Western Canada’s propane inventories at the end of December 2025 (red line and text in left hand chart below) were posted at 5.3 MMbbl, with a less than average decline of 0.8 MMbbl versus November and stood 0.8 MMbbl (-13%) below the five-year average (blue line) according to data from the Canada Energy Regulator (CER). The smaller than average decline in the month likely reflected very strong propane production on the back of natural gas output in Western Canada that was near a record and contrasted against weather that was colder than average, with regional heating degree days (a measure of how cold were temperatures) that were 21% greater than last year and 9% more than the 30-year average. Preliminary estimates suggest that Western Canada's output of propane in December was near or above the record high of November.
