The weekend before
Four early events open the calendar before the official start — the city is already leaning in.
Monday, June 1
The Kick-Off draws 854 registrations — the single biggest event of the week — and 17 more light up around it. Day one: 2,129 registrations.
Tuesday, June 2
39 events, 3,812 registrations — the biggest crowd day. Nespresso's Groundswell screening alone packs in 809 people downtown.
June 3–4
Thursday is the fullest calendar of the festival — 43 events in one day. Flagships on finance, energy, food and climate tech anchor 6,777 registrations across the core.
Friday, June 5
The flagship series closes with all 10 flagships at capacity, and the official celebration — The AfterGlow — brings 257 people together.
June 6–7
38 community events — ravine rides, garden socials, mural crawls — carry the week into the weekend, in the neighbourhoods where people live.

Who built it
TOCW didn't put on 199 events — 201 hosts did. Companies, labs, nonprofits and neighbours organized 189 community events on their own initiative, and collaboration ran deep: 64 events were co-hosted by two or more hosts. That's not an audience; that's infrastructure the movement keeps.

What it set in motion
A movement grows by widening, mixing, and holding on. This week did all three: 5,852 people were new — 86% of everyone who came wasn't at TOCW 2025. The rooms weren't silos: the median event held 7 sectors and 17 industries. And people went deep — 2,178 attended two or more events.

Versus 2025
+93% events — and 10 of 11 founding sponsors and 2 in 3 hosts came back for year two. Momentum, measured.
