Gifting public securities to a registered Canadian charity eliminates the capital gain on the donated shares. Gifting shares of a private corporation does not get that treatment, and the non-qualifying-security rules can defer the donation receipt for years. The donor-advised-fund-plus-retained-proxy structure in the Anthropic table needs liquid, publicly-marked stock to work. Yours is neither.

Saying so plainly is more useful than inventing a Canadian equivalent: this mechanic is a public-company mechanic and it stops at your door.
