Chimney Issues

Update – Dec 2019

SAHRA sent an email to Mr. Gregory Zimmer, Manager of Building Code Policy, Ministry of Municipal Affairs and Housing on Dec 14, 2019.  We attached the letter to MPP Martin and MP Mendicino in Nov, 2018 along with the write-up on The $10K Chimney Surprise. We explained that we had asked them to help the City of Toronto, Residents’ Associations and Residents in their requests dating back to 2006 and 2012 for a Building Code Change (Change Request Forms are on file) to deal with the unfair Chimney Issue caused for an existing homeowner when a New Build occurs beside their property.

SAHRA has followed the Ontario CodeNews for years, watching for this issue to be dealt with in each year’s review (we have been told that our Change Requests roll forward automatically).

In the Oct 23, 2019 CodeNews Issue 288 it stated that the National Code consultation would include changes relating to ‘Spatial Separation Between Houses’.  We asked if this discussion would deal with the Chimney Issue problem due to the lack of space between houses in conjunction with the height of the new house compared to the chimney height of the existing home?

We have not given up on trying to arrange for an amendment to reduce the unanticipated financial impacts on homeowners of surrounding infill projects who may be required to relocate their existing chimney or install a high efficiency furnace or remove or change gas fireplaces vented through the chimney as a result of the requirements of the National Gas and Propane Installation Code.  The neighbouring properties should enter into agreements as to the action(s) to be taken and the appropriate reimbursement to the impacted homeowner by the party developing the adjacent infill property.  The problem initially surfaced with two-storey developments beside bungalows but it continues as now the new builds are taller than existing two-storey homes.  It is not just a City of Toronto issue.

Mr. Zimmer has been asked to provide assistance/information on how/when the Chimney Issue will be addressed.


Update – Nov 2018

In Nov, 2018, SAHRA submitted a request to MP Marco Mendicino and MPP Robin Martin for assistance as our Federal and Provincial representatives in getting the Change Requests submitted in 2012 to be considered for revision to the model National Building Code and the Ontario Building Code.

MPP Martin responded referring us to a staff member within the Ministry of Municipal Affairs and Housing – she was not offering to follow-up on the issue.  We have not received a response from MP Mendicino.

Write-up on the Chimney Issue The $10K Chimney Surprise (SAHRA) Nov 2018



The $10K Chimney Surprise!

Some ‘small house’ residents have already been through the experience of learning about the Natural Gas and Propane Installation Code and Ontario Regulation 212/0 – Gaseous Fuels!  Their furnaces have been or have been threatened to be ‘red-tagged’ as their chimney is used for venting of gas furnaces/boilers or gas fireplace logs/inserts…because a new house is going to be built/or has been built on their chimney side.  The ‘existing’ homeowners have learned that they have no recourse but to proceed with extending their chimney or replacing their gas-fueled systems at their own cost!   

The Code (both Ontario and National) says “Natural (gravity) and motor induced draft type gas burning appliance chimney installed closer than 8’ from the vertical wall, must extend a minimum of 2’ above the roof placed over that wall.” The City’s minimum required side yard setback is 1.2m (3.94’) so the 8’ requirement would never be met.

The maximum building heights vary across the provinces/areas but the City of Toronto’s maximum building height is 8.8m and variances are now being granted in some wards for over 9.3m.  In a common bungalow or storey-and-a half and in some cases even an old two-storey situation, this would call for extending the chimney height from the roofline to a height which is not feasible unless bracing was installed.  Some homes have actually done this!  The alternative is that the furnace/boiler must be replaced with a new unit that can be direct vented through the outside wall; gas fireplace units also need to be replaced (if feasible) with direct vented models.  The cost for doing this can range between $6,000 to $10,000….an unforeseen (and unfair) expense for the ‘small house/existing’ owner.

There are many more homeowners that may not even be aware that they are facing potential problems (the Building Code regulation exists for a reason)and major costs due to this issue…..they won’t be aware of the problem likely until the situation is noticed by a gas provider or servicer.  The gas/service provider is then obligated by virtue of their license requirements to ‘red-tag’.  This means that the homeowner has to ‘correct’ the situation within 45 days or their gas supply will be cut off.

