Indigenous Peoples and newcomers are two of the largest and fastest growing populations in Canada (Statistics Canada, 2022; Zimonjic, 2022). Yet despite this, little is known about their experiences navigating and accessing autism services for their children. To address this gap, the current study sought to explore the autism service needs and priorities of Indigenous and newcomer families in Canada. A total of 19 participants (9 Indigenous and 10 newcomer caregivers) were selected using purposive sampling to participate in a semi-structured interview. The findings revealed that Indigenous families prioritized the need for services in rural and remote areas, tailored information to their needs, and support preserving their cultural heritage. On the other hand, newcomer families emphasized the importance of peer support, quality standards for services and therapies, and support during transition periods. Similarities across both groups indicated the need for addressing the lengthy waitlists for services, which have also been reported in the general population in Canada, having services and professionals place a greater emphasis on the child’s strengths, and culturally safe services and practice. The present findings have important implications for the design and implementation of services and supports which reflect the needs and priorities of underserved communities. •Little is known about how Indigenous Peoples and newcomers navigate and access autism services for their children in Canada.•Indigenous families prioritized the need for services in rural areas, tailored information, and support preserving culture.•Newcomer families emphasized the importance of peer support, quality standards, and support during transition periods.•Similarities included addressing waitlists, services that emphasize their child's strengths, and culturally safe services.•Findings have important implications for service design which reflects the needs of underserved communities.
