OMB Records at Archives of Ontario
The Archives of Ontario holds the records from hearings
of the Ontario Municipal Board (OMB), dating from the Board’s
formation in 1906 to 1985. For more recent OMB records,
please contact the Ontario Municipal Board, 655 Bay St.,
Toronto, Ontario, M5G 1E5, 416-326-6800.

Background on the Ontario Municipal Board
Originally named the Ontario Railway and Municipal Board
it became the Ontario Municipal Board in 1932 and is the
oldest continuing quasi-judicial body in the province of
Ontario. The Board hears applications and appeals on municipal
and planning matters such as zoning by-laws, subdivision
plans, property assessments, exemptions from property taxation,
land compensation matters, and applications for municipal
annexations or amalgamations.
Over its long history the OMB performed many different
functions, reflecting the changing requirements of Ontario
municipalities and the provincial government.
- As a general rule, the earliest records of the Board
were concerned with intra and inter-municipal transportation
and communications.
- By the 1930s, the issue of municipal finance became
the predominant concern, while in the 1940s the focus
became land use planning.
- The early 1980s saw a sharp increase in the number of
appeals relating to local assessments. There was also
a drop in the number of both by-law and capital expenditure
approvals reflecting changes in the rules governing how
and why issues were brought before the Board.
The table in Appendix A
gives a chronological overview of the types of cases heard
by the OMB since its inception in 1906.
OMB Application and Appeal Process
Issues heard by the OMB follow a standard process:
- An individual, corporate body or municipality submits
an application or appeal to the Board.
- The Board assigns a case number. Case number and basic
information on the case are recorded in the Procedure
Book (Series RG 37-2).
- At the same time, an application and appeal file is
opened and labelled with the case number and a descriptive
title (see Application and Appeal
files, Series RG 37-6).
- Following the hearings, the Board could issue a Decision
(see Decision Books, Series
RG 37-5).
- Final disposition of the case is recorded in an Order
(see Order Books, Series RG 37-4).
For information on the OMB's current rules of procedure,
consult their website at www.omb.gov.on.ca.

How to Find OMB Records
Most researchers know either the municipality or the parties
involved in a specific appeal or application. Start with
the Procedure Books, which act as an index to the more detailed
case records.
If you already know the alpha-numeric code for a specific
file (eg. D9740, R83-2356), proceed to the section on Application
and Appeal files.

Procedure Books, Series RG 37-2, 1906-1985
The Procedure Books serve as the basic
index to the hearings and records of the OMB. Procedure
Books record details on the nature of the case and its final
disposition, and provide a reference, where appropriate,
to the location of orders or decisions (eg. OB1 F 300 or
DB1 F 250 or OD3 F11) issued by the Board. They are also
the primary source to identify a particular case number
to access the case files.
A complete listing of Procedure Books in the custody of
the Archives of Ontario can be found in the description
for Series
RG 37-2 in the Archives Descriptive Database (ADD)
available at www.archives.gov.on.ca. There is a brief description
of the type of cases recorded in the Procedure Books, and
instructions on how to order the books.
Over the years, the Procedure Books were organized differently.
The following table will help researchers understand what
they will find in the Procedure Books.
| Hearing Year |
How to use the Procedure Book as an index |
| 1906-1952 |
The entries in the procedure books were in simple
numeric sequence by the case number. To link these
entries with specific applications you must first
consult the indexes found in Series
RG 37-3, Ontario Municipal Board Indexes to Procedure
Books. |
| 1952-1956 |
The Procedure Books themselves became the alphabetical
index to case references. Up until 1956, cases were
organized by the name of the individual or corporate
body responsible for instigating the application,
whether a person, company, municipality or Government
of Ontario department. If you have difficulty locating
a hearing, try searching under the name of a government
department, particularly the Department of Highways,
the Department of Planning and Development, the Department
of Municipal Affairs or the Hydro Electric Power Commission. |
| 1956-1972 |
The indexing was simplified so that all cases were
identified in the Procedure Books by the name of the
municipality to which the application referred. The
Procedure Books were also identified by the type of
case involved. In each year there would be a range
of volumes for capital expenditures and a second range
of volumes for all other types of application and
appeals. |
| After 1972 |
The growing complexity of the case load saw a further
expansion in the types of procedure books employed.
The list of Procedure
Books provides an overview of the different
indexing approaches used. In every case, the cases
are arranged alphabetically by the municipality and
then in chronological order of filing with the Board. |
Once you have found a relevant entry in the Procedure Book,
you can refer to the File Classification Table in the RG
37-6-1 description in the ADD (scroll down
to "Finding Aid" and click to view the online
finding aid) to confirm that the file number identified
corresponds to the type of case you were interested in.
If so, read on to determine which type of record will provide
the information you require.

