From a CRA press release issued two days ago on the Panama papers:
The Canada Revenue Agency (CRA) is committed to combating the abusive use of offshore jurisdictions and protecting the integrity of the Canadian tax system.
The CRA continues to pursue audits related to offshore tax evasion including some Canadian clients associated with law firm Mossack Fonseca.
The Agency is actively pursuing the cooperation of its tax treaty partners and the International Consortium of Investigative Journalists to obtain all of the leaked records that pertain to Canadian residents.
