The Pandora Papers, revealed last week, aren't the first big leak of records to expose secret bank accounts and wealth hidden offshore. Such files have found their way into the hands of journalists and governments repeatedly in recent years.

The Pandora Papers, a huge cache of data containing secret details of offshore bank accounts and shell companies, is thought to be the largest ever leak of tax-haven financial information. The files, stemming from 14 offshore-services firms, were leaked to the International Consortium of Investigative Journalists, which shared them with its partner media outlets (including CBC/Radio-Canada) and began publishing stories on Oct. 3. 

But the Pandora Papers isn't the first such leak. Confidential lists of offshore account-holders have found their way into the hands of journalists and governments a number of times over the last decade and a half. Here are five important previous leaks of records from various tax havens:

Paradise Papers - 2017

What: Records from several dozen jurisdictions held by the global offshore law firm Appleby, which is headquartered in Bermuda, as well as a Singapore-based offshore services provider. The leak also included the corporate registries from 19 countries and territories.

Number of people in data: More than 120,000.

Canadians: 3,000-plus.

Records leaked: 13.4 million.

HSBC Geneva - 2009

The French government got its hands on the account list in 2009 after seizing Falciani's computer. Portions of the leak were later obtained by tax authorities around the world and, eventually, shared with journalists. A Swiss court sentenced Falciani in absentia in 2015 to five years in prison for economic espionage, but has been living in Spain since then and has not been extradited.  

Tax recouped: The CRA said in 2015 that 264 Canadians had come forward to make voluntary declarations of previously undeclared income, paying $28.4 million in tax. Revenu Québec said it recovered $34.4 million from 88 individuals who hadn't declared all their income.
