Read article twice. Agree that fmr Cdn PM Harper is a dumpster fire.
About this article, I can’t figure out if the general problem is that long-form census’ are bad or good or it’s just that they shouldn’t keep it for 10 years, or that it’s being stored online.
I use old census forms for geneology and I can’t imagine not having this old data for family information. The US releases historic census data after 72 years; it’s 92 in Canada, 100 in UK (and effectively 99 in Australia, but they destroy all data anyway either through dereliction or direct policy).
Just store this stuff securely offline, off-network, local secure access only. End of story.
