I'm not sure if this helps, but you might want to read this article
. The smoking regulations also might need to be taken into account, in addition to the liquor laws.
The Nova Scotia Liquor Control Act
18A (1) The Board may permit an underage entertainer to enter and remain in a tavern, beverage room, lounge or cabaret solely for the purpose of presenting a live performance of a musical nature by the underage entertainer.
(2) A written request, in such form as the Board may require, shall be filed with the Board by the licensee in order for consideration to be given for an underage entertainer to perform in premises in respect of which a tavern license, beverage room license, lounge license or cabaret license has been issued and is in effect.
(3) Written consent, in such form as the Board may require, shall be filed by the parent or legal guardian of the underage entertainer in order for the Board to consider a request made pursuant to these regulations.
(4) An underage entertainer shall be permitted to be on licensed premises only for the duration of the performance and shall not remain in the patron accommodation area while not performing.
(5) While in the licensed premises, the underage entertainer must be accompanied by a parent, legal guardian, or person over the age of nineteen years who has been designated in writing by the parent or legal guardian as responsible for the underage entertainer for the duration of the performance in the licensed premises.
(6) The licensee shall ensure that at no time are alcoholic beverages served to or consumed by the underage entertainer.
(7) Performances which are included under these regulations are live vocal, instrumental or dance presentations. Permission for underage entertainment pursuant to these regulations will only be given where it can be demonstrated that
(a) the performance will foster the musical development of the underage individual; and
(b) the performance will serve to promote the growth and development of music and culture in Nova Scotia.
So it looks like the following need to happen, in this order:
1) Your parents need to provide written consent to the venue for you to perform there.
2) The venue has to apply for permission from the Liquor Board.
3) You need to be accompanied by a parent or someone over the age of 19 who has been designated in writing by your parents as being responsible for you.
4) You are only allowed on premises for the duration of the performance, and you cannot be in the licensed area when not performing.
Sounds simple enough, but you need to get moving on it ASAP so the venue can follow the correct procedure with the Liquor Board.
BTW, i found this information easily by going to http://www.gov.ns.ca
and searching for "underage".
