幾多歲係 Minor child？

唔同省係會有唔同，請參考 IRCC 官網以下說明：

Who is a minor?
In Canada, each province or territory defines the age of majority. Anyone under the age of majority at the time of their arrival in Canada is considered to be a minor child.

• The age of majority is 18 in Alberta, Manitoba, Ontario, Prince Edward Island, Quebec and Saskatchewan.
• The age of majority is 19 in British Columbia, New Brunswick, Newfoundland and Labrador, Nova Scotia, the Northwest Territories, Nunavut and the Yukon.
