Exception Zones and Exception Zone Schedules
1.1.2.3.1
An Exception Zone is expressed as a hyphenated numeric suffix to a Base Zone, such as
"RL-22" or "G2-4(1)". An Exception Zone is a Base Zone that has been modified by
adding or deleting one or more permitted uses and/or regulations. The uses and/or
regulations stipulated in an Exception Zone take precedence. The Base Zone Provisions,
Zone Category General Provisions, General Zone Provisions and/or Definitions shall
apply to all buildings and structures and the use of a subject property unless otherwise
stated. (0325-2008), (0048-2025)
1.1.2.3.2
An Exception Zone Schedule, where used, contains details such as the boundaries of the
subject property, building envelopes, required setbacks and height limitations, amongst
other regulations. The provisions of an Exception Zone Schedule take precedence over
the provisions of the Exception Zone, Base Zone Provisions, Zone Category General
Provisions, General Zone Provisions and/or Definitions unless otherwise stated. Where
dimensions are not indicated on an Exception Zone Schedule, the regulations of the
Exception Zone, Base Zone Provisions, Zone Category General Provisions, General Zone
Provisions and/or Definitions shall apply. (0379-2009)
1.1.2.3.3
Notwithstanding the regulations contained in an Exception Zone and Exception Zone
Schedule, a maximum of two attached ARUs, or a maximum of one attached ARU and
one detached ARU are permitted per lot, and Subsection 4.1.1 of this By-law shall apply.

H-RL-86), the lands to which it refers on the Zoning Maps (Schedule B of Part 13 of this
By-law) shall be subject to a holding provision. Lands with a holding provision shall only
be used for a use legally existing on the date of passing of this By-law. The erection of
new buildings or structures and the enlargement or replacement of existing buildings
and structures shall not be permitted. In order to remove the holding provision, the
Commissioner of Planning and Building, delegated authority by Council, must approve
the removal of the "H" holding provision which is done when conditions specified in the
By-law implementing the holding provision have been met. A By-law is signed by the
Mayor and City Clerk. (0048-2025)
1.1.3
Reduction of Lot Area
No reduction of a lot in area, either by the conveyance or alienation of any portion thereof
or otherwise, is permitted so that the area covered by buildings or structures on the lot
exceeds the maximum permitted by this By-law and the yards provided are less than the
minimum permitted by this By-law for the zone in which the lot is situated.
1.1.4
More Than One Zone
1.1.4.1
When a lot is divided into more than one zone, each portion of the lot shall comply with
the applicable provisions of the zone in which it is situated. Required
yards/setbacks/buffers shall be measured from the zone boundary. (0325-2008)
1.1.4.2
Where a building or structure is constructed across two or more zones, the use of the
building or structure must be permitted in all the zones and the required
yards/setbacks/buffers along the common zone line(s) shall not apply. (0325-2008)
1.1.5
Measurement of Setbacks
1.1.5.1
Where the regulations of a zone include a requirement for a setback to a lot line, the
setback requirement shall be measured as indicated in the regulation.
1.1.5.2

the term "street" is interchangeable with the term "public highway right-of-way" and
both terms are interchangeable with other terms for identifying public highway rights-of-
way including proper names.
1.1.6
Measurement of Yards
1.1.6.1
Where the regulations of a zone include a requirement for a yard to be of a minimum
size, the yard requirement shall be measured from the lot line abutting the yard to the
nearest part of any building or structure on the lot. (0325-2008)
