Montreal data-centre market reference

Montreal's directory footprint includes downtown carrier hotels, airport-area and Technoparc facilities, suburban buildings and larger regional campuses. Cologix publishes MTL1 through MTL12 across Montreal, Verdun, Longueuil and Drummondville. eStruxture publishes five MTL facilities. Vantage and other operators add enterprise and campus records. These listings should be grouped by function rather than treated as interchangeable units.

Downtown locations can concentrate carriers and cross-connect opportunities. Larger edge sites can provide more floor area or power. A workload architecture may use both. The map shows official locality points, so several records overlap even when their source pages identify different buildings. Open the facility record and operator page before using the map for travel, construction or network planning.

Cologix publishes selected building-level figures. MTL9 is listed at 120,000 square feet and 25 MW, while MTL10 is listed at 180,000 square feet and 35 MW. Its MTL8 announcement states 21 MW. MTL12 publishes more than 8,000 square feet. These values make the pages less repetitive and help describe the portfolio. They do not prove current availability, customer-ready power or the capacity of an individual suite.

Where the operator source does not publish a facility-specific value, this directory leaves the field unverified. It does not borrow a metro total or divide a campus number across buildings. The same rule applies to certifications, commissioned year and ownership. A buyer can use the missing field as a document request and compare the response with the dated public source.

Large-power service begins with the applicable contract category and connection assessment. Hydro-Quebec states that Rate L and Rate LG have different use conditions even though both apply at 5,000 kW and above. Data-centre developers should not assume industrial eligibility. The load profile, business use, voltage and service arrangement belong in the rate discussion from the beginning.

For a new connection, Hydro-Quebec requires an official application through a qualified professional and directs large-power projects through the applicable assessment route. The utility response can define network work, schedule and commercial obligations. A building with visible transmission infrastructure nearby is not proof that a requested load can be served there.

A carrier hotel can reduce the distance and complexity of reaching networks, exchanges and cloud on-ramps. A larger campus may offer space for higher-density deployment, separate utility equipment and expansion. Montreal's facility pattern lets operators combine these roles through metro fibre. The public directory records operator statements about connectivity but does not claim that a listed network is available in every facility or product.

Location also affects construction access, staffing, maintenance travel and backup-fuel planning. A site near the airport has a different operating context from a downtown high-rise or a Drummondville campus. Those differences cannot be reduced to a province score. A shortlist should record the exact operational reason each site is included.

Hydroelectric supply does not remove the need for UPS coordination, generator testing, bypass design, selective protection or battery-environment control. The site team must know how the critical-power chain behaves during utility disturbances and planned maintenance. Public facility pages rarely disclose enough detail to assess that chain. This directory therefore sends technical planning to the maintenance workspace rather than inventing equipment facts.

Cold weather can support economized cooling, while winter peaks and freeze conditions add other constraints. Review cooling mode transitions, heat rejection, generator starting, fuel systems and access after snow events. Treat climate as an engineering input, not a promise of efficiency. Operator efficiency claims should be checked against the facility, measurement boundary and period they describe.

Start with network and workload requirements, then separate interconnection nodes from primary compute sites. Compare the published facility specifications, source date and publication state. Confirm available power, cabinet or suite density, cooling limits, carrier list, cross-connect timing, security controls and expansion rights directly with the operator. A sourced public value is a question anchor, not a commercial offer.

The facility list below includes records in the wider Montreal operating area used by this guide. It is not a market-size estimate. The change ledger records when fields were added or revised, and the sitemap includes only the reviewed batch. That separation lets the directory expand coverage without pretending that every new record is ready to rank.
