A place on a list. Registration is an administrative status. It is not a booking, and it is not proof that any service has started.
London families use the same province-wide Ontario Autism Program as everyone else in Ontario. The 22.5% with active core funding agreements is an administrative status that does not establish service receipt.

Not published. Ontario publishes no comparable city-level wait or prevalence figure for London. The figures above are provincial, and this page does not estimate a local one.
OAP-registered providers deliver core clinical services once a funding agreement is in place. Private providers are also available to families who cannot wait, at their own cost.
A listing here is not an endorsement, a ranking, or proof of current availability. Confirm intake directly with each organization.

A diagnosis opens the funding route. School support runs on its own track and does not wait for it.
A formal diagnosis is the first step to registering for OAP funding. These are the hubs listed for London families; private assessment is also available.

Two systems, two clocks. School supports are decided by the board, not by AccessOAP.
Families navigating autism services in Ontario face a documented multi-year wait. Here is the Ontario data — and a two-minute way to push back, when you are ready.

Ontario does not publish a comparable city-level or province-wide average OAP wait. Registration and active funding agreements are administrative statuses and are not proof of service receipt. Contact AccessOAP and local providers for current status and intake timelines.
Thames Valley Children's Centre (TVCC) and Children's Hospital at London Health Sciences Centre (LHSC) are the primary public diagnostic hubs in London. Private assessments are also available through several local psychology practices — contact providers directly for current pricing and wait times.
Thames Valley Children's Centre (TVCC) is the largest OAP-approved provider in southwestern Ontario, offering diagnosis, ABA therapy, speech-language pathology, and occupational therapy. TVCC serves London, Middlesex, Elgin, and Oxford counties. Families register through AccessOAP to access TVCC services under OAP core clinical funding.
Thames Valley District School Board (TVDSB) uses the provincial IEP process. Request an in-school team meeting to initiate an assessment. IPRC determinations can designate exceptional pupils eligible for special education placement. TVDSB offers ASD classes at select schools and integrated support at most others.
