description: This profile represents the constraints applied to the MedicationRequest resource by the CA Core+ project to represent the minimum expectations for the MedicationRequest resource when used to promote capacity building for functionality found across Canadian FHIR implementations. It is informed by the constraints of shared across CIHI pCHDCF data sets and has also undergone analysis to assert alignment with the [Canadian Baseline MedicationRequest Profile](http://build.fhir.org/ig/HL7-Canada/ca-baseline/branches/master/StructureDefinition-profile-medicationrequest.html)
