How old do you have to be in Ontario Canada to get your belly button pierced without parental consent?

Informed consent applies, however each municipality can set an age limit if they choose. Generally in Canada you need to be 19 years old to get any piercing other than ear lobes done, (16 years old for earlobes). This is in keeping with the Federal government Guildlines for Body Piercing and Tattooing recommendations published by Health Canada for Personal Service Establishments (PSE's). The best bet is to call your local piercing studio and ask what age limit they have, again the city or municipality can lower or raise the age limit depending on complaints and shop history.
