The appellants appealed the Director's decision to issue a Certificate of Property Use (CPU) for a former industrial property in Guelph, arguing that the CPU failed to adequately address the risk of contaminated groundwater migrating offsite to their adjacent properties.

The Tribunal found that while there was a risk of contaminant migration to one of the adjacent properties (10 Kingsmill), there was no risk of migration to the other (490 York).

The Tribunal held that the CPU's groundwater monitoring program and contingency requirements provided sufficient safeguards to address the potential for adverse effects, and that implementing physical barriers would be premature and potentially harmful given the complex fractured bedrock environment.

The Tribunal ordered minor amendments to the CPU to reclassify two monitoring wells as downgradient and to require the City to provide advance notice of groundwater sampling to the adjacent property owners, but otherwise confirmed the CPU.

The Appellant brought a motion to stay a Director's Order requiring it to take actions to address potential contamination at its property, pending an appeal.

The Tribunal found it had the authority to grant a stay under section 143 of the Environmental Protection Act, as the historic contamination did not pose an immediate danger to health or safety.

However, applying the RJR MacDonald test, the Tribunal denied the stay.

The Appellant failed to establish irreparable harm, as its financial costs were potentially recoverable in ongoing civil litigation and did not outweigh the public interest in identifying and managing the source of trichloroethylene contamination.

The appellant brought a motion seeking an interim stay of a Director's Order requiring it to undertake actions to address contamination on its property.

The parties agreed to stay several items, but disputed whether Items 8 and 9, which required a Groundwater Monitoring Program and Report, could be stayed.

The Tribunal found that the items, as they related to existing wells, constituted an order to monitor, record, and report, which cannot be stayed under section 143(2)(a) of the Environmental Protection Act.

The motion for an interim stay of those items was dismissed, though requirements relating to newly installed wells were stayed pending the main motion.
