You did the hard part. After years of suspecting, reading, and recognizing yourself in other people's stories, you asked your doctor for an assessment. Then you heard the timeline, and the timeline was long. Publicly funded adult ADHD assessments in Ontario often involve waits of many months, sometimes more than a year, and private assessments cost more than many people can spare.
You are not imagining the bottleneck. A study from researchers at ICES, North York General, and SickKids, published in JAMA Network Open in late 2025, found that new stimulant prescriptions in Ontario rose 157 percent between 2015 and 2023, with the steepest growth among women aged 25 to 44. Recognition of adult ADHD, especially in women, has surged, and the assessment system has not kept pace.
Here is the thing the waitlist letter does not tell you: a great deal of what is making life hard right now can be worked on before any diagnosis arrives.
A waitlist can hold your assessment. It does not have to hold your life.
What Is Happening With ADHD Assessments in Ontario
Demand has outgrown capacity. Awareness of how ADHD presents in adults, and especially how it has been missed in women for decades, has expanded who seeks assessment; the signs that get missed are covered in detail here. Family doctors vary in their comfort diagnosing it, psychiatrist referrals stack up, and the result is the wait you are now sitting in.
A wait like that does real damage beyond inconvenience. It leaves people suspended in a strange in-between: too aware of the pattern to unsee it, not yet permitted to name it.
What I Can and Cannot Do
Honesty first, because you deserve a straight answer before anything else. A Registered Psychotherapist cannot diagnose ADHD, and cannot prescribe medication. The assessment you are waiting for is the route to both, and nothing in therapy replaces it.
What an RP can do is treat what is actually in front of us: the anxiety, the shame spiral, the emotional flooding, the relationship strain, the exhausted self-concept built from thirty years of being told to just try harder. None of those require a confirmed diagnosis to be real, and none of them require one to be worked on.
The Struggles Do Not Need a Diagnosis to Be Treated
Consider what is likely making daily life hard right now. Emotional regulation: the zero-to-overwhelmed pipeline, the flooding during conflict. The shame story: decades of "lazy," "careless," and "so much potential" calcified into an identity, which therapy can begin dismantling regardless of what the assessment eventually says. Rejection sensitivity: the disproportionate pain of perceived criticism that wrecks relationships and has its own article here. And the anxiety and low mood that so often travel alongside attention struggles, which are fully treatable conditions in their own right, starting now.
There is also untangling to do, and it helps the eventual assessment. Poor sleep, chronic anxiety, trauma, and burnout can all mimic or magnify attention problems. Therapy that clarifies which threads are which gives you relief now and gives your assessor a cleaner picture later.
Using the Wait Well
Three concrete uses for the months ahead. First, document: keep a plain log of when attention struggles show up, what they cost, and how long they have been there. Second, gather history: old report cards and a parent's or sibling's memories are gold, because assessors look for a lifelong pattern, not a recent one. Third, bring the story into order: assessment appointments are short, and people routinely freeze and forget half of what they meant to say. Part of our work can be organizing your history so the hour counts.
If the wait is wearing on you, you do not have to white-knuckle it alone. I offer a free 15-minute virtual consultation, no forms, no commitment, just a conversation about what support during this stretch could look like. If it feels right, we go from there.
If the Answer Turns Out to Be Not ADHD
This outcome worries people more than they usually say out loud, so let it be said plainly: if the assessment concludes something other than ADHD, nothing about your experience becomes less real. The distraction, the overwhelm, the shame, the cost: all of it happened, all of it counts, and all of it remains workable. The treatment targets do not vanish with the label; sometimes the assessment simply points the work in a more precise direction.

Frequently Asked Questions
Can a psychotherapist diagnose ADHD in Ontario?
No. Diagnosis requires a physician, nurse practitioner, psychiatrist, or psychologist, and that is exactly what your assessment referral is for. What a Registered Psychotherapist can do is work with what is present now: emotional regulation, anxiety, shame, and the daily costs that do not wait for paperwork.
What should I do while waiting for an ADHD assessment?
Three things help. Document when and where attention struggles show up. Gather history, including old report cards and family memories, since assessors look for a lifelong pattern. And consider therapy for the parts of the struggle that can be worked on right now, no diagnosis required.
Will starting therapy interfere with my ADHD assessment?
No. If anything, it sharpens the picture. Untangling sleep, anxiety, and burnout from attention problems gives your assessor cleaner information, and an organized symptom history makes a short assessment appointment count.