The City of Toronto Building Department recognized this as an issue in 2007.  A Staff Report to the Planning and Growth Management Committee stated “As the City of Toronto continues to develop and intensify, occurrences of infill housing construction affecting adjacent existing properties will continue.  It is not acceptable for homeowners adjacent to infill housing projects to have their chimey installation be deemed unsafe, and through no fault of their own, be forced to make expensive modifications to their homes or chimneys.”  Council at that time endorsed a Code Request endorsing an amendment to the Ontario Building Code.

Staff Report Adverse Impacts-Chimneys
Chimney Change Request City of Toronto

Back in 2009, Bob Aaron (Aaron & Aaron, Barristers and Solicitors) reported on the ‘Benjamin problem’ and the results of the City of York appeal to the Ontario Court of Justice back in 1995.  He has questioned whether Justice Dennis Lane’s ruling was correct in law.  If so, he has suggested that Queen’s Park should amend the Building Code Act.  See the December 26, 2009 article titled “Aaron:  Amend code to protect innocent neighbours”.

But this is not just a City of Toronto problem….this situation is allowed to occur because of the lack of consideration for the building-next-door in both the Ontario and National Building Codes.  Any ‘small house’ owner in this situation across the city could be ‘red-tagged’ at any time.

For this reason, the issue was presented to both FoNTRA (the Federation of North Toronto Residents’ Association) and CORRA (the Confederation of Resident and Ratepayer Associations) to get their help in obtaining the attention of both the Ontario and Federal govenments.  They agreed that an appropriate Building Code change needs to be put in place that makes the developer responsible for funding the necessary work that an adjacent property would be forced to do to comply with Code and TSSA safety regulations.

A template for an Ontario Building Code Change Request form has been prepared (click below for a MS version of the document) with all the required information for the MMAH.  We need all concerned citizens to submit a Request so the MMAH realizes that this is an important issue that needs to be dealt with under the Ontario Building Code.  Modify the Contact Information on Page 1 of the Request Form and then email the modified Request to Alek Antoniuk at the MMAH ([email protected]).  

Please contact [email protected] if you have questions or need further instructions.

Ontario Building Code Change Request

Please help in highlighting the issue to the MMAH so that an appropriate Building Code change is put in place that will make the developer responsible for funding the necessary work that an adjacent property would be forced to do to comply to Code and TSSA safety regulations.



Update as of Jan, 2018

As per the required process, Change Requests were submitted to the Ministry of Municipal Affairs and Housing in 2012 to be considered in the “next opportunity for consultation on code changes to Ontario’s Building Code”.

SAHRA followed up again in Nov, 2015 as Ontario Building Code News 239 on Oct 20, 2015 stated that Nov 30, 2015 was the cutoff date for Code Change Requests for Net Edition Building Code.  The Ministry replied that we did not have to re-submit – our previous submission on file would be considered in this round. They also stated that once a proposal is in their system, they cannot provide information on its status.

SAHRA followed up again in Nov, 2018 asking for an update on the current status of our request – no response from the Ministry of Municipal Affairs and Housing.

SAHRA has followed each Ontario Building Code News Issue as published – still nothing!

Over the years, a number of residents have contacted SAHRA about gas furnace/boiler, gas fireplace as well as wood burning fireplace problems (they actually require more clearance than gas flues – 10′ versus 8′).  Our advice to them is to try to negotiate with the developer, before the CofA Hearing.

Eventually the problem will go away but likely not for quite a long time.  Keep in mind that this is a provincial/federal issue (it is not just Toronto) and it will take many years before the bungalows and the older 2-storey homes convert to high-performance gas furnaces/boilers or eliminate their wood-burning fireplace or are all eliminated.  In Toronto, the bungalow issue will be resolved first as the bungalows are being eliminated rapidly.  But not they are also starting to replace 2-storey homes with new buildings that are much higher than the existing 2-storey home(s) beside them, so same problem.


Actions Required Now (2013 and 2014)

It is now time to follow-up on this issue with the Minister (The Honourable Linda Jeffrey) and Deputy Minister (Laurie LeBlanc) of the MMAH asking for action/progress in 2013 by the consortium of residents’ associations.

MPs and MPPS and City Councillors all need to be made aware of this situation, the impact on their constituents and our requests to the various levels of government.

