OAP Wait Time Estimator

This OAP wait time estimator provides estimates only. Regional figures are site estimates derived by distributing the province-wide FOI total proportionally by census population, they are not official government per-region data.

Your actual wait time may vary significantly based on your child's specific needs, urgency level, provider availability in your area, and changes to OAP funding. The confidence interval (±30%) accounts for this variability.

For your specific wait time position, contact AccessOAP at 1-833-425-2445.

Based on our site estimates (province-wide FOI totals distributed by census population), Niagara Region and Durham Region may have shorter wait times than higher-population areas. These are modelled estimates, not official government per-region figures.

Wait times vary significantly based on service type and provider availability. The Ontario government does not publish official regional waitlist breakdowns. Always contact AccessOAP (1-833-425-2445) or local providers for current availability in your area.

Ontario publishes no province-wide average wait for OAP Core Clinical Services (intensive ABA/IBI therapy). The Ontario Autism Coalition (July 2026, reported from community intake) found invitations are currently reaching families who registered in August 2021, a wait of 5+ years for that cohort.

Foundational Family Services have shorter wait times around 24 months, while Urgent Response Services average around 18 months.

Wait times vary by region. Regional figures on this site are modelled estimates based on population-weighted distribution of the province-wide total, they are not official government per-region data.

Your OAP waitlist position is primarily determined by your registration date with AccessOAP. Earlier registration dates receive priority for services.

However, urgency needs may affect timing for some services. Your position is NOT determined by when you received your autism diagnosis, only when you officially registered with the OAP.

OAP wait times have increased from 18 months in 2019 to 60+ months (5+ years) in 2025 due to three main factors:

• Increased demand: More children are being diagnosed and registered each year
• Provider shortage: There are not enough trained BCBAs and therapists to meet demand
• Funding gap: OAP funding has not kept pace with growing demand, only $965M was budgeted for 2026-27 versus $1.35B (2020 FAO modelling)

In a 2020 modelling scenario, the FAO estimated $1.35B annually would be required to eliminate the waitlist at 2018-19 service levels.
