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.

5 ans à construire un événement qui rassemble celles et ceux qui agissent concrètement pour la transition climatique.

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.

2026 International Aerospace Innovation Forum

The International Aerospace Innovation Forum brought together nearly 1,500 participants to discuss the future of the Quebec and global aerospace industry.

Orchestrate a second edition of a large-scale event with multiple simultaneous components: nearly 1,500 participants, 70 speakers, an exhibition hall integrating complex technological equipment, and an experiential cocktail celebrating 100 years of Quebec aerospace history. While clearly distinguishing itself from the previous edition creatively and technologically.

Altitude/C orchestrated all operations with an integrated approach, ensuring close coordination between the technical, logistical and multimedia teams. On the creative side, the production of immersive content deployed in the plenary room and during the cocktail significantly raised the standards of the previous edition, delivering a fluid and distinctive experience that matches the positioning of the Forum.

Vooban Impact IA 2025 Toronto

Logistic coordination and decor management for a reference event in artificial intelligence.

Deploy Impact IA Toronto by maintaining visual and logistical coherence with Montreal publishing, while dealing with the constraints specific to off-market event production.

Altitude/C took charge of the design of the room plans and the overall layout, coordinated the preparation and installation of the sets, and ensured follow-up with external suppliers throughout the process. Ongoing operational support, from planning to dismantling, allowed for a smooth implementation and a professional visual presence, fully aligned with Vooban's identity and the Impact IA universe.

30th Anniversary Ambassadors Circle

Gala celebrating the 30th anniversary of the Quebec Ambassadors Circle: a tailor-made evening, record attendance and a video clip to inspire the next generation.

The Quebec Ambassadors Circle wanted to mark its 30th anniversary with a unifying gala evening, bringing together its entire community of ambassadors around a moment of celebration and recognition. The event was intended to both honor the journey of current and past members, reinforce the sense of belonging to the Circle and project an inspiring image to attract the next generation.

A completely tailor-made evening, designed to highlight the commitment of current and past ambassadors. Close collaboration with local partners and flawless technical execution made it possible to achieve record attendance, while the video clip produced on site fed into future canvassing efforts.

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.
