HOW TO USE THIS BY-LAW
Sections 1-10: Land use areas and zones
Sections 1 to 10 describe distinct land use areas of the City. Lands within the same land use area have a
similar built form and/or function in the community.
Each land use area section has three subsections. Each subsection is identified with an icon.
1. Permitted uses and density standards
The first subsection describes one or more zones. These zones permit specific
uses and establish density standards on all properties within the land use area.
Every property in the City is located within a zone listed in this By-law. You can
determine what zone applies to a property by locating it on the Zoning By-law map.
The official Zoning By-law maps are attached to this By-law as Schedule A. An
interactive zoning map is also available online.
To find out which zone applies to a property, go to the interactive zoning map and type in its address. If you
don't know the address, search for a nearby landmark or search by manually moving the map.
Each zone has a unique list of permitted uses. Only uses described in that list are permitted on lands
designated as that zone. Zones have standards that control density such as lot size, lot coverage, and
limits on the number of uses or buildings that also apply.
2. Height and location requirements
The second subsection regulates the height and location for buildings, structures,
and land uses such as outdoor storage. It includes minimum and maximum
heights, setbacks, and separation distances for all buildings or structures in that
land use area. This subsection applies to all zones described in the first subsection.
3. Access, landscaping, and parking requirements
The third subsection regulates access, landscaping, and parking, such as maximum
driveway widths or minimum number of required parking spaces, in that land use
area. This subsection applies to all zones described in the first subsection.
Section 11: Site development standards
This section sets out the standards for site features such as landscaping and parking. This section
includes details such as how large a parking space must be or how many accessible parking spaces need
to be provided on a lot. These are important regulations that apply to all sites in every zone. Zoning By-laws
traditionally refer to these standards as "general regulations".
ii | CITY OF THUNDER BAY ZONING BY-LAW
Sections 12-13: Use or areas specific regulations
These sections only apply to specific uses, areas, or sites. Section 12 describes regulations for specific land
uses such as backyard homes. The regulations apply to those uses regardless of what zone they are in.
Section 13 regulates areas with special development constraints such as height restrictions or private
servicing (i.e. private wells and septic systems).
Lands identified by the environmental overlay or zoned EP - Environmental Protection are subject to the
Lakehead Region Conservation Authority's (LRCA) permit system. A permit from the LRCA is required
for most forms of development or site alteration in these areas. The environmental overlay is shown as
grey shading on the Zoning By-law map attached as Schedule A. The environmental overlay can also be
viewed using the interactive zoning map. Refer to Section 16.15.2 of this By-law for rules relating to the
interpretation of the environmental overlay.
Sections 14-17: Definitions and legal details
These sections define specific terms and detail how the By-law is interpreted and enforced.
Wherever a term in this By-law is in bold letters, the term has a defined meaning set out for it in Section
15. Wherever a term is in regular font, its typical English language definition applies.
Schedules A, B, and C
Schedule A is the map which identifies how properties in the City are zoned. These are available in an
interactive online format.
If the zone label is followed by an 'H' suffix, that area of land is affected by a holding provision. The
number after the 'H' symbol on the zone label corresponds to specific holding provision. Consult
Schedule B to determine what is included in the corresponding provision.
If the zone label is followed by an SP' suffix, that area of land is affected by a site-specific provision. The
number after the 'SP' symbol on the zone label corresponds to a site-specific zoning provision. Consult
Schedule C to determine what is included in the corresponding provision.

16.14 Reference to land use area
Sections 1 through 10 comprise different land use areas that include one or more zones. A reference made to a land
use area includes all zones within that land use area.
16.15 Zone schedules
16.15.1 Zones
The location, extent, and boundaries of all zones are shown on Schedule "A".
16.15.2 Environmental overlay
The location, extent, and boundaries of the environmental overlay are shown on Schedule "A" with a shading over
top of the underlying zones.
a. The Corporation acknowledges that areas adjacent to floodplains, wetlands, talus slopes, and watercourses in
Thunder Bay are under the jurisdiction of the Lakehead Region Conservation Authority (LRCA). The Corporation
further acknowledges that the LRCA has the authority to regulate and/or prohibit development within these ar
eas. Finally, the Corporation acknowledges that mapping lines associated with these features can change based
on soil erosion, new data or study results, or other factors. To alert readers of this By-law to the fact that, where
development occurs in these areas, there will be requirements of the LRCA in addition to those imposed by this
By-law, the Corporation has applied the environmental overlay to the maps.
b. The environmental overlay consists of shaded areas of land under the jurisdiction of the LRCA. The environmen
tal overlay is not considered to be an integral part of this By-law. Accordingly, changes in mapping associated
with these areas can result in changes to the environmental overlay without formal amendment being required
to this By-law. Readers of this By-law are directed to consult with the LRCA whenever they are considering
development on land that is near any of these features, whether or not it is contained within the environmental
overlay on any map that forms a part of this By-law.

followed by the letters "SP" and a number in parentheses in superscript.

16.16 Limits of zones
When determining the boundary of any zone as shown on Schedule "A", the following applies:
a. A boundary indicated as following a street, lane, railway right-of-way, utility corridor, or watercourse will be the
centre-line of the applicable feature and the applicable feature must be included within the zone of the adjoining
lot(s) on the sides thereof.
b. A boundary indicated as following lot lines on the effective date of this By-law or the municipal boundaries of the
City must follow such lot lines or boundary.
c. Where any zone boundary is not shown to be a street, lane, right-of-way, or watercourse, and where the bound
ary approximately follows the limit of a lot (as of the date of the passage of the by-law that applied the boundary),
the zone boundary is considered to be the lot boundary.
d. The closure of a street, lane, or right-of-way that formed a zone boundary under Section 16.16 a) does not consti
tute an amendment to the zone boundary. Accordingly, if a street, lane, or right-of-way that formed a zone bound
ary is closed, the zone boundary is considered to be the centre line of the former street, lane, or right-of-way.
e. Where any zone boundary is left uncertain after the application of the provisions of this Section, the boundary will
be determined by the Corporation's Director of Planning Services by scale. Where a measurement falls with
in a zone boundary line on any map, the measurement must be taken to be the middle of the width of the zone
boundary line as shown on the relevant map.
f. Where the Holding zone boundary is located on a lot, it is deemed to be a lot line for the purposes of this By-law.
