This is Zuckerberg’s Class C in miniature, and it is routine Canadian private-company planning rather than anything exotic. You exchange your common shares for fixed-value preferred shares carrying the votes, and new growth common shares are issued to a family trust or to the next generation. Future appreciation accrues outside your estate; control stays with you through the voting preferreds.

Honest timing note: a freeze crystallises today’s value, and you will regret it if the business grows faster than you expected to need the freeze. For a company incorporated in April 2026, with no established valuation, this is almost certainly premature. Know the mechanic; do not execute it yet.
