The Ontario Building Code | Sloping Ground

4.2.4.5. Sloping Ground

(1) Where a foundation is to rest on, in or near sloping ground, this particular condition shall be provided for in the design.

In Plain Language

Where a foundation will rest on, in, or near sloping ground, that specific site condition must be accounted for in the design, since sloped ground can affect bearing capacity and stability differently than level ground.
