Edit: Whoops...it's my first post and I meant to reply to the questions about statutory rape in Canada.
From the Canadian Department of Justice website:
The age of consent for sexual activity is 16 years. It was raised from 14 years on May 1, 2008 by the Tackling Violent Crime Act.
However, the age of consent is 18 years where the sexual activity "exploits" the young person -- when it involves prostitution, *advertiser censored* or occurs in a relationship of authority, trust or dependency (e.g., with a teacher, coach or babysitter). Sexual activity can also be considered exploitative based on the nature and circumstances of the relationship, e.g., the young person's age, the age difference between the young person and their partner, how the relationship developed (quickly, secretly, or over the Internet) and how the partner may have controlled or influenced the young person.
The Criminal Code provides "close in age" or "peer group" exceptions.
For example, a 14 or 15 year old can consent to sexual activity with a partner as long as the partner is less than five years older and there is no relationship of trust, authority or dependency or any other exploitation of the young person. This means that if the partner is 5 years or older than the 14 or 15 year old, any sexual activity will be considered a criminal offence unless it occurs after they are married to each other (in accordance with the "solemnization" of marriage requirements that are established in each province and territory, governing how and when a marriage can be performed, including the minimum age at which someone may marry).
There is also a "close-in-age" exception for 12 and 13 year olds: a 12 or 13 year old can consent to sexual activity with another young person who is less than two years older and with whom there is no relationship of trust, authority or dependency or other exploitation of the young person.
