PBO Jean-Denis Frechette has mused about suing the CRA to obtain access to the data.

The prime minister said the PBO and the agency have reached an agreement that will deliver the data by end of the month.

Prime Minister Justin Trudeau stated Monday the Canada Revenue Agency has struck a deal with the parliamentary budget officer to give his office the data it has to find out just how much revenue Ottawa loses every year to offshore tax havens and other tax avoidance schemes.

The PBO has been asking for the data for a private analysis for five years. Until now, the Canada Revenue Agency has refused to provide it, citing privacy concerns.

He said it will be provided in a manner that will ensure the protection of personal information.

The Conference Board of Canada has approximated that tax evasion and tax avoidance cost the federal treasury anywhere between $8.9 billion and $47.8 billion annually.
