This is from Ontario building code division B part 9:
________________________________________________________________________________________________________________________
Section 9.15. Footings and Foundations
9.15.1. Application
9.15.1.1. General (See Appendix A and A-9.4.4.6.)
....
(3) Where a foundation is erected on filled ground, peat or sensitive clay, the footing sizes shall be designed in
conformance with Section 4.2.

__________________________________________________________________________________________________________________________

9.15.3.2. Support of Footings
(1) Footings shall rest on undisturbed soil, rock or compacted granular fill.
(2) Granular fill shall not contain pyritic material in a concentration that would adversely affect its stability or the
performance of assemblies separating dissimilar environments.
9.15.3.3. Application of Footing Width and Area R

__________________________________________________________________________________________________________________________

Is "granular fill" in 9.15.3.2.(1) considered "filled ground" in 9.15.1.1.(3)?
 
Correct. Any foundations on disturbed soils would require a geotechnical engineer to review and approve the soils in accordance with Part 4.
