Patients & Visitors

Everything you need to prepare for your visit to WHRN — from parking and wayfinding to what to bring and how to support a loved one.

Preparing for Your Visit

Whether you're coming to the emergency department, attending an outpatient appointment, or being admitted, we want your experience at WHRN to be as smooth as possible. Here's what to expect.

  • 1

    Confirm your appointment or referral

    Check your appointment letter or call the clinic directly. Bring your Ontario Health card (OHIP) and any relevant specialist letters. Arrive 15 minutes early for new patient visits.

  • 2

    Know where to park and enter

    All WHRN sites have accessible parking and clearly signed main entrances. Real-time parking availability is posted on the main entrance screens at Midtown and Queen's Blvd.

  • 3

    Check in at registration

    Upon arrival, proceed to the Patient Registration desk on the main floor. Bring your health card, a photo ID, and your appointment confirmation if applicable.

  • 4

    Bring your care partner

    WHRN actively supports care partners. One designated care partner may accompany inpatients throughout their stay. Additional visiting hours vary by unit — ask your care team.

  • 5

    Stay connected with your care team

    All inpatients are assigned a primary nurse and a most responsible physician (MRP). Daily care rounds typically happen in the morning. Don't hesitate to ask questions at any time.

What to Bring

For all visits, bring your Ontario Health Card (OHIP), a list of current medications including doses, your personal health devices (hearing aids, glasses, mobility aids), and comfortable clothing for inpatient stays. Do not bring valuables — WHRN is not responsible for lost or stolen items.

Who We Are

One network,
boundless
care.

Waterloo Regional Health Network (WHRN, pronounced "wren") was formed in April 2025 through the historic merger of Grand River Hospital and St. Mary's General Hospital — two of Waterloo Wellington's most trusted healthcare institutions.

Together, we are building a health system designed for a region expected to reach one million people by 2050 — one that delivers care that is personal, seamless, and continuously reimagined.

Our Story

Grand River Hospital and St. Mary's General Hospital have served Waterloo Wellington for generations — together delivering cardiac surgery, cancer care, mental health services, and emergency medicine to one of Canada's fastest-growing regions.

The decision to merge into a single health network — Waterloo Regional Health Network — was driven by a shared vision: to make it easier for patients to get care, to reduce duplication, and to position the region's healthcare system for the growth and complexity that lies ahead. The merger was finalized in April 2025.

Our Mission

To support the health and well-being of individuals and families across Waterloo Wellington and beyond — by making it easier to get care, innovating how care is delivered, and creating better experiences for everyone who comes through our doors.

Land Acknowledgement

WHRN provides care within the Haldimand Tract Treaty of 1784, which granted six miles on either side of the Grand River to the Haudenosaunee Confederacy. We are grateful to work on this land, and we are committed to reconciliation and to building relationships with the Indigenous communities we serve.

April 2025

Grand River Hospital and St. Mary's General Hospital officially merge to form Waterloo Regional Health Network (WHRN).

224,000+ Patients

In 2024/25, WHRN served more than 224,000 patients and provided nearly 741,000 patient visits across all sites.

10% of Ontario

WHRN's regional programs serve more than 10% of Ontario's total population — across Brant, Bruce, Grey, Haldimand, Huron, Norfolk, Oxford, and Perth counties.

19 Areas of Care

Including seven provincial Regional Programs — the largest concentration of specialized regional programs outside of a major urban centre in Ontario.

One Million by 2050

Waterloo Wellington's population is expected to reach 1 million by 2050. WHRN is building infrastructure, partnerships, and innovation capacity to meet that demand.

Our Values

What Guides Every Decision

Compassion

We treat every patient, family, and colleague with genuine empathy and respect — recognizing the whole person behind every health need.

Innovation

We are bold about reimagining care delivery — using technology, research, and creative problem-solving to build a better health system.

Inclusion

We are committed to equitable care for all — regardless of background, identity, ability, or geography. Health is a right, not a privilege.

Excellence

We hold ourselves to the highest standard in patient safety, clinical outcomes, and the experience of everyone who interacts with WHRN.

Our Leadership

Leading With Purpose

WHRN's leadership team is dedicated to building a health network as dynamic and diverse as the communities we serve.
