The car sharing service Uber has come under criticism for cranking up prices during Monday’s Toronto subway closure. Commuters found fares hiked by as much as five times the normal price, making the minimum fare as much as $75.00.  Uber refers to the practice as “surge pricing” and says it’s a way to encourage more drivers to hit the streets during times of unusually high demand.   An Uber spokesperson says the surge price was capped at 3 times the usual fare yesterday, although in some areas, the surge amounted to about 1.5 times the normal cost.  The company jacked fares during the December hostage crisis in Sydney, Australia, when thousands of people were trying to flee the city’s central business district.