In the meantime, we also need to continue to educate the unsuspecting ‘existing’ homeowner of this situation so that they have an opportunity to negotiate a financial arrangement with developers before the Committee of Adjustment hearing and/or before development begins.  The developers/ architects often say/pretend that they are not even aware of the chimney issue!

We have asked the City of Toronto to review the ‘notes’ on permit drawings that now state “However, please take note that once the authorized construction is completed, the subject building may be in close proximity to the existing chimney on the adjacent property.  This may have a negative impact on the operational effectiveness of the said chimney.  Please be advised that it is the City’s position that this would be a civil matter between the owners of the two properties which does not involve the City nor fall within the City’s jurisdiction.  As such, it is advisable that you confer with the owner of the adjacent property prior to proceeding with the construction”. The City should also state that the ‘existing’ homeowner could be red-tagged and have to replace/remove their boiler/gas fireplaces at a substantial cost.  It is not often that the existing homeowner would even see the final permit drawings but at least it does make the developer aware of the situation that he should discuss with the adjacent homeowner.

SAHRA also asked Councillor Karen Stintz in Oct, 2012 to follow-up on the City including a statement on the Notice of a Committee of Adjustment hearing IF there is a chimney problem with the adjacent property, so that the adjacent homeowner as well as the developer are aware of the situation and as such can proceed with negotiating a plan for dealing with the problem and a financial agreement.

The Action Items to be followed up in 2014 are:

  • Determine with MMAH officials what the process and timings are for 2014 Building Code changes.
  • Resubmit the issue to the Minister and Deputy Minister of the MMAH supported by CORRA, FoNTRA, F.U.N. (Federation of Urban Neighbourhoods), SAHRA and additional GTA residents’ associations.
  • Present the issue to all MPs and MPPs.
  • Present the issue to all City of Toronto Councillors.
  • Present the issue to the City of Toronto Building and Planning Departments.
  • Present the issue to the Building Industry and Land Development Association to ask that their members recognize the need to negotiate arrangements with affected adjacent homeowners.
  • Present the issue to the Building Advisory Council (BAC) for dissemination to their members.
  • Inform the Toronto Real Estate Board of the issue asking them to make their agents aware of the issue and the possible implications to their buying clients.
  • Arrange a meeting of all involved parties to determine what actions can/should be taken to resolve this situation.
  • Publicize the issue via various techniques/media to the residents of the City of Toronto.
  • Follow-up with the Committee of Adjustment request that any chimney issue be noted on the Notices so that the developer and the adjacent homeowner are aware of the situation.
  • Follow-up with the City of Toronto Building Department request that the ‘red-tag’ problem is noted on the final building permits so that the developer is aware of the need to discuss the situation with the adjacent homeowner.

We will now re-initiate the campaign for a Building Code change with the hope that we can achieve changes in 2014!


Updates since January, 2012

FoNTRA (represents 28 member organizations), CORRA (represents 50+ member organizations), SAHRA (represents 800 households in the South Armour Heights area) as well as a number of the other Associations and a number of members of those Associations submitted Requests to the Ontario MMAH in Jan and Feb, 2012, supporting the original Request submitted by the City of Toronto in 2007.  A confirmation letter/email from Alex Antoniuk, Manager, Code Development Unit, MMAH to the submitters stated that the “code change request will be considered at the next opportunity for consultation on code changes to Ontario’s Building Code.  Typically there are several opportunities in each Code cycle.”

Brian Abbey, a member of FoNTRA and also a member of the Building Advisory Council (BAC), was advised by the MMAH that it was never included in the Ministry’s round of code consultations in 2011 because the wording in the Ontario Building Code (OBC) is exactly the same as the model National Building Code (mNBC) and would need a change to the mNBC for a change in the OBC.  Alek Antoniuk of the MMAH advised FoNTRA on Jan 30, 2012 that the proposed change has been forwarded to the Canadian Codes Centre for consideration as a change to the mNBC and that the request would be considered at the next opportunity for consultation on code changes to the OBC.  FoNTRA also received a phone call from Ottawa in Feb, 2012 and an electronic version of the Request was sent to them.