Order Books, Series RG 37-4, 1906-1985
The Procedure Books provide a reference for the orders
issued by the Board in deciding a case. The information
is provided in the format of an OB (Order Book) volume number,
and folio (page) number (eg. OB1 folio 300).
The Orders issued by the Board are useful in establishing
the basic outcome of a case heard by the OMB. Generally
they do not record detailed information but they do indicate
the final disposition of the case. The Orders are regarded
as the key legal documents in resolving any disputes arising
from the disposition of a case.
A complete listing of Order Books in the
custody of the Archives of Ontario, as well as instructions
on how to order the books is found in the description for
Series
RG 37-4 in the Archives Descriptive Database,
available at www.archives.gov.on.ca.

Decision Books, Series RG 37-5, 1957-1985
The Procedure Books also refer to Decision Books (eg DB1;
DB62). The decisions themselves are arranged within these
volumes in chronological order by date of issue.
Only a minority of cases heard by the OMB result in a written
decision. If a particular case was non-controversial, did
not involve complicated evidence or include other complicating
factors, the Board only issued an Order. Decisions were
reserved for instances where there were significant issues
at dispute or where there might be some disagreement regarding
the relevance of the evidence submitted to the hearing.
In some instances, the Board issued an Oral Decision, a
memorandum of which can be found in the corresponding Application
and Appeal files. After 1984 the Board began issuing separate
Oral Decision Books, which again provide a reference to
volume number, and folio number (eg. OD3 F11).
The text of the decisions, which can vary greatly in length,
provide much more information on the decision-making process.
Decisions can be used by the Commission to explain their
reasoning, to call into question particular evidence or
to explain why a particular application lacked merit under
the relevant statutes or regulations. Frequently, decisions
are used in conjunction with relevant orders during any
re-hearings or to determine case precedents.
A complete listing of Decision Books in the custody of
the Archives of Ontario, as well as instructions on how
to order the books can be found in the description for Series
RG 37-5 in the Archives Descriptive Database,
available at www.archives.gov.on.ca.
Application and Appeal files, Series RG 37-6, 1925-1984
Application and Appeal files contain the basic documentation
generated in the course of a hearing, including: the original
application and supporting documents, responses and objections
from interested parties and material related to the scheduling
of hearings. The files generally include photocopies of
any Orders and Decisions as well.
Please be aware that the case files for the OMB have several
gaps:
| 1906-1925 |
All case files were destroyed by the
Commission sometime prior to 1950. |
| 1925-1949 |
The Board destroyed all files relating to capital
expenditures and municipal finance. The bulk of the
surviving records from this period relate to by-laws,
lot plans, subdivisions and municipal organization. |
| 1954 |
All files relating to the approval of telephone
service applications were transferred to the newly
formed Ontario Telephone Authority. These records
can be accessed through Series RG
14-42, Telephone Act approvals order files. |
Applications and Appeals files are described in 6 sub-series
in the Archives Descriptive Database, (ADD) available at
www.archives.gov.on.ca. The bulk of the surviving case files
for the OMB are in sub-series RG
37-6-1. The other 5 sub-series are records
of significant cases (Spadina Expressway, the formation
of Metropolitan Toronto) which were removed from the main
run of case files and whose integration back into the main
filing system was not practical.
Case file numbers can be obtained by doing a keyword search
of the ADD Files and Items search option or by referring
to Procedure Books as described above. If you already know
the case file number (eg. D9740, R83-2356) simply submit
a Records Request Slip for RG
37-6-1, Application and Appeals files.
The case file number indicates the year and type of case
heard; however because the OMB’s file classification
scheme changed over the years, an explanatory table is available
with the ADD description to series RG 37-6-1.

