How Often Should a Chimney Actually Be Cleaned?
Resilience and safety · PROBLEM-FIRST
Ontario's Municipal Fire Prevention Officers' Association (OMFPOA), the province's own network of municipal fire prevention officers, publishes wood-heating and chimney safety tips directly on its own site. Its guidance states plainly to "have the chimney inspected and cleaned on a regular basis" and that "clean chimneys don't catch fire," and it recommends engaging a certified chimney sweep for that work, at minimum annually. OMFPOA's own guidance also names what actually causes the creosote buildup a chimney cleaning removes: restricted air supply, unseasoned wood, and cooler-than-normal chimney temperatures, along with closed glass fireplace doors or an inadequately open damper, a wood stove's damper or inlet restricted too far, and fully packed wood loads. Its prevention tips call for burning only seasoned wood, building smaller and hotter fires that burn more completely and produce less smoke, and installing a stovepipe thermometer to monitor flue temperature where a wood stove is in use, since a fire running too cool is one of the conditions that speeds up creosote formation. None of this replaces the certified sweep's own inspection and cleaning; it is the reasoning behind why that visit matters and what a homeowner can do between visits to slow the buildup down. This page does not state a chimney-fire count or a Niagara-specific wood-heating rate, because no OMFPOA figure or other checkable source for either number was found in this research pass.

Who this isn't for
This is not for anyone who has already confirmed, or reasonably suspects, a chimney fire has occurred, or whose chimney has known structural damage or a cracked flue tile; those situations call for a certified chimney sweep's own inspection before any DIY tool touches the flue, not a product from this page. It also does not cover pellet-stove or gas-fireplace venting, which are different systems with different maintenance needs than a solid-fuel wood chimney, and it does not cover the wire brush option for a metal-lined chimney, which the brush's own manufacturer advises against.
