On the eve of the Winter Olympics, over 300 CEOs and senior executives of Canadian businesses met in Vancouver to accelerate the implementation of sustainable business practices. The highly interactive day not only gave the executives an opportunity to explore new opportunities for collaboration, but may yet prove to have been a green business tipping point in Canada. David Cheesewright, Walmart Canada’s CEO and the host of the event, kicked off the day by challenging the delegates to use the summit as a vehicle to "build a bigger team" – to share lessons learned and best practices that will benefit all businesses, large and small. He encouraged the delegates to create stretch goals and foster experimentation in their organizations, with the understanding that the road to sustainability is full of unknowns.
