Early Intervention (EI)
Comprehensive developmental support for infants and toddlers (0-5) with developmental delays or disabilities, combining multiple therapy approaches in natural settings.
What Is Early Intervention?
Early intervention (EI) refers to the system of services and supports for infants, toddlers, and young children (typically birth to age 5) who have developmental delays or are at risk due to a diagnosed condition. EI aims to support development during the critical early years when the brain is most plastic.
EI programs typically include a combination of therapies (speech, OT, PT, developmental), family support, parent coaching, and connection to community resources. Services are delivered in natural environments — your home, daycare, or community settings.
In Canada, early intervention is primarily provided through provincial programs including Infant Development Programs (IDPs), children's treatment centres, and early childhood development services.
Who Benefits from Early Intervention?
autism
Early intensive intervention before age 4 shows the strongest outcomes for autism. EI focuses on social communication, play skills, and adaptive behaviour during the critical developmental window.
down syndrome
EI from birth supports all areas of development. Infant Development Programs provide in-home support for families and coordinate therapy services from the earliest days.
cerebral palsy
Early PT and OT through EI programs prevent secondary complications, support motor development, and ensure timely access to equipment and orthotics.
hearing loss
Early identification and intervention (ideally by 6 months) for hearing loss dramatically improves language outcomes. EI connects families with audiology, SLP, and deaf/hard of hearing support.
What to Expect in a Session
First Session
An intake meeting (60-90 minutes) with an early intervention consultant who reviews developmental history, conducts a screening, and develops an individualized family service plan (IFSP) with your family's priorities.
Ongoing Sessions
A consultant visits your home or daycare regularly to model developmental activities, coach you on strategies, and coordinate with other therapists. Sessions focus on embedding learning into daily routines.
Your Child's Role
Your child participates in natural play and daily activities while the consultant coaches you on how to support development within those routines.
Caregiver's Role
You are the primary interventionist. EI is family-centred — the consultant coaches and empowers you to support your child's development throughout the day, not just during sessions.
When to Start
Early Childhood (0-5)
As early as possible — ideally at birth for known conditions, or as soon as a delay is suspected. The first three years are the most critical period for brain development.
School Age (6-17)
EI transitions to school-based services at age 4-5. Ensuring a smooth transition plan is essential.
General guidance: Do not wait for a formal diagnosis to access early intervention. Most programs accept children based on developmental delay alone. Earlier is always better.

Evidence & Research
Early intervention has strong evidence across all disability populations. Research consistently shows that children who receive early, appropriate intervention have better developmental outcomes than those who start later. The economic evidence also supports EI — every dollar invested in quality early intervention saves $7-16 in later services.
Red Flags to Watch For
Be cautious of any provider who:
- The program does not involve you as a parent or prioritize your family's goals and priorities
- Services are only available in a clinic setting rather than in your child's natural environments
- There is no individualized plan — all families receive the same generic services
- The program does not coordinate with your child's other therapists and medical team
- Wait times are excessive (months to years) without interim support being offered
How to Find a Provider
- 1
Contact your local Infant Development Program (IDP) — available in every province, usually through a simple phone referral
- 2
Ask your paediatrician or family doctor for a referral to your regional children's treatment centre
- 3
Call your provincial early childhood development information line (e.g., Ontario Early Years Centres, BC Aboriginal IDP)
- 4
Contact your local public health unit — they can connect you with developmental screening and early intervention
- 5
Reach out to your provincial disability organization for help navigating the early intervention system
