Direct answer
To challenge an OAP invitation decision, contact MCCSS directly at 1-833-425-2445 and request a formal review in writing. If the dispute involves an accommodation request that was denied, file a formal complaint through ServiceOntario. The Ontario Human Rights Code also provides recourse through the Human Rights Tribunal of Ontario if you believe the decision was discriminatory.
Start with the short answer, then reveal deeper context where helpful.
If you believe your OAP invitation decision — or a decision about your eligibility, funding amount, or service category — is incorrect, begin by contacting the OAP at 1-833-425-2445. Request a formal written explanation of the decision. Ask specifically what criteria were applied and which documentation was considered. Keep detailed notes of all conversations, including the date, time, and name of the representative.
If an OAP decision involved a denial of accommodation — for example, a request for expedited access based on your child's medical urgency or disability-related need — and MCCSS denied that request, you may have grounds to file an application with the Human Rights Tribunal of Ontario under the Human Rights Code, R.S.O. 1990, c. H.19.

If the MCCSS response is unsatisfactory, submit a formal complaint through ServiceOntario (ontario.ca/feedback) or through the Ontario Ombudsman if you believe the process was unfair. The Ontario Ombudsman reviews provincial government decisions for fairness, but cannot order MCCSS to change its policies — they can recommend corrective action.

The HRTO application must be filed within one year of the decision. The HRTO process is free and accessible without a lawyer, though legal support from ARCH Disability Law Centre or a community legal clinic is recommended. The Human Rights Legal Support Centre (1-866-625-5179) offers free intake consultations.
