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