    Frequently Asked Questions
  • Information and Management of Time Limits Regulations
    IAA requires that the proponent of a designated project submit a project description to the Impact Assessment Agency of Canada. These regulations set out the information that must be included in a project description. These regulations also include criteria under which the legislated timelines can be suspended, the guidelines and plans the Agency is required to provide to the proponent, and the format in which information should be provided to the Impact Assessment Agency of Canada.
    Frequently Asked Questions
  • Cost Recovery Regulations
    CEAA 2012 provides for cost recovery to enable the Canadian Environmental Assessment Agency to recover from the proponent of a project certain costs incurred during the course of an environmental assessment. These regulations set out the services and amounts for which the Agency can recover costs from the proponent of a project that undergoes an assessment by review panel. When the IAA comes into force, the Cost Recovery Regulations under CEAA 2012 will continue to apply until such time as new Cost Recovery Regulations are developed under the IAA.

Transitional environmental assessments

When the IAA came into force, the former Canadian Environmental Assessment Act, 2012 (CEAA 2012) was repealed. The IAA includes transitional provisions for environmental assessments that were underway at that time.

Any screening of a project commenced under the former Canadian Environmental Assessment Act of 1992 (the 1992 Act), in respect of which the responsible authority has not , before the day on which the IAA came into force, taken a course of action under section 20 of the 1992 Act, was terminated.

Any comprehensive study of a project commenced under the 1992 Act in respect of which the Canadian Environmental Assessment Agency (former Agency) has not, before the day on which the IAA came into force, published a notice under subsection 22(1) of the 1992 Act, was terminated.

Any comprehensive study of a project commenced under the 1992 Act, in respect of which the former Agency has, before the day on which the IAA came into force, published a notice under subsection 22(1) of the 1992 Act, is continued as an environmental assessment by the Agency under CEAA 2012 as if CEAA 2012 had not been repealed.

Any comprehensive study of a project that was the subject of an order made by the Minister under subsection 125(7) of CEAA 2012 before the day on which the IAA came into force is continued as an environmental assessment under CEAA 2012 as if that Act had not been repealed.

If a proponent of a designated project under CEAA, 2012 submitted a project description to former Agency and the former Agency has not posted a notice under subsection 8(1) of CEAA 2012, the screening is terminated. The description of the designated project that was provided under subsection 8(1) of CEAA 2012 is deemed to be an initial description of the project provided under subsection 10(1) of the IAA on the day that act came into force.

Any environmental assessment of a designated project commenced under CEAA 2012 by the former Agency, in respect of which the former Agency has posted the notice of commencement under section 17 of CEAA 2012 before the day on which the IAA came into force, is continued under CEAA, 2012 as if that act had not been repealed.

Any environmental assessment of a designated project by the National Energy Board commenced under CEAA, 2012, in respect of which a decision statement has not been issued under section 31 of CEAA, 2012 before the day on which the IAA came into force, is continued under CEAA, 2012 as if that act had not been repealed.
