Applied to intrusive work
Environmental diligence in Yukon is a Yukon Department of Environment matter, not a municipal one. The Environment Act — specifically Contaminated Sites Regulation, O.I.C. 2002/171 — sets what has to be investigated, who is competent to sign the report, and what has to be filed before a site is considered closed out. That is why cost and calendar move at the Yukon line and barely at all between Whitehorse: a consultant charges roughly the same to drill in either, but the filing route, the standards the lab reports against, and the regulator's review time are identical province-wide.
What forces intrusive work here is specific. Registry listing or a known release triggers investigation. Mobilisation, not regulation, sets the schedule: crews and labs are southern. A buyer who reads that as discretionary tends to discover otherwise in the last week of the condition period, when the Phase I recommendation lands and the only remaining moves are an extension request or a waiver of the very condition that was protecting them.
The Envirolor reference scope for Yukon — a 50,000 sf industrial building, lender-financed, with no flagged site history — models at $15,400–$60,900 and a 30-day critical path from engagement to a reviewed set of drafts. Add a confirmed area of potential environmental concern and both numbers move sharply: the Phase II is the only report in the sequence that cannot start until the Phase I finishes, so it adds its full duration to the calendar rather than running alongside anything.
Schedule, not fee, is the binding constraint in Yukon. Drill crews, lab couriers and even the reviewing professional are usually mobilised from outside the territory, and Envirolor carries a 14-day scheduling penalty on intrusive work here for exactly that reason. A condition period written to a southern template will not survive contact with a barge window or a freeze-up.
Envirolor does not perform assessments and takes no fee from consultants. The figures on this page are modelled from published cost bands scaled by area, regional index and risk, so they are a budgeting and sequencing instrument, not a quotation. Where a promoted observation exists for a Yukon report type, it replaces the modelled band and is labelled as observed.
Envirolor facts
- Yukon governs contaminated sites under the Environment Act — Contaminated Sites Regulation, O.I.C. 2002/171. The closing instrument is the site registry entry and certificate of compliance.
- On the Envirolor reference asset — a 50,000 sf lender-financed industrial building with no site-history flags — a clean scope in Yukon models at $15,400–$60,900 over a 30-day critical path.
- Envirolor tracks 1 Yukon market against this jurisdiction's rules, with a regional cost index of 1.40 and a 14-day scheduling penalty on intrusive work.

Scope fits
| Report | Status | Cost band | Days | Lands |
|---|---|---|---|---|
| Roof / envelopeA 41-year-old roof is usually the largest single line in the reserve table; a dedicated review turns a range into a number. | Recommended | $3,500–$15,400 | 19 | Day 19 |
| DSS / hazmatA 1985 building is pre-ban construction: the survey is legally required before any renovation or demolition is tendered, and the abatement number belongs in the purchase price. | Required | $3,900–$18,200 | 21 | Day 21 |
| Phase I ESAEvery lender on a commercial file requires a Phase I addressed to it with reliance, dated within six months of funding. | Required | $3,100–$7,700 | 22 | Day 22 |
| BCA / PCAThe lender's reserve requirement is set off the BCA's capital table, so it is a funding condition, not a nice-to-have. | Required | $4,900–$19,600 | 25 | Day 25 |
Out of scope, and why
- Phase II ESA — No area of potential environmental concern was flagged, so the Phase I should close without sampling. If it does not, add roughly the Phase II band to both cost and calendar.
- Geotech — An existing building with a known grading history rarely needs a geotech at acquisition; add one before any addition.
- Elevator — No elevating devices in the asset.

Scope of work
1. Roof and Building Envelope Review — Recommended
Roof-level inspection with core cuts where warranted, moisture scanning, flashing and parapet review, and an envelope assessment covering cladding, sealants and glazing, with remaining service life and replacement cost.
$3,500–$15,400 · engage day 0 · draft day 19
2. Designated Substance and Hazardous Materials Survey — Required
Bulk sampling and laboratory analysis for asbestos-containing materials, lead, mercury, silica and other designated substances, producing the inventory that must be handed to any contractor before demolition or renovation.
$3,900–$18,200 · engage day 0 · draft day 21
3. Phase I Environmental Site Assessment — Required
Records review (fire insurance plans, aerial photography, title, environmental registries), a site reconnaissance visit, and interviews with the owner, occupants and the municipality. The deliverable identifies areas of potential environmental concern (APECs) and states whether intrusive investigation is warranted.
$3,100–$7,700 · engage day 0 · draft day 22
4. Building Condition Assessment — Required
A walk-through of structure, envelope, roofing, mechanical, electrical, vertical transportation, life safety and site works, followed by an immediate-repair list and a capital reserve table projecting replacement costs over the study period.
$4,900–$19,600 · engage day 0 · draft day 25
Verdict
This scope runs 3 required and 1 discretionary report, for a modelled $15,400–$60,900 and a 30-day critical path from engagement to a reviewed set of drafts.
Against the 45-day condition period entered, that leaves 15 days of slack — enough to absorb one lab delay, not two.
No area of potential environmental concern was flagged, so the base case is a Phase I that closes clean. If it does not, the Phase II adds roughly 30 days and the sampling band to this answer.

05Questions
What triggers a Phase II ESA in Yukon?
Registry listing or a known release triggers investigation. Mobilisation, not regulation, sets the schedule: crews and labs are southern.
What does a Phase I ESA cost in Yukon?
On a 50,000 sf commercial building, Envirolor models a Yukon Phase I at $3,100–$7,700, with a 22-day turnaround from engagement to draft. Records requests, not fieldwork, set that clock.
How long should a condition period be for Yukon diligence?
A clean scope on the reference asset needs 30 calendar days. If the Phase I is likely to recommend sampling, plan on the Phase II adding its full duration on top, because it cannot begin until the Phase I finding exists.
Who reviews the file in Yukon?
Yukon Department of Environment. The closing instrument is the site registry entry and certificate of compliance, and the consultant signing the report must meet the qualification the Environment Act sets.
