Comparing per-km safety records is meaningless when the population of one country is ten times greater than the other. I know Turbo was referring to Ontario and not Canada at large but just wanted to point out that such statistics are intended to deceive. A country with population 1 would easily have the world's best per-km safety record, even if that single citizen had a fatal crash (100% on-road mortality rate).

For the record, I'm not for or against changing the speed limit (though I'd love to drive on faster highways).
