Canadian natural gas storage is nearly full heading into a winter that could be unusually warm, which would weigh on already-weak western Canadian prices.
Western Canada: As of Sept. 21, RBN Energy estimated that Alberta storage stood at 501 Bcf, or about 89% full versus working gas capacity. Based on five-year average injection rates for the remainder of the injection season, RBN predicted about another 20 Bcf can go into storage. RBN Energy Managing Director, North America, Martin King told NGI there was “plenty of gas on hand for the next winter” in Western Canada, adding that the “real kicker” would be a warmer North American winter driven by a potential “super” El Niño. Meteorologists increasingly expect weak heating demand, which would make western U.S. imports of Canadian gas more important for supporting prices. The Rockies imported 3.58 Bcf of Canadian gas Wednesday, and net border flows rose to 5.12 Bcf from 4.04 Bcf on Sept. 19. NOVA/AECO C winter 2026/27 forward basis averaged -$1.772/MMBtu.
Ontario: Storage is still pulling in U.S. gas ahead of winter, with 1.54 Bcf imported from the Midwest Wednesday. King said the province’s storage should “reach very comfortable levels for the end of October.” As of Monday, RBN estimated there was 258 Bcf in Ontario storage, about 86% full and on track for 94% capacity at the end of the injection season. “All very normal for the end of October for Ontario,” King said. Dawn winter 2026/27 forward basis averaged -15.1 cents.
