This is a very good thing, but seems like sort of a no-brainer. Legal drinking age in Canada varies by province, but is generally 18 or 19 years old.
"As of Sunday, (according to new legislation in Canada) drivers aged 16 to 21 will have to have a zero blood-alcohol level when they drive.
"We are trying to obviously put a safety net around our youth," said Gregg Thomson, a volunteer and director-at-large with MADD.
The current permissible blood alcohol level for drivers with full G-class licenses is 0.05 per cent. Anyone within the 0.05 to 0.08 range is considered impaired or in the "warn" range.
Thomson said the new law is broad, covering 16- to 21-year-olds, regardless of whether they held restricted or full licences."
Correct me if I'm wrong, but I think most States in the US have similar laws for people under 21?
I'm too lazy to do the research :)
