In this special capstone episode of SPARK: Conversations, host Dr. Katharine Smart speaks with Emily Gruenwoldt, President and CEO of Children’s Healthcare Canada, to reflect on two years of exploring what it means to right-size children’s healthcare systems in Canada. They look back on key themes from the series — from timely access to care, community-based services, equity, partnerships, and family-centred care to workforce and data challenges — and connect these insights to the broader work ahead. Emily shares how these conversations are shaping Children’s Healthcare Canada’s strategic priorities, including advancing a National Children’s Healthcare Strategy and evidence-informed policy solutions that can improve health and wellbeing for children, youth and families across the country. This episode marks both a closing chapter of the right-sizing series and a beginning of new opportunities to inform systems change.
