33 years of partnership in the Canadian medico-legal market.

REI was built around a simple idea: that the lawyers and adjusters working complex files deserve a partner who actually picks up the phone — and one whose assessors show up, wherever in Canada the file needs them.

OUR VISION

To become the trusted partner for medical assessments across Canada where process, discipline, accountability and defensibility are never left to chance.

OUR STORY

How REI began and what we believe.

For more than three decades we have supported organizations navigating complex medico legal decisions. Founded on principles of independence and clinical integrity, our organization was built to provide objective evaluation where clarity is essential. Overtime we have grown into a national provider while maintaining the personalized service of a boutique practice. Our longevity reflects consistent performance, trusted relationships and disciplined professional standards.

Experience is not simply time in operation - it is the refinement of process, judgement and expertise build case by case over many years. When decisions carry financial legal and human impact clarity matters we deliver medical opinion you can rely on. Boutique service is not about size it is about precision. We deliver control, precision and accountability. Complex claims require more than scheduling logistics - they require clinical judgement expert matching an structured oversight

Why REI's traveling evaluator model works.

National network, local knowledge.

We operate across all Canadian provinces — but we don't treat every file the same. Regional nuance, specialist availability, and jurisdictional requirements are part of every referral we process.

Credentialed specialists who stand up in court.

Every assessor in REI's network is in good standing with their regulatory body. Their reports are prepared to withstand scrutiny — by either side.

Managed with personal attention.

From the first call to the delivered report, you have a named contact at REI who knows your file. You are not in a queue.

Long-term partners and clients.
