The $50K Cash Vault Contest is designed for residents of Ontario, Manitoba, Alberta, and British Columbia, requiring participants to be of age of majority in their respective provinces. The contest is governed by Canadian law, emphasizing that no purchase is necessary to enter, and the contest rules must be accepted as a condition of entry. Exclusions include employees of participating radio stations and their family members, ensuring that the contest remains fair and accessible to the general public. The contest's structure aims to engage listeners and potentially increase audience participation for the involved radio stations by offering a significant cash prize as an incentive.
