The "When?"
Timeline of the Chin Reservoir Controversy
Federal Minister of Environment and Climate Change, Steven Guilbeault receives a request for federal review from 9 Alberta environmental groups, supported by the Blood Tribe/Kainai and Siksika First Nation.

Public engagement and commentary period for the PToR ended
Skepticism towards irrigation expansion projects due severe drought conditions
Irrigation districts double down that irrigation expansion will improved irrigation efficiency [10]
While the PToR included steps to consult with local Indigenous nations and assess impacts on aquatic habitat health, it was critiqued for lacking concrete steps to resolve identified impacts [16].
With more frequent droughts predicted for Southern Alberta, some are concerned that there won’t be enough water for the expanded irrigation infrastructure. [9]
Once the Supplemental Information Request response has been reviewed, public interest review processes will commence.
