As British Columbia lays out plans to shed COVID-19 restrictions, the person who ensures fair access to government resources is calling for caution, especially when deciding who is eligible for relaunched services.

A statement from the office of B.C.'s ombudsperson says vaccination certification programs are being explored in B.C. and in jurisdictions across Canada.

Ombudsperson Jay Chalke says this raises concerns about provincial or local public services being limited based on vaccination status.

The organization representing the public advocates across Canada has released guidance about how so-called vaccination passports could affect receipt of services under its members' jurisdiction such as municipal, health, education and other provincial ministries.

Chalke says fairness must be at the centre of any passport program and the national guidance document created by the Canadian Council of Parliamentary Ombudsman agrees. It says passports must be open to appeal, alternative services must be available for those who have not been vaccinated and governments must offer clear legislation or policy directions about how vaccine certifications are used.
