor from Rochester Institute of Technology who has been studying skiing and snowboarding injuries for more than 30 years. “We are up to 40 percent usage but there has been no change in fatalities in a 10-year period.”[6][7] There is evidence that helmeted skiers tend to go faster.[8)
( This next bit was from a web-site that wants to sell helmets:)
http://www.jasminalpine.co.uk/ski_helmets_id16.html" Each year, between 12,000 and 16,000 skiers and boarders leave the slopes with head injuries, which account for about 14 percent of all snowsliding injuries, reports the U.S. Consumer Product Safety Commission (CPSC).|
( Where did they get that 'statistic '- perhaps some of the mothers saw it... I will track this one down...if it exists )

Jasper Shealy is Professor Emeritus, Rochester Institute of Technology, Rochester NY. This article includes material from Robert Wilson, Professor, University of Vermont College of medicine, Burlington VT and Carl Ettlinger, President, Vermont Safety Research, Underhill Centre VT
EDITOR’S NOTE: Articles on ski helmets, especially in the mainstream media, regularly use first-person anecdotes, lift-line opinions and arguments about mandatory helmet laws to discuss the subject. You’ll find none of this in the following report which was first presented at the International Symposium on Ski Trauma and Skiing Safety in Avemore, Scotland in May 2007 and published in the Journal of ASTM International. Jasper Shealy et al simply stick to the facts to explain what we can, and can’t, expect from our helmets. Although the data collected for the paper is from south of the border, the authors see little reason to believe results would vary significantly if Canadian skiers and snowboarders were included in the study.
( here IS ANOTHER IMPORTANT POINT: SKI HELMETS DO NOT PROTECT AT 'NORMAL' SKIER SPEEDS - OFTEN 40 TO 60 KPH)
For example, for the ASTM F2040 Recreational Snow Sports helmet standard, the impact on a flat steel anvil is at 22.3 kph, and the impact on an edge anvil is at 16.2 kph. Under each of those circumstances, the peak straight-line acceleration on impact cannot exceed 300 g as registered by an accelerometer embedded in the head-form. Rotational acceleration is not measured or considered.
Keeping in mind the above figures, most snowsports fatalities due to head impact with solid fixed objects such as a tree take place at speeds of 44 kph or more. That speed is the average maximum speed seen by 650 consecutive skiers and snowboarders at three different resorts on wide, groomed blue-square trails—the sort of trails where most fatalities occur. Skilled young adult male skiers and snowboarders tend to go even faster than the rest of the population. This group is also the most commonly fatally injured. A review of most fatality reports shows that the typical fatality occurs to an experienced male between late-teens and late-30s in age, while travelling at a relatively high speed on the margins of intermediate runs.
I hope you will consider these points and perhaps find Shealy's original book or paper.
I have been ski-bumming for over 25 full-time seasons and every year the sport seems to get a little more dummed down. As does our society. I hope I have spent this brief time on this helmet point well - and that I am talking to an adult who owes more to his considered objective opinion than his more pressing societal constructs.
