Impact AI 2026

For Impact AI Montreal 2026, Vooban created an immersive and seamless experience, reflecting its leadership in artificial intelligence.

For Impact AI Montreal 2026, Vooban aimed to provide an immersive experience befitting its position in artificial intelligence. The challenge was to transform the venue into a cohesive, fluid, and distinctive environment, where each area, from the main stage to the content, networking, catering, and broadcast spaces, contributed to a seamless participant experience.

Altitude/C supported Vooban every step of the way, from space design to logistical, technical, and vendor coordination. By adapting the layout plans to the site's realities and incorporating strong experiential elements, such as the immersive tunnel and a prominently featured stage, the team created an engaging journey conducive to exchanges, learning, and content creation.

Divergences 2026

Divergences: an inaugural edition designed to bring together curious minds, foster exchange, and create lasting connections within the business ecosystem.

Launching a brand new event was a significant challenge. With no history, no established audience, and no previous editions to build upon, we had to design the Divergences experience from scratch while ensuring its financial viability. Engaging partners, selling sponsorships and tickets, and creating relevant programming required a constant balance between ambition, appeal, and operational realities. The success of this first edition also relied on rigorous coordination among all stakeholders to deliver a cohesive and professional experience right from its debut.

Altitude/C supported Latitude through every stage of the project, handling the planning, coordination, and execution of the event. The team orchestrated various logistical aspects, from participant reception to vendor management, from the networking cocktail to the exhibitor space, and also coordinated speakers and partners. Thanks to a strategic approach focused on user experience and value creation for all stakeholders, Divergences quickly established itself as a credible and promising initiative. The quality of execution, the relevance of the participant journey, and the abundance of networking opportunities laid a solid foundation for the event's growth and sustainability.

Securian Canada 2026

Three cities, one energy: an immersive experience to unveil Securian Canada's new brand identity.

To mark the launch of its new brand identity, Securian Canada wanted to engage its employees through a unifying experience rolled out simultaneously in Montreal, Toronto, and Burnaby. The challenge was to provide a consistent experience from coast to coast, while taking into account the specific realities of each site and fostering team buy-in for this important organizational transformation. The situation became even more complicated when the Montreal event had to be postponed less than 24 hours before its original scheduled date.

Altitude/C supported Securian Canada in the planning and execution of this national initiative by coordinating all operations, suppliers, and partners across the three cities. The team also designed immersive multimedia content to bring the new brand to life and create a memorable experience for participants. Thanks to the rapid implementation of a contingency plan and the integration of learnings from other sites, the re-launched event in Montreal benefited from an optimized experience, true to the brand's vision and aligned with the organization's engagement objectives.

Women Leading on Climat

Integration of Women Leading on Climate into the Montreal Climate Summit

Integrate the Women Leading on Climate event into the Montreal Climate Summit, by offering a distinctive experience to participants while maintaining the fluidity and balance of the main event.

Altitude/C quickly reconfigured the spaces and reception flows to absorb 80 additional participants, updated the seating plan and the participant path, and ensured alignment between the new client team and the constraints of the existing event. The result: a smooth integration that expanded the Summit's audience and enriched its programming.

Montreal 2026 Climate Summit

The 2026 Montreal Climate Summit: when the diversity of voices is transformed into a collective commitment to the climate.

Orchestrating complexity in order to bring out clarity: this was the challenge of the Montreal 2026 Climate Summit. Behind a single event, dozens of stakeholders with distinct goals, who needed to align, mobilize and speak with one voice around a common commitment to climate.

Altitude/C has taken the lead in production on several fronts, placing coordination at the heart of every decision. Visual identity, scenography, audiovisual, video content: each element has been designed to serve a coherent and immersive experience, up to the challenges raised by the event. Strategically, the team contributed to structuring the programming and integrating exhibitors and partners into a fluid and engaging journey, transforming the diversity of intentions into a single collective impetus.

We’re Getting Old. Our Event Formats Might Be Too.

The room is full. The program is solid. But somewhere between the opening remarks and the final slide, the energy is more tenuous than before. Something has changed, and ignoring it is starting to cost us a lot.

What is a Professional Congress Organizer (PCO)?

A professional congress organizer (PCO) specializes in the strategic planning and complete management of large-scale congresses: scientific, medical, professional, or governmental. Unlike an event agency that handles the production of corporate events, a PCO works directly with associations and professional societies to achieve their strategic objectives while reducing the workload on their internal teams.

What is the difference between a PCO and an event agency?

An event agency designs and produces experiences: launches, galas, corporate events. A PCO goes much further. It takes charge of the entire lifecycle of a congress, from initial strategy to managing registrations, abstracts, sponsorships, accommodations, and on-site operations. It is an end-to-end management partner, not just a production vendor.

When should I bring in a PCO?

As early as possible, ideally 12 to 18 months before the congress takes place. This window allows you to secure the best venues and destinations, structure the program in advance, and maximize sponsorship and registration revenue. Reaching out to a PCO late often means playing catch-up. Reaching out early means building your congress on solid ground.
