About Us

About Us


To identify and develop a network of Rapid Access IUC Centres of Excellence across Canada for quality care, collaboration and improved access to intrauterine contraception (IUC).


RAICE is a service that grew out of a need identified by the CNIC, or the Canadian Network for Intrauterine Contraception. Established in 2015, the CNIC consists of 8 Canadian experts in IUC who are committed to helping people access their optimal contraception method so that they can define and meet their reproductive goals.


The RAICE project was initiated and developed by Canadian Network for Intra-uterine Contraception (CNIC), which is an expert working group of health care professionals active in the field of intrauterine contraception. The clinics listed on this website are self-identified as Centres of Excellence. While the criteria are developed by CNIC, the clinics independently certify that these criteria are met. The RAICE project was supported by Bayer Inc. through the provision of an unrestricted educational grant to the University of Victoria. Bayer Inc. is not responsible for any content and associated materials or products developed by RAICE or by CNIC.
