Wonga.ca is a subsidiary of Wonga.com, which is a large multinational online payday lending company based out of the UK. They operated in Canada from 2012 to 2016, but have since closed.
Their loans range from $100 to $500. Unlike most payday lenders, their rates scale based on how long you wish to borrow. For a 1 day loan you can pay 1%, and the rate scales up to 21% for 30 days.
In May 2012, Wonga was given a warning from the Office of Fair Trading about their debt collection practices. Wonga has rebutted their criticism and says that procedures have been implemented to prevent any further abuses.
