Quebec Launches Real-Time Gas Price Map as Study Links Stations to Childhood Leukemia

Key facts

• Quebec's energy board launched an interactive map on Wednesday showing real-time gas prices at all service stations.
• 2,671 retailers are registered on the platform; fines for non-compliance range from $1,000 to $4,000 for a first offence.
• Gas stations must update prices within five minutes of a change under the new regulations.
• A study led by Université de Montréal's Stéphane Buteau found living within 250 metres of a gas station raises childhood leukemia risk.
• The risk is highest for children living within 100 metres of a station, the study in Environmental Pollution reports.
• Benzene, a known carcinogen released during gasoline storage and refueling, is the primary concern.
• The platform stems from the Act to ensure responsible governance of energy resources, adopted in June 2025.
• Former economy minister Pierre Fitzgibbon pushed for the legislation after a 2024 government study.

New Online Tool Tracks Pump Prices Across Quebec

Quebec motorists can now compare gasoline prices in real time across the province, thanks to an interactive map launched Wednesday by the province's energy board. The platform, accessible on the regulatory board's website, allows users to zoom in on any area and view current prices at individual service stations. The initiative is part of the implementation of the Act to ensure responsible governance of energy resources, adopted at the National Assembly in June 2025. It arrives amid market fluctuations driven by the war in the Middle East, which have pushed pump prices higher. Energy board spokesperson Benjamin Bourque said 2,671 retailers were registered on the map as of the latest census. Under the new regulations, every gas station must post the prices it charges for gasoline and diesel, and update the information within five minutes of any change.

Fines and Enforcement for Non-Compliant Retailers

Retailers that fail to comply face fines ranging from $1,000 to $4,000 for a first offence. Bourque said the board is giving gas stations time to adapt but warned that violators will eventually be penalized. The board is also encouraging consumers to report discrepancies between the price displayed on the map and the price at the pump. Users should first notify the retailer; if the problem persists, they can file a report directly on the platform. The tool aims to boost transparency in the gasoline market and allow motorists to make more informed choices, according to the energy board. Former economy minister Pierre Fitzgibbon pushed for the legislative change following a government-commissioned study released in 2024.

Study Links Gas Station Proximity to Childhood Leukemia

Separate research published in the journal Environmental Pollution has found a significant association between living near gas stations and an increased risk of childhood leukemia. The study, led by Stéphane Buteau, a professor in the Department of Environmental and Occupational Health at Université de Montréal, examined Quebec's medical administrative databases to track newborns from birth. The researchers focused on gas stations because gasoline contains benzene, a known carcinogen linked to leukemia and other serious health risks in adults. Benzene, a natural component of crude oil, is highly volatile and released into the environment during gasoline storage, vehicle refueling and the unloading of tanker trucks. A 2023 Health Canada study concluded that exposure to benzene from gas station emissions may pose unacceptable risks to human health for people living nearby. However, the effects on children and the unborn have remained poorly understood until now.

Risk Increases with Proximity, Even After Adjusting for Confounders

The research team used three indicators to assess benzene exposure: the number of gas stations within a 250-metre radius of the child's postal code at birth, distance to the nearest gas station, and a composite measure of both distance and number. The results showed that living within 250 metres of a gas station is associated with a higher risk of childhood leukemia, even after adjusting for confounding factors such as socioeconomic status, living environment (urban versus rural) and maternal characteristics. "We also controlled for the fact that people living near gas stations are often close to busy roads," Buteau added. The risk increases with proximity and is highest for those living within 100 metres. Buteau, who previously served as a scientific advisor on environmental health at Quebec's public health institute (INSPQ), noted that only 5 to 10 per cent of childhood cancers are attributable solely to genetics. "The rest are due to other factors, particularly environmental ones," he explained.

Broader Context: Transparency and Health Concerns Converge

The launch of the price transparency map and the publication of the leukemia study come at a time when Quebec is grappling with both high fuel costs and growing awareness of environmental health risks. The new platform addresses consumer frustration over opaque pricing, while the research underscores the need for stricter regulations on gas station emissions. Buteau's project is funded by the Canadian Institutes of Health Research and involves a multi-institutional team examining the link between air pollution and childhood cancers. The study adds to a growing body of evidence that benzene exposure from gas stations poses a public health threat. The energy board's new tool may also help regulators monitor compliance with existing environmental rules, though its primary purpose is consumer transparency. The board has not indicated whether it will use the platform to track emissions-related data.

Outlook: Enforcement and Further Research Ahead

As Quebec's energy board begins enforcing the new price-posting regulations, it remains to be seen how quickly retailers will comply and whether fines will be imposed. Bourque's statement that the board is allowing a grace period suggests that enforcement will ramp up gradually. Meanwhile, Buteau and his team plan to continue investigating environmental risk factors for childhood cancers. Their findings may prompt calls for stricter vapour-control regulations at gas stations, similar to measures already adopted in some jurisdictions. The convergence of these two developments — one aimed at market transparency, the other at public health — highlights the multifaceted impact of gas stations on Quebec communities. For now, motorists have a new tool to save money, while parents have fresh cause for concern about what lies near their homes.

The bottom line

• Quebec's new interactive map lets drivers compare real-time gas prices at 2,671 stations, with mandatory updates within five minutes of a price change.
• Non-compliant retailers face fines of $1,000 to $4,000 for a first offence; a grace period is in effect before full enforcement.
• A study in Environmental Pollution found that living within 250 metres of a gas station increases childhood leukemia risk, with the highest risk within 100 metres.
• Benzene, a known carcinogen released during fuel storage and refueling, is the primary agent of concern; Health Canada previously deemed emissions risks unacceptable.
• The price transparency law was championed by former economy minister Pierre Fitzgibbon after a 2024 government study.
• The research, led by Université de Montréal's Stéphane Buteau, controlled for socioeconomic status, urban/rural setting, and maternal factors.
