Toronto airport heist ranked 6th biggest gold robbery in history. I would argue Trudope is the biggest thief when it comes to canadian gold as he sold off our reserves at the beginning of his leadership.
From the article : "The gold has likely all been melted down, reforged into other forms, and made its way into local or international markets."
