A large portion of Rideau Street in downtown Ottawa, Ontario is seen caved in, causing a massive sinkhole that knocked out power to the majority of the downtown area on June 8, 2016. The massive sinkhole formed next to a shopping mall in downtown Ottawa, caused a gas leak and forced the evacuation of all nearby businesses. / AFP / (Chris Roussakis/AFP) / Chris Roussakis (Photo credit should read CHRIS ROUSSAKIS/AFP via Getty Images)
