Mr Dagg asked Library and Archives Canada (LAC) for files from Project Anecdote - an investigation into money laundering and public corruption that was launched in 1993, reports CBC News.
The department initially told him that they would require 292,000 days or 800 years to furnish the documents he required. However, they realised their error later and told the 70-year-old Mr Dagg that his documents would be ready in just 80 years.
"I may get those records in my next lifetime," said Mr Dagg in an interview to CBC News.
According to the Access to Information Act, any Canadian can request government information for a $5 fee.
"This then determines how long it will take to process the request."
