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