• CodeNews Issue 210 ‐ The New 2012 Building Code

• Ontario has released a new Building Code./• On November 2, 2012, Ontario Regulation 332/12 was filed 

to introduce the new  Building Code.• Most of the new Building Code will come into force on Jan 1Most of the new Building Code will come into force on Jan. 1, 

2014. However, certain requirements will come into force later on Jan. 1, 2015 and Jan. 1, 2017.Th B ildi C d b t ti ll i• The new Building Code substantially improves energy‐efficiency requirements and makes Ontario one of the leading jurisdictions in North America for water conservation.

• Ontario Regulation 332/12 is available on Service Ontario’s e‐Laws website.
