The Financial Post reports in its Saturday edition that Canada's mining industry let out a collective groan after the $2.15-billion sale earlier this week of Osisko Mining, which owns one of the largest, highest-grade undeveloped gold deposits in the world. The Post's Gabriel Friedman writes that Osisko's John Burzynski could not complain about the outcome; everyone who invested made money. But two decades ago he wanted to build a new Canadian mining giant. Instead, the Windfall gold deposit he discovered in Quebec was swallowed up by South Africa's Gold Fields before it even started producing. It is a common refrain in the Canadian mining industry, which is still processing the hangover from a wave of consolidation and acquisitions roughly two decades ago that wiped out many of the country's largest mining companies. Now, some of Canada's richest mines are managed by executives working for foreign-owned companies with headquarters in Switzerland, Brazil and Australia. Although that tied into a wave of globalization that affected every industry in most countries, Canada's mining sector has long viewed Toronto -- and to a lesser extent, Vancouver -- as a global mining hub and still aspires for it to play that role.
