I'd like to revisit the issue of a unique identifier.
Other models exist. On other committees, we've talked about the popular Estonian model, I believe. It's a system that's in line with our discussions on open banking. All the information is centralized and people can access it using a unique identification number.
At the end of the day, no matter what you call it, a social insurance number is a unique identification number, so it's important to understand the system's limitations. It's all well and good to have the ultimate ultra-modern system, but if a single unique identifier is assigned to an individual, the information will always be vulnerable if someone gets a hold of it.