Definitions:
This section provides definitions for terms that appear
frequently in the documentation of the OMB.
Committee of Adjustment:
This is a planning committee established at the level of
a township, town, village, city or county/region to review
applications for a "minor variance" (defined below).
Decisions by Committees of Adjustment may be appealed to
the Ontario Municipal Board.
Consents to Convey Land:
Under the Planning Act the Minister of Municipal Affairs
and Housing has the authority to issue orders relating to
the subdivision of lands for areas that have not yet established
a Land Division Committee. These orders may be appealed
to the Ontario Municipal Board.
Development Charges:
Municipalities are allowed to levy development charges on
new subdivisions or other projects to help pay for the provision
of services, such as schools and water/sewage facilities,
to the new development.
Land Division Committee:
This is a planning committee established at the level of
a separated city, county or region to review applications
for land severances restricted under local zoning and other
land use controls. Decisions by Land Division Committees
may be appealed to the Ontario Municipal Board.
Legal non-conforming use:
Zoning by-laws can prohibit a particular land use in specific
areas; however these prohibitions do not apply to existing
businesses operating in the area. A pre-existing business
of a prohibited type within the area of land use control
is referred to as a legal non-conforming use.
Local improvement:
Local improvements refer to capital expenditures for new
or renovated facilities such as roads, sidewalks, water
and sewage works. OMB approval is generally required for
expenditures on these types of projects.
Local Planning Board:
Local Planning Boards are established at the municipal level
to examine proposals for zoning by-laws, official plans,
amendments and other planning instruments. The Boards make
recommendations to municipal councils regarding the feasibility
or desirability of proposals. In many municipalities, specific
planning matters that have received general approval through
zoning by-laws or official plans may be approved by the
Local Planning Board. Local Planning Board decisions may
be appealed to the OMB.
Minister's Zoning Orders:
Under the Planning Act, the Minister of Municipal Affairs
and Housing can issue temporary zoning orders to control
land uses in municipalities that have not yet established
comprehensive land use plans. These orders may be appealed
to the Ontario Municipal Board.
Minor variance:
All municipalities are required to have zoning by-laws controlling
matters such as densities, lot frontage, free space between
buildings. Property owners can apply to the municipal government
for a permit which recognizes that a proposed change to
their property is a minor variance of the zoning by-law
and not a violation of its intent. If the application is
rejected, the applicant may appeal to the Ontario Municipal
Board; if the application is accepted neighbours who object
to the plan may appeal to the OMB.
Municipal organization:
The OMB hears cases involving the structure and boundaries
of municipalities including ward divisions, annexations,
amalgamations, development charges, development plans, and
road closings.
Official Plan:
Under the Planning Act, all municipalities must prepare
an Official Plan to establish overall land use planning
regulations for the area. These plans are approved by the
Minister of Municipal Affairs and Housing. Individuals,
corporations, and lower tier municipalities may object to
the plan through the Ontario Municipal Board. If a proposed
plan is particularly complicated or contentious, the Ministry
of Municipal Affairs and Housing often submits it to the
OMB. Amendments to existing Official Plans are generally
referred to the OMB for review.
Planning Area:
The Planning Act permits the creation of planning areas
that extend beyond municipal boundaries. The objective is
to ensure consistent planning decisions among municipalities
which share common interests. Planning areas can range in
size from two adjoining townships to the level of a region
or county.
Quieting orders:
Many township municipalities established under the general
terms of the 1850 Baldwin Act were never named as municipalities
in any specific by-law or legislation. Quieting orders were
issued by the Ontario Municipal Board to confirm the boundaries
and status of these municipal corporations. Most quieting
orders were issued in the 1950s and 1960s.
Redevelopment Plans:
Municipalities create redevelopment plans to promote improvements
in downtown core areas, industrial lands or other under-utilized
areas. Ontario Municipal Board approval is required for
any capital expenditures or zoning changes that arise from
the redevelopment plan.
Restricted area by-law:
A restricted area by-law is an instrument used by municipalities
to expand on the general provisions contained in the Official
Plan for the area. The municipality applies the intent of
the official plan to a particular “restricted area”
of the municipality. Generally, a restricted area by-law
is used to augment controls over expansion of commercial
and industrial operations into agricultural or residential
areas. Until 1983 OMB approval was required for all restricted
area by-laws. After 1983, the Board only heard appeals initiated
by residents or businesses affected by the by-law.
Severances:
Severances relate to the sub-division of lots. Land Division
Committees decide on most severances; however disputes relating
to farm lots or large rural estates that the owners wish
to subdivide for family use on retirement often come before
the Ontario Municipal Board.
