In Canada, the minimum legal drinking age (MLDA) is 18 years in Alberta, Manitoba and Québec and 19 in the rest of the country. Given that public health organizations have not only recommended increasing the MLDA to 19 years, but also have identified 21 years as ideal, the current study tested whether drivers slightly older than the MLDA had significant and abrupt increases in alcohol-impaired driving (AID) crimes, compared with their counterparts just younger than the MLDA.

AID criminal incidents by drivers aged 15-23 years (female, n = 10 706; male, n = 44 973).
Police-reported AID incidents from the Canadian 2009-13 Uniform Crime Reporting Survey.
Significant gender × MLDA effects supported gender-specific models. Compared with males slightly younger than the MLDA, those just older had abrupt increases in AID incidents of 42.8% [95% confidence interval (CI) = 20.4-66.3%, P < 0.001], 28.1% (95% CI = 16.0-40.7%, P < 0.001) and 35.1% (95% CI = 22.4-48.4%, P < 0.001) in provinces with an MLDA of 18 years, 19 years and across the country, respectively. Among females, AID incidents increased by 39.9% (95% CI = 1.9-79.6%, P = 0.040) in provinces with an MLDA of 18 years, and by 19.4% (95% CI = 2.1-37.4%, P = 0.028) at the national level.
Release from drinking-age restrictions appears to be associated with increases in alcohol-impaired driving offenses among young drivers in Canada, ranging from 28 to 43% among males and from 19 to 40% among females.
在加拿大，艾伯塔省、马尼托巴省和魁北克省的最低法定饮酒年龄（MLDA）为 18 岁，而其他省份为 19 岁。鉴于公共卫生组织不仅建议将 MLDA 提高到 19 岁，而且还将 21 岁定为理想年龄，本研究测试了略高于 MLDA 的驾驶员与刚低于 MLDA 的驾驶员相比，是否存在酒后驾车（AID）犯罪的显著且突然的增加。

显著的性别×MLDA 效应支持性别特定的模型。与刚低于 MLDA 的男性相比，仅年长的男性 AID 事件的急剧增加了 42.8%（95%CI=20.4-66.3%，P<0.001），28.1%（95%CI=16.0-40.7%，P<0.001）和 35.1%（95%CI=22.4-48.4%，P<0.001）在 MLDA 为 18 岁、19 岁和全国范围内的省份。在女性中，在 MLDA 为 18 岁的省份中，AID 事件增加了 39.9%（95%CI=1.9-79.6%，P=0.040），在全国范围内增加了 19.4%（95%CI=2.1-37.4%，P=0.028）。
从饮酒年龄限制中释放出来似乎与加拿大年轻驾驶员酒后驾车犯罪的增加有关，男性增加 28%至 43%，女性增加 19%至 40%。
