The client
A couple self-building on a wooded rural lot near Greater Sudbury, financing the build through a construction-to-permanent mortgage. A pre-construction ecological walk-through, ordered ahead of site alteration, flagged likely habitat for a species on the Protected Species in Ontario list along the lot's rear tree line.

The problem
As recently as early 2026, a finding like this would have run through Ontario's Endangered Species Act, 2007 -- an MNRF permit application under section 17, reviewed and issued before site alteration could proceed. That Act no longer exists. On March 30, 2026, the Species Conservation Act, 2025 came into force and repealed it outright.
What actually governs a habitat finding now
- ▸The Species Conservation Act, 2025 is administered by the Ministry of the Environment, Conservation and Parks (MECP), not the Ministry of Natural Resources and Forestry that ran the old Act
- ▸It runs on a 'registration-first' model: many activities that would have needed a permit and a government review can now proceed once registered on the province's Species Conservation Registry
- ▸Before a registrable activity can be registered, a qualified professional must first develop a conservation plan for it -- that step is a precondition to registering, not optional paperwork filed alongside it
- ▸Higher-risk activities still require a formal permit rather than registration; a site-specific ecological evaluation is what determines which pathway applies
The lot's ecological evaluation confirmed the activity as registrable rather than requiring a full permit -- a faster outcome than the old regime would have produced. But 'faster' still meant a qualified professional had to complete a conservation plan, and the couple had to register the graded site alteration on the provincial registry, before the excavator could touch the rear tree line -- a step that ran on its own timeline, independent of the municipal building permit the county had already issued.
The numbers
This is an insured construction-to-permanent mortgage. The registration step didn't change the mortgage math -- it changed when the site-prep draw could be requested.
| The build | Amount |
|---|---|
| Appraised value on completion | $520,000 |
| Down payment (10%) | $52,000 |
| Base mortgage before premium | $468,000 |
| CMHC premium (90% LTV, 3.10% band) | $14,508 |
| Insured mortgage | $482,508 |
Old regime vs. current regime
| Before March 30, 2026 | From March 30, 2026 |
|---|---|
| Endangered Species Act, 2007 | Species Conservation Act, 2025 |
| MNRF permit under §17, government-reviewed | Qualified-professional conservation plan, then registration on the Species Conservation Registry |
| Ministry: Natural Resources and Forestry | Ministry: Environment, Conservation and Parks |
Sizing and ratios
| Mortgage math | Figure |
|---|---|
| Minimum qualifying rate — greater of contract + 2% and 5.25% | 7.49% |
| Monthly payment at the qualifying rate | $3,527 |
| Monthly payment at the 5.49% contract rate | $2,942 |
| GDS (qualifying payment + $300 tax + $150 heat) ÷ income | 37.9% |
| TDS (housing + $220 other debt) ÷ income | 40.0% |
The solution
The broker treated the province's repeal of the old Act as a live fact to verify, not something to assume still applied because it had governed every prior habitat file. Confirming the current regime directly with the qualified professional avoided budgeting for an MNRF permit process that no longer exists.
Once the conservation plan was in hand, registering the activity took a matter of days rather than the weeks a permit application under the old Act would have needed -- the real lead time was the qualified professional's assessment and plan, not a government queue.
The outcome
The mortgage funded at $482,508, 90% LTV, on a five-year fixed at 5.49%, qualifying payment $3,527, GDS 37.9% and TDS 40.0%. The conservation plan and registration were both in place twelve days after the ecological evaluation flagged the habitat, and grading began on schedule with the county's building permit already issued -- one file in a residential construction sector where new-regime habitat questions are only going to come up more often.
What to take from this file
- 01Ontario's Endangered Species Act, 2007 is gone -- repealed and replaced by the Species Conservation Act, 2025 on March 30, 2026. A file that still budgets for an MNRF permit under the old section 17 is planning around a statute that no longer exists.
- 02The new Act is 'registration-first,' not permit-free. A qualified professional's conservation plan is still a real precondition, even where a full permit isn't required.
- 03MECP administers the current Act; MNRF administered the old one. Confirm which ministry and which process actually applies before advising a client on timeline.
- 04A provincial habitat process runs independently of the municipal building permit. Passing one doesn't substitute for the other, whichever regime is current.
