Direct answer
Ontario's old 14-region LHIN terminology should not be used as a current OAP waitlist breakdown: Ontario reports that the 14 HCCSS organizations were consolidated into Ontario Health atHome in June 2024. For core clinical services, Ontario says children and youth are invited in the order they registered. The reviewed primary sources do not verify the draft's regional rankings or wait-time estimates, so those claims are omitted.
Every answer on this site sits on the same verified counts. These are the current figures.
Published:
Ontario's public accounts identify the 14 Home and Community Care Support Services organizations as Local Health Integration Networks operating as HCCSS.
A later Ontario public-accounts source reports that the 14 HCCSS organizations were consolidated into a single organization, Ontario Health atHome, in June 2024. The draft's LHIN provider rankings are therefore not presented as a current regional comparison.
Ontario states that children and youth enter core clinical services in the order that they registered for the Ontario Autism Program. The reviewed source does not state that LHIN region, age, or urgency changes that invitation order.
AccessOAP says families may access eligible core clinical services through providers and agencies located across the province. Ontario also says that joining the OAP provider list is voluntary, so the directory should not be presented as a complete regional count of providers.
Ontario's published rule says children and youth are invited to core clinical services in the order they registered for the Ontario Autism Program. This review found no primary-source support for the draft's claim that LHIN region changes that order.
Yes. AccessOAP says families have the option to access eligible core clinical services through providers and agencies located across the province, and a care coordinator can help a family determine its options.
No complete regional count should be inferred from that list. Ontario states that joining the OAP provider list is voluntary for professionals.

How long do families wait for Ontario autism services?
VerifiedOntario autism wait times for core clinical services now exceed 5+ years (Ontario Autism Coalition, July 2026). Funding invitations are currently reaching families who registered in August 2021 (Ontario Autism Coalition, July 2026 (reported from community intake)). This delay far exceeds the sensitive early intervention window recommended by developmental specialists.

Is the Ontario Autism Program underfunded?
VerifiedYes. The Financial Accountability Office (FAO) determined that $1.35 billion annually is needed to serve all registered children at 2018-19 service levels. The 2026-27 Ontario Budget allocated $965 million, leaving an estimated $385M+ annual shortfall. This gap is the primary driver of the perpetual 91,974+ child waitlist.
