description: This profile defines a set of constraints to the FHIR AllergyIntolerance resource for use in Ontario Patient Summaries (PS-ON).  It refines constraints applied to the AllergyIntollerance resource by the PS-CA project, which is informed by the constraints of the [AllergyIntolerance-UV-IPS profile](http://hl7.org/fhir/uv/ips/StructureDefinition-AllergyIntolerance-uv-ips.html) and the [Canadian Baseline Profile](http://build.fhir.org/ig/HL7-Canada/ca-baseline/branches/master/StructureDefinition-profile-allergyintolerance.html) to allow for cross-border and cross-jurisdiction sharing of Allergies and Intolerances. It documents the relevant allergies or intolerances (conditions) for a patient, describing the kind of reaction (e.g. rash, anaphylaxis,..); preferably the agents that cause it; and optionally the criticality and the certainty of the allergy.
