It may or it may not be.
As part of application processing, IRCC will assess what the costs of her conditions are to the medical and social services systems in Canada. So they will look at what the special education she is receiving costs the system. If they assess this amount as under $20,000 per year, then you should be fine. If over, then you can expect to receive something called a PFL (procedure fairness letter) which will indicate that IRCC plans to refuse your application and give you a chance to argue otherwise (i.e. argue and prove the costs to the system are under $20K). If you happen to get a PFL, my recommendation would be that you engage a lawyer to support you in responding.
