Practice Tips & Regulatory Notices are available to any interested party to promote better understanding of the services architects offer and to generally help clarify the expectations of those who work with architects.

In 2009 Practice Bulletins were reviewed for accuracy, currency of content, elimination of redundancies and consolidation where appropriate. The bulletins have been re-organized and reformatted from the previous A, B, C, D and Numeric versions into Practice Tips and Regulatory Notices, ‘PT’ and ‘R’ series.

The one exception is Practice Bulletin A.9 Ontario Building Code (OBC) - OBC Data on Drawings, containing Data Matrixes Part 3 and 9, and Part 11, which is being maintained as it is currently listed in Regulation 27.

(Practice Tip PT.3 2006 Building Code (BC) - BC Data on Drawings contains the same information.)
