In connection with the changes described in "Introducing income tax folios" and "Cancellation of income tax technical publications", changes have been made to the income tax technical publications retained on the Canada Revenue Agency website.

Interpretation bulletins are gradually being replaced by a new technical publication product called the income tax folios, which will also incorporate the information currently contained in the income tax technical news (ITTNs). The update process is expected to take place over a number of years.

As the updated information is published, any related interpretation bulletins and ITTNs will be cancelled.

ITTNs that have been replaced by income tax folios are identified in the ITTN – income tax folio table of concordance. IT bulletins that have been replaced by an income tax folio are identified in the Interpretation bulletin - income tax folio table of concordance.

As part of an initiative to remove outdated and redundant information from the CRA website, all previously archived ITTNs were removed from the website on September 30, 2012. The affected ITTNs were ITTN #1 to ITTN #21, as well as ITTN #31R1.
