The objective of this analysis was to provide a model for the planning and costing of IYS throughout Canada over a 15-year period.</p><p><strong>Methods: </strong>To estimate resource allocation for IYS, we determined the number of hubs and hub staffing requirements by service level and jurisdiction, backbone support and infrastructure requirements by jurisdiction. A needs-based analytic framework for planning was employed to estimate the number of hubs required. The optimal mix of hub staffing requirements was determined based on prior literature. The costs of running each hub were estimated using publicly available data and internal documents from existing IYS agencies. Finally, the cost of setting up IYS hubs, IYS virtual care and respective backbone support throughout Canada was estimated and projected over 15 years and the cost-savings of IYS were calculated.</p><p><strong>Results: </strong>At maturity, it was estimated that 399 hubs-188 small, 43 medium, 168 large-across Canada would be required to address youth mental health and substance use needs. The cost of implementing IYS initiatives across Canada would vary between $4,349,126 (for less populous jurisdictions) and $248,950,524 (for more populous jurisdictions), for a total annual cost of $676,633,388 (excluding costs of infrastructure). It was estimated that the implementation of IYS hubs would lead to cost-savings of $2.1 billion annually and have the potential to be cost-effective.</p><p><strong>Conclusion: </strong>The implementation of IYS hubs can provide good value for money, in the form of high client satisfaction, earlier supports with improved youth outcomes and decreased health care costs.
