The OAA’s OBC Data Matrices are living documents that change over time in response to changes in the Ontario Building Code and to changes in practice. Revisions to the Part 3 Data Matrix have been uploaded for both the Word and the spreadsheet versions. The matrices are available as attachments to Practice Tip PT.03.

The latest update corrected the locking of some cells in part 3.15, as well as updated the seismic supplement and notes in the Site Plan Approval (SPA) matrix.

For the complete list of Practice Tips available on the OAA Website, refer to the PT. 00 Index to Practice Tips located in Practice Advisory Knowledge Base.

Practice Tips provide guidance on issues affecting the daily practice of architecture. They support members by helping them apply ‘best practices’ to meet the standards of the profession. Practice Tips are available to any interested party to promote better understanding of the services architects and other members of the OAA offer and to generally help clarify the expectations of those who work with architects.
