SiteSummit: Summer School is the official event app for Canada's premier construction leadership conference — June 23–24, 2026 at George Brown College's Waterfront Campus in Toronto. Class is in session for 600+ of construction's top performers, and this app is your digital campus guide for everything happening across two days of high-velocity sessions, elite networking, and experiences you won't find anywhere else in the industry. BUILD YOUR SCHEDULE Browse the full two-day agenda and build a personalized schedule around the sessions that matter most to you. Get notified before sessions start so you never miss a keynote, breakout, or workshop. NETWORK WITH INTENT This is where SiteSummit separates itself. Access the full attendee list and request 1:1 meetings with the exact people you want in the room with you. Whether you're hunting for your next GC partner, subcontractor, or investor — stop leaving networking to chance. Book it in advance, show up prepared, and make every conversation count. EXPLORE THE CAMPUS Find your way around the venue, locate exhibitors in the Shop Class interactive floor, and discover what's happening in every corner of the event — from the main stage to the FIFA World Cup Viewing Lounge.

CONNECT WITH EXHIBITORS & SPONSORS Browse our partner and exhibitor directory, bookmark the companies you want to visit, and get the intel you need before you walk the floor.

WHO'S IN THE ROOM SiteSummit brings together the leaders shaping construction's future — from Canada's top GCs and specialty contractors to owners, developers, engineers, and the technology companies building the tools they use. PCL, EllisDon, Bird, Graham, Ledcor, Pomerleau, and hundreds more will be represented across two days. THE EXPERIENCE SiteSummit: Summer School isn't a conference. It's a campus. Expect theatre-style keynotes from the industry's brightest minds, immersive exhibitor experiences, an Official FIFA World Cup Viewing Party, premium food and drinks, and enough recess activities — foosball, beer pong, and more — to remind you that the best deals happen when people are actually having fun. Download the app, build your schedule, book your meetings, and show up ready. The bell's about to ring.

Verdict
The clearest difference is in-app purchases: SiteSummit at none against Date Calculator's 4. SiteSummit also leads on update cadence (every 2 days vs every 5 weeks) and iOS requirement (16.0 vs 18.0). On price, ads and device support there is nothing between them.
