The Dock has been around since 2015. It’s an invite-only conference where tech, business and political leaders gather to talk. This year it was at a billionaire real estate magnate’s cottage estate in Ontario’s Muskoka region. And Prime Minister Mark Carney attended for part of the three-day conference.Guests are asked not to talk about what happens there, but business reporters Tim Kiladze and Sean Silcoff managed to report details about who goes, what ideas get suggested to the government and a dramatic moment involving Shopify CEO and co-founder Tobi Lütke.
