Can my landlord refuse to lower my rent if the heating bills go down?

Jurisdiction: Canada • Practice Area: Tenancy Law • Responsible editor: Cong Ho• Published November 6, 2026

Quick Summary

Yes, you may be entitled to a rent reduction. If your rent increase was specifically due to an extraordinary increase in utility costs, the law requires the landlord to lower your rent if those costs drop by a certain amount.

The situation

I live in an apartment complex in Ontario and my landlord recently raised my monthly rent by $85 because of a massive spike in the building's utility costs last winter. This increase happened back in November of last year after a formal process was followed. However, since the weather has been much milder this spring, I noticed that the overall heating and electricity costs for the entire building have dropped significantly over the last four months. I actually checked the notice board in the lobby where they post some general building expenses, and it looks like the utility expenditure has fallen by a huge amount compared to what they claimed when they hiked my rent. I tried speaking to the property manager last week to politely ask if my monthly pay cheque could be adjusted downwards to reflect these lower costs, but they just brushed me off and said the increase is permanent. I am feeling quite frustrated because it feels unfair to keep paying a premium for services that are costing them much less now. I need to know if I am actually entitled to a rent reduction if the building's utility expenses decrease by a certain amount, or if they can just keep the extra money for themselves.

Detailed Analysis

Under the Residential Tenancies Act, there are specific rules for rent increases tied to utility expenses. Because your $85 monthly increase happened after a formal process following a spike in building utility costs, it likely falls under the rules for increases due to 'extraordinary increase in the cost for utilities'[1].

The law states that "If a landlord increases the rent charged to a tenant... and the cost of utilities for the residential complex decreases by more than the prescribed percentage in the prescribed period, the landlord shall reduce the rent charged to that tenant in accordance with the prescribed rules"[1]. This means that if the utility expenses for your building have dropped significantly—as you observed on the lobby notice board—the landlord cannot simply keep the extra money for themselves if the decrease meets the legal threshold.

However, whether you are entitled to a reduction right now depends on several factors. First, the law applies to increases permitted under specific orders regarding extraordinary utility costs[1]. Second, the reduction is only mandatory if the decrease meets a "prescribed percentage" during a "prescribed period"[1]. This refers to specific mathematical thresholds and timeframes set by the government that determine if a drop in costs is large enough to trigger a mandatory rent decrease.

It is also important to note that a landlord is prohibited from charging more than the lawful rent[2]. If the utility costs have dropped so much that the current rent no longer reflects the actual costs allowed by the original order, the landlord may be in violation of this rule.

Please note that state, provincial, or local laws may add further rules regarding rental agreements and utility billing.
