Built for Canadian projects
Most calculators online assume US lumber sizes, US dollars and US codes. Ours follow what you will find at a Canadian yard or building supply store: nominal and actual lumber sizes, litres and gallons, cubic yards and cubic metres, and notes on the National Building Code of Canada. Provinces adopt their own versions of the code, so your local building department always has the final say.
