Mark Wiseman talks about the importance for acting now to get to 100 million Canadians by 2100. “If you look at Canada’s demographics today, we will grow – on current trend – to about 50 million people from 37 million today by about 2050, and then we stop growing,” Wiseman – the former CEO of the Canada Pension Plan Investment Board and current global head of active equities at BlackRock – told BNN Bloomberg in an interview recorded on Thursday. “This is a trend that we have to get on top of now. If we stop growing we will have a smaller economy. If we stop growing, we’ll be less important in the world, as the rest of the world grows around us.”
