Do minors need to provide authorization signed by their parents to enter Canada alone with Hong Kong passports?

No matter what passport, minors need a power of attorney to enter Canada alone.

It is suggested that parents who take 18-year-old minors to travel should bring documents that can prove the parent-child relationship. Immigrants from Macao and Shenzhen advise parents who are separated or divorced to prepare laws or other relevant documents to clarify custody. It is strongly recommended that solo travelers of any nationality, or children traveling with adults without legal custody, bring a consent signed by legal guardians or parents with legal custody, which should include:

1. Authorize him to travel and go abroad (with another person where applicable);

2. The purpose and duration of stay in Canada;

3. The detailed address and telephone number of the signatory.
