earlier projects like that at Bitumount also played a role in development. The company held a 36.75% interest in the Joslyn north oil sands project which was shelved pending an economic review by operator Total S.A. in May 2014. The Joslyn project was sold to CNRL in September 2018. The company also produces conventional oil, heavy crude oil, and natural gas. Refining In Canada, Suncor operates refineries in Alberta, Ontario and Quebec. The company's 135,000-barrel-per-day Strathcona, refinery runs entirely on oil sands-based feedstocks and produces a high-yield of light oils. A 137,000-barrel-per-day Montreal Refinery produces gasoline, distillates, asphalts, heavy fuel oil, petrochemicals, solvents and feedstock for lubricants. An 85,000-barrel-per-day refinery in Sarnia, Ontario produces gasoline, kerosene, jet and diesel fuels. A 98,000-barrel-per-day refinery in Commerce City, Colorado produces gasoline, diesel fuel and paving-grade asphalt. Retail Suncor's main downstream brand in Canada is Petro-Canada. Suncor previously operated and franchised retail locations under the Sunoco brand, but post-acquisition, nearly all remaining Sunoco stations were converted to Petro-Canada. In addition, the company terminated all of its independent Sunoco franchises, as it planned to implement Petro-Canada's model of requiring franchisees to operate multiple locations. Presently, at least one Sunoco branded station exists, and is located in Port Colborne, Ontario. A group of affected franchisees filed a class-action lawsuit over the matter, claiming that Suncor had violated Ontario's Arthur Wishart Act. However, the case was blocked by an Ontario court. In the United States, it operates retail outlets in Colorado under the Shell and Phillips 66 brands. On April 13, 2012, Suncor paid a $500,000 fine after being found guilty of price-fixing in Ontario. Aircraft fleet Suncor Energy owned and operated three Bombardier CRJ900ER aircraft but sold them in late 2016 and now uses Westjet to shuttle Suncor employees to the oilsands. As of February 2023, Suncor Energy owns a Bombardier Global Express (BD-700) and operate as ICAO airline designator JSN, and telephony JETSUN. Environmental record According to a Pollution Watch fact sheet, in 2007 Suncor Energy's oil sands operations had the sixth highest greenhouse gas emissions in Canada. While Suncor has reduced the greenhouse gas emissions intensity of its oil sands operations by more than 50% since 1990, total greenhouse gas emissions from the company's operations have increased because of growing oil sands production. On April 2, 2009, Suncor was fined $675,000 for failing to install pollution control equipment at its Firebag operation near
