description: This profile defines a set of constraints to the FHIR Procedure resource for use in Ontario Patient Summaries (PS-ON).  It refines constraints applied  to the Procedure resource by the PS-CA project, which is informed by the constraints of the [Procedure-UV-IPS profile](http://hl7.org/fhir/uv/ips/StructureDefinition-Procedure-uv-ips.html) and the [Canadian Baseline Profile](http://build.fhir.org/ig/HL7-Canada/ca-baseline/branches/master/StructureDefinition-profile-procedure.html) to allow for cross-border and cross-jurisdiction sharing of History of Procedure information.
