Onsite hard-drive destruction earns its premium when a data classification, a customer contract, or an internal policy requires that drives never leave your building intact, and it usually does not earn it for routine refreshes of standard office hardware.
A mid-market company retiring its own laptops and servers almost never carries an obligation under Ontario's Electrical and Electronic Equipment Regulation, and nothing in that regulation requires it to hire an RPRA-registered provider.
A mid-market ITAD engagement should produce seven linked records: a serialized inventory of every asset collected, chain-of-custody documentation for each handoff, a certificate of data destruction or sanitization that names individual serial numbers, an exception report covering any device that failed sanitization or never arrived, a certificate of recycling showing material weights and downstream disposition, a settlement statement for resold assets, and a final disposition report that reconciles back to the submitted inventory.
NAID AAA covers onsite hard-drive destruction only when the provider holds the mobile/onsite endorsement for hard drives at the location doing the work.
