UNESCO Says It Was Not Informed About Third Link Impacts

UNESCO announced on Wednesday that it has not received any notification regarding the potential impacts of the proposed third link infrastructure project. The statement was issued from the organization’s office in Montreal, referring specifically to the area around Cap Diamant in Old Quebec.

Old Quebec is designated as a UNESCO World Heritage Site, a status that reflects its historic urban fabric and cultural significance. The viewpoint from Cap Diamant is highlighted by UNESCO as part of the site’s exceptional value, offering a panoramic perspective that contributes to the heritage character of the district.

The third link project, a planned transportation corridor intended to improve connectivity across the region, has raised concerns among heritage professionals because of its proximity to the protected landscape. UNESCO’s lack of notification means the agency has not been able to assess whether the project might compromise the visual integrity or broader heritage values associated with the site.

In its brief release, UNESCO emphasized the importance of timely communication from authorities and developers when projects could affect World Heritage properties. The organization’s standard practice involves reviewing impact assessments to ensure that any alterations do not diminish the attributes that warranted the site's inscription.

The statement does not provide details on the project’s timeline, design specifics, or the entities responsible for its planning. It simply notes the absence of formal information sharing with UNESCO, leaving the agency unable to comment on potential outcomes.

Stakeholders in Montreal’s urban planning and heritage preservation sectors are expected to consider the UNESCO notice as they move forward with discussions about the third link. The situation underscores the procedural step of notifying international heritage bodies when developments intersect with protected sites.

As of the early morning of September 2, 2026, UNESCO’s position remains that it has not been informed about any assessments or mitigation measures related to the third link’s impact on the Cap Diamant view and the broader Old Quebec World Heritage landscape.
