Although there is no specific law mandating an age a person must be to get a tattoo, some provinces in Canada have their own mandates. Many still leave the decision up to the parents.
Some tattoo artists do not tattoo anyone under the age of 18 because they believe the backlash from parents is not worth the risk. Other artists require that anyone under the age of 16 bring their parents with them to sign consent forms, and they will tattoo anyone who is 17 years old without parental consent. There is discussion on implementing a more sweeping legislation, but as of yet there is no official legislation.
