Bank Vault
David scouts out the bank vault during the day and jumps back in at night to rob the place.
Formally known as the Dominion Bank Building, the original 12-storey building at the base of the hotel was constructed in 1914 as the headquarters for the bank and housed the largest vault in Toronto at the time. The bank branch finally closed down in 2000, and after several years of renovation featuring the addition of a 51-storey condo hotel with a 2-storey penthouse.
