New substances: chemicals and polymers waivers

Waivers of Information Requirements

Overview

Under subsection 81(8) and 106(8) of the Canadian Environmental Protection Act, 1999 (CEPA), Canadian importers, manufacturers or users of Substances may request "waivers" for any of the prescribed information under subsection 81(1), (3) or (4) or 106(1), (3) or (4) if certain conditions are met.

The decision to grant a waiver is made on a case-by-case basis by Environment and Climate Change Canada. On average, approximately 100 waivers are granted yearly for an average of 500 notifications received.

The statutory criteria for a waiver of information requirements that are identified in subsection 81(8) or 106(8) of CEPA are:

  1. in the opinion of the Ministers, the information is not needed in order to determine whether the substance or the living organism is toxic or capable of becoming toxic;
  2. a substance or living organism is to be used for a prescribed purpose or manufactured at a location where, in the opinion of the Ministers, the notifier requesting the waiver is able to contain the substance so as to satisfactorily protect the environment and human life; or
  3. it is not, in the opinion of the Ministers, practicable or feasible to obtain the test data necessary to generate the information.

Statistics of the waiver of information requirements granted per year

In 2016, a total of 109 waivers were granted for chemicals and polymers under subsection 81(8) of CEPA, and 14 waivers were granted for organisms under subsection 106(8) of CEPA.

In 2015, a total of 109 waivers were granted for chemicals and polymers under subsection 81(8) of CEPA, and 26 waivers were granted for organisms under subsection 106(8) of CEPA.

In 2014, a total of 94 waivers were granted for chemicals and polymers under subsection 81(8) of CEPA, and 18 waivers were granted for organisms under subsection 106(8) of CEPA.

In 2013, a total of 94 waivers were granted for chemicals and polymers under subsection 81(8) of CEPA, and 13 waivers were granted for organisms under subsection 106(8) of CEPA. Only one waiver was rejected for chemicals and polymers.

Examples of common rationale for granting waivers

Waivers may be granted for a variety of reasons depending on the substance or the living organism notified.

Some of the most common reasons for granting a waiver under paragraph 81(8)(a) or 106(8)(a) of CEPA are:

  • The substance is highly volatile.
  • The substance is a salt and changes to a different substance in water.
  • The substance decomposes or reacts dangerously during the performance of the test.
  • The substance cannot dissolve in any solvent suitable for use in an analytical method.
  • The substance has no readily hydrolysable groups and therefore is not expected to hydrolyze.
  • The living organism is known not to cause human health effects.

Some of the most common reasons for granting a waiver under paragraph 81(8)(c) or 106(8)(c) of CEPA are:

  • The substance is unstable in the purified form.
  • The substance reacts dangerously with water.
  • The substance is a salt and changes to a different substance in water.
  • The substance decomposes or reacts dangerously during the performance of the test.
  • The substance cannot dissolve in any solvent suitable for use in an analytical method.
  • The substance is explosive or reacts dangerously in the presence of light.

Waivers may also be granted under paragraph 81(8)(b) or 106(8)(b) of CEPA when it is demonstrated that the substance or living organism is to be manufactured at a location where it is contained so as to satisfactorily protect the environment and human life.
