A news report on this matter says:
According to sources, the crisis prompted the CRA to contact the office of Revenue Minister Marie-Claude Bibeau.
The agency prepared media lines to respond to inquiries should there be questions about the breach of H&R Block data and why the agency paid out millions to scammers.
In the end, the public was never alerted to the scheme.
The scenario that you described, sir, was to help contain the threat, perhaps, take action and inform your office immediately, before then informing Canadians. This looks like a government not protecting Canadians but protecting itself from the criticism of Canadians who were the victims of, potentially, the government's negligence—likely the government's negligence, in fact.
Do you believe it's acceptable for the minister to have withheld this information from Canadians?