CORRA submitted a Request on Feb 21, 2012 with copies to The Honorable Kathleen Wynne and Ann Borooah, Chief Building Official & Executive Director, City of Toronto pointing out that this has been a longstanding issue; first brought forward by property owners on a site-by-site basis; then as an issue brought forward as a neighbourhood concern; and now it is being raised to resident and ratepayer associations on a city-wide basis.  We need a timely resolution to this issue. CORRA asked to be kept informed on progress of this issue being reviewed/resolved.

We hoped that we would now have the attention of both the Ontario and Federal government agencies and that Building Code changes would be forthcoming but that does not appear to be so.  Follow-up on March 6, 2012 to the submissions resulted in a response from Ralpha Digaetano, Code Development Advisor, MMAH advising that “at this time no new public consultations on additional proposed code changes for the next edition of the Building Code are planned.” and that “This issue raises questions concerning Zoning By-laws, common law, and TSSA fuels safety enforcement, as well as the need for review of the Building Code. We are still determining how to address your concerns and whether a Building Code amendment will be the most suitable means of addressing your concerns.” 

FoNTRA presented the Chimney Issue and the need for a Building Code amendment to The Honourable Kathleen Wynne, then the Minister of Municipal Affairs and Housing at a Planning Reform Meeting on April 20, 2012. Documents were forwarded to her Office on May 14, 2012.  The Honourable Wynne’s response on Oct 25, 2012 stated “…the issue is a complex one, whose implications go beyond the purposes of the Building Code, and affect land use planning, technical standards and common law.  However the Code Change Proposal submitted by your member associations during March 2012 was received too late to be considered for a potential next edition of the Building Code.  That being said, consultation for potential code changes may happen in future, when this proposal could be considered.”


Aaron: Amend code to protect innocent neighbours

Last week’s column told the story of the illegal chimney on a north Toronto bungalow owned by Ruta Benjamin and her husband.

When the house next door to the Benjamins’ was torn down in 2007 and a monster home erected in its place, the couple discovered that their chimney was now lower than the roofline of the new house next door and too close to it.   Suddenly their chimney became illegal.   The column brought some interesting email responses.

Bernadette Celis, communications advisor with the Technical Standards and Safety Authority (TSSA), explained why the Benjamin chimney became illegal: as a result of the construction of the new house, the chimney on their bungalow was in violation of the Natural Gas and Propane Installation Code and Ontario regulation 212/0 – Gaseous Fuels.   The code requires a fuel distributor to report to the TSSA when it finds a contravention or hazard. In this case, since the Benjamin chimney was less than two feet higher than the roof next door and less than 10 feet closer to the new house, it became a code contravention.   The code required the Benjamins to make their chimney comply at their own expense.

Was the city of Toronto wrong in issuing a permit, which resulted in a code violation against the house next door? Ray Hewlett, a retired chief building official, emailed to say that the Ontario Building Code applies to this situation.

He directed my attention to Section 8(2) of the Ontario Building Code Act, which states that if an application is properly submitted, a chief building official shall issue a permit to construct a building unless the proposed building…will contravene this Act, the building code or any other applicable law.   To my dismay, I discovered that the city of Toronto acted according to legal precedent when it issued a permit for the new house. That was the permit that caused the Benjamin chimney to be in breach of the fuel installation code.

Prior to his retirement some years ago, Pille Hansen was the chief building official of the former city of York. He emailed me to say that it was his policy to inspect properties for problems relating to chimney clearance in connection with building permit applications.   He referred me to a court case in 1995 about a property on Snider Ave. owned by Peter Alaimo. As chief building official in the city of York, Hansen had refused Alaimo a building permit due to the proximity of the chimney on an adjacent property.   Alaimo appealed to the Building Code Commission, which ruled that the building code requirement that a new permit cannot create a contravention of the act only applies to a contravention on the site under consideration, and not a property next door.   The city of York appealed the Commission decision to the Ontario Court of Justice, and lost. Justice Dennis Lane ruled that Hansen, as chief building official, could not refuse to issue a permit simply because it would create a hazard or violation with respect to the functioning of the neighbour’s chimney.   The judge wrote that the provisions of the Building Code do not regulate adjacent buildings and ordered York to issue Alaimo a building permit.

If Lane’s decision is correct in law (and I have my doubts), then there is an urgent need for Queen’s Park to amend the Building Code Act to prevent innocent neighbours like the Benjamins from being placed in an unsafe and dangerous condition a result of construction on neighbouring properties.
