| description | Looks up and interprets Ontario Provincial Standard Drawings (OPSD), Ontario Provincial Standard Specifications (OPSS), CSA standards, and MTO design guidelines for municipal infrastructure. This skill should be used when a design question, standard reference, or material selection needs authoritative Ontario infrastructure standards. |

Infrastructure Standards
Purpose
Retrieve and interpret the correct Ontario and Canadian infrastructure design standards for a given question, asset type, or design scenario. Provide the authoritative standard reference, key requirements, and applicable design parameters. Do not perform the engineering design — provide the standard requirements that a designer needs.
Keep this skill narrow:
- Identify the applicable standard (OPSD, OPSS, CSA, MTO manual)
- Extract the relevant requirements and parameters
- Note exceptions, recent amendments, and jurisdiction-specific overrides
- Provide the standard reference for traceability
Use when
- A design question requires an Ontario infrastructure standard lookup
- Material selection needs OPSD/OPSS guidance
- Drainage design needs MTO manual parameters
- Bridge design needs CSA S6 requirements
- A condition assessment references a standard that needs interpretation
Do not use when
- The task is to assess existing asset condition (use
infrastructure-assessment)
- The task is to produce a final engineering design (outside scope — requires P.Eng.)
- The task is a planning or zoning question (use planning skills)
