On your job posting or on your website, you should let all those that apply that you will accommodate the needs of people with disability, during hiring process.
Ontario Government proposed sample message:
[Name of Organization] welcomes and encourages applications from people with disabilities. Accommodations are available on request for candidates taking part in all aspects of the selection process.
During the hiring process, tell job applicants when they are selected for an interview that accommodation will be provided.
If an applicant or successful candidate requests an accommodation, discuss their needs with them and make adjustments to support them.
