Many Ontario residents may need to budget for higher heating bills starting in early 2026. Enbridge Gas Inc. has formally requested approval from the Ontario Energy Board (OEB) to raise its natural gas distribution rates, a move that would affect a wide range of residential and commercial customers across the province.
The proposal, announced in a recent customer notice, outlines increases that are set to take effect on January 1, 2026, pending OEB approval.

Why Are Rates Going Up?
Formula Tied to Inflation and Operational Efficiency
According to the notice, the rate increase is calculated using a formula already approved by the Ontario Energy Board. This formula factors in inflation, utility performance, and efficiency measures, all aimed at ensuring the delivery of reliable and cost-effective energy services.
Enbridge emphasized that the proposed adjustments are essential for maintaining infrastructure, supporting safe energy delivery, and meeting evolving energy demands.
