In the future, it is likely that this implementation guide will support many types of Task for different use cases. This profile is based on the CA:eReC Task, and is therefore limited to that specific use case. In future additional Task profiles will be added for other use cases." /> <jurisdiction> <coding> <system value="urn:iso:std:iso:3166" /> <code value="CA" /> </coding> </jurisdiction> <copyright value="Copyright © 2025+ Canada Health Infoway.
