Ontario approves amended Permit to Take Water for Royal Canin Canada’s Puslinch facility, confirming combined daily groundwater limits and environmental oversight.
Royal Canin Canada Company has received approval from Ontario’s Ministry of the Environment, Conservation and Parks (MECP) to amend its Permit to Take Water (PTTW) for its pet food manufacturing facility near Guelph, Ontario, following weeks of public consultation and local review.
The amendment applies to Royal Canin’s facility at 100 Beiber Road in Puslinch, just south of Guelph, and relates to groundwater use for pet nutrition processing. The updated permit allows the company to operate two on-site wells under a single, clearly defined daily withdrawal limit, addressing earlier concerns about potential increases in water use.
Under the revised approval, the facility may withdraw up to 240,000 litres of groundwater per day, with the total combined withdrawal from both wells not exceeding that limit. Each well is authorized for a maximum pumping rate of 333 litres per minute over a 24 hour period, but the permit explicitly caps overall daily usage to the long-standing allowance.
The permit amendment runs for 10 years, expiring in March 2036, and designates one well as the primary supply while the second serves as a backup to ensure operational reliability should the primary well require maintenance or experience disruption.
Why the Amendment Was Needed
Royal Canin originally applied to amend its existing permit in late 2025 to add a second well as a backup source. While the company stated that it did not intend to increase total water consumption, early documentation included a table that appeared to permit up to 480,000 litres per day—effectively doubling the allowable withdrawal if both wells were operated at maximum capacity.
That discrepancy raised concerns from Wellington Hydrogeology (WHL) and municipal officials, who flagged the amendment when it was presented to Puslinch Township council. Consultants warned that unclear wording could allow higher water takings than previously approved if permit conditions were not tightened. [guelphtoday.com]
The application was subsequently revised to confirm that the 240,000 litre daily limit applies collectively, not per well, resolving the ambiguity identified during the review process.
The amended permit is classified as a Category 3 PTTW, the highest risk category under Ontario’s water permitting framework. Category 3 permits are assigned to water takings with the greatest potential to cause environmental impact or interference, particularly in sensitive hydrogeological areas.
The Royal Canin facility is located within a wellhead protection area and a significant groundwater recharge zone, which triggered enhanced technical review and public consultation through the Environmental Registry of Ontario earlier this year.
Despite the classification, Wellington Source Water Protection and Wellington Hydrogeology have indicated that Royal Canin’s existing permitted water use is considered sustainable, provided the combined daily withdrawal does not exceed the established limit.
As with all Permits to Take Water issued under Ontario’s Water Resources Act, the approval includes operational and reporting requirements. Royal Canin must record daily water withdrawals, submit annual usage reports, and immediately notify MECP of any complaints or evidence of interference with nearby wells or groundwater supplies.
The permit does not guarantee renewal upon expiry, and it does not confer permanent water rights. Any future changes to withdrawal volumes or sources would require a new application and additional regulatory review.
Broader Relevance for Agriculture and Food Processing
While the amendment applies to one specific pet food manufacturing facility, the decision is being closely watched by Ontario’s broader agri-food sector, where processors increasingly face scrutiny over water use, environmental risk, and community impact.
The case showcases how industrial water permits for agriculture and food are evaluated, amended, and constrained—particularly in areas with vulnerable aquifers. It also underscores the importance of clarity in permit language to avoid unintended changes in water allocations that could affect surrounding agricultural operations.
