At the Ceremony, each of the Finalists will have the opportunity to select a key.

The event moderator will draw finalist names at random to determine Key selection order.

The event moderator will attempt to open the Vault with the Finalists’ Keys in order, until one of the keys unlocks the Vault.

The Finalist whose Key opens the Vault will be deemed the potential winner of a cheque or direct deposit for the Grand Prize of CDN $100,000.00.
