Ontario Science Centre Visiting Hours, Tickets, and Guide to Toronto Historical Sites

Date: 14/06/2025

Introduction

The Ontario Science Centre (OSC) has long been a cornerstone of scientific education and architectural innovation in Toronto. Established in 1969 as part of Canada’s centennial celebrations, the OSC pioneered hands-on, interactive exhibits, revolutionizing how science is experienced by visitors of all ages. Designed by Raymond Moriyama, the Centre’s integration with the Don River valley and its modernist-brutalist architecture have cemented its reputation as both an educational hub and a city landmark (Azure Magazine; Moriyama & Teshima Architects).

Today, as the original Don Mills location closes due to structural concerns, the OSC continues its mission through pop-up science events and digital programming, while preparing for an exciting new chapter at Ontario Place, expected to open in 2028. This guide covers everything you need to know about the OSC—its history, hours, tickets, accessibility, must-see exhibits, and travel tips—so you can make the most of your science adventure in Toronto. Always refer to the official Ontario Science Centre website for the most current information.

Origins and Historical Context

Centennial Project and Early Planning

The Ontario Science Centre, originally named the Centennial Centre of Science and Technology, was conceived in the early 1960s during a period of rapid urban growth in Toronto. It was envisioned as a flagship centennial project to foster a distinct Canadian identity through science and technology. Planning started in 1961, and by 1964, Ontario Premier John Robarts announced its creation, aligning with nationwide efforts to establish significant public institutions (Wikipedia; Kiddle; Azure Magazine).

Construction and Opening

Designed by Raymond Moriyama, the Centre’s construction began in 1966, with its doors opening in 1969. The location at 770 Don Mills Road was chosen for its dramatic ravine landscape, which became central to Moriyama’s architectural vision (Azure Magazine).

Pioneering Interactive Science Education

From its inception, the OSC broke from traditional museum models by focusing on interactive, hands-on exhibits. This approach made science accessible and engaging, influencing science museums worldwide (Azure Magazine).

Architectural Significance

Site-Specific Design

Moriyama designed the OSC to harmonize with the Don Valley’s natural contours. The campus features three interconnected buildings, bridges, and walkways that immerse visitors in both architecture and nature (Moriyama & Teshima Architects).

Modernist and Brutalist Influences

The OSC stands as an exemplar of modernist-brutalist architecture, characterized by exposed concrete, geometric forms, and expansive use of glass. Its monumental presence and forward-thinking design earned it the Ontario Association of Architects Landmark Designation Award (Azure Magazine).

Interior and Visitor Experience

The building’s layout fosters exploration through non-linear exhibit halls, ramps, and bridges, encouraging curiosity and discovery (Moriyama & Teshima Architects).

Expansion and Signature Features

Over the decades, the OSC expanded to include the OMNIMAX® Dome Theatre (1996), the Science Arcade, the Living Earth exhibit, and the Weston Family Innovation Centre, solidifying its place as a leader in science education (Wikipedia).

The Centre is listed on Toronto’s Heritage Register, with ongoing advocacy for its preservation (Azure Magazine).

Recent Developments and Relocation

Why Did the Ontario Science Centre Close?

In June 2024, the Don Mills location was closed due to urgent structural safety concerns, notably the risk of roof collapse. Repair costs were prohibitive, and deferred maintenance had accumulated over years (Wikipedia). The closure impacted local communities and prompted immediate program relocations.

Relocation to Ontario Place

The OSC is moving to a new, state-of-the-art facility at Ontario Place, scheduled to open in 2028. The new centre will feature modern exhibits, expanded programming, and integration with other waterfront attractions (Ontario Science Centre Relocation).

Interim Options

Until the new facility opens, the OSC continues to offer:

Pop-up science events across Toronto and Ontario
Virtual programs for schools and families
Outreach via community partnerships

Infrastructure Ontario is evaluating interim locations for future programming.

Educational Programs and Community Engagement

The OSC is a leader in hands-on science learning, offering:

Curriculum-aligned workshops and teacher resources (Ontario Science Centre Teacher Resources)
KidSpark STEM play areas for young learners (Destination Ontario KidSpark)
Science festivals, special exhibits, and community outreach (Ride On Canada)
