Thank you.
Good, sunny afternoon, Mr. Chair and committee members.
I'm Deborah Carlson, I'm a staff lawyer at West Coast Environmental Law. We're a not-for-profit public interest environmental law reform organization based in Vancouver, B.C., on the Coast Salish territories of the Squamish, Musqueam and Tsleil-Waututh nations. Thank you very much for the invitation to appear. I'm grateful to be here today, on the territory of the Algonquin Anishinabe people, to play a small part in this very important work you're doing here today and on other days.
My focus today is on the habitat protection provisions of the Fisheries Act. Across our country right now, I think it's fair to say, we're grappling with economic challenges that are not fully within our control, but in these times I put to you that it's more important than ever for us to take care of our own house and to do a good job managing the things that we do control. Healthy lands and waters are the foundations of well-being and resilience for communities across our country, including economic well-being and resilience. In this context, fish habitat protection remains a critical responsibility for the Department of Fisheries and Oceans.
In 2019, lawmakers amended the purpose of the Fisheries Act to emphasize the mandate for conservation and protection of fish habitat, but today, I'd like to draw your attention to a particular aspect of habitat protection mandated by the act, of which implementation has been less than satisfactory, in my view. In 2019, lawmakers added specific factors to section 34 that the minister must consider in relation to fish habitat protection, to make sure these were taken into account. One of these factors is cumulative effects. The minister must consider cumulative effects in decision-making and in making regulations.
I expect you're familiar with the issue of cumulative effects: essentially, many small impacts that add up and combine to produce large impacts. It's often called “death by a thousand cuts”, but today I want to give you another analogy that I think helps understand how this problem creeps up on us. Think of a small leak, maybe behind a wall, that goes on for a long time, unnoticed. Each drop isn't significant, but over time, quietly, the drops can add up to some massive damage. This, essentially, is the problem of cumulative effects in relation to fish habitat: They do accumulate in the same way—slowly—so they might not even be noticed until a critical threshold is passed.
Back in 2008, renowned expert Dr. Charles Minns tried to draw attention to the habitat losses associated with smaller projects, saying that, across the country, “The aggregate impact of many small projects likely matches the impact of the fewer large projects.”
DFO scientists and science advisory panels are certainly well aware of this problem and have done extensive analysis and research, yet despite the legal requirement that has been in the act since 2019, the only public evidence of DFO work to consider cumulative effects in law and policy is the 2025 position statement. This is about a subset of decision-making for authorizations for individual projects. It's hard to say how it is applied in practice, because it's based on how, decision by decision, you would actually consider cumulative effects. There's no reference point. When are the cumulative effects considered to be too great? However, there's a further missing piece with respect to the implementation. The minister is also directed to consider cumulative effects when making regulations. I see no evidence that this has been done and no framework for doing so.
There are also multiple studies by external researchers documenting that DFO policies and procedures related to such things as offsetting, self-assessment of risk by proponents and DFO letters of advice have had enough slippage in them—small impacts—to make significant contributions to cumulative effects.
In light of this somewhat unscrutinized and, I argue, unmanaged problem of critical effects related to the implementation of DFO regulations and policies, I suggest you make the following recommendations as part of your review. The two first are related. The first recommendation is that DFO be asked to develop a tool to assess and manage the risk of cumulative effects harmful to fish habitat associated with new or updated regulations, with transparent reporting. The second recommendation is to do the same thing with respect to DFO policies and procedures governing authorizations and other directions to project proponents. Finally, the third recommendation is that DFO be asked to report back to the committee, within one year, on its progress in implementing these first two recommendations. These are steps towards fulfilling the legal direction provided by the act and getting DFO on a path to understanding and managing the cumulative effects associated with its own regulations and policies.
Thank you.
