Do Canadian insurance plans treat an ADHD assessment as a psychological service like therapy?

Some Canadian group insurance plans process an ADHD assessment under the same psychology or paramedical heading as counselling, especially when a registered psychologist invoices hourly, but that is not a national rule and it is not how every booklet is written. There is no single federal extended-health statute that defines ADHD testing as therapy. Provincial public plans are different again: OHIP in Ontario and MSP in British Columbia cover medically required physician services, not a private psychologist assessment. Private carriers decide whether an assessment is eligible, whether it shares a dollar maximum with talk therapy, and whether psychoeducational batteries are excluded as educational rather than health services. Coverage varies by province. Rules, coverage and referral pathways vary by province and can change; confirm the current position with the relevant institution or provincial program.
