How long does a Phase 2 ESA take in Oshawa?
Three to six weeks is typical, depending on site access for drilling and how long lab results take.
How much does a Phase 2 ESA cost in Oshawa?
Cost is driven by the number of sample locations, lab work required, and site access, priced to a defined scope before work begins.
Which standard applies?
Transactions and due diligence typically use CSA Z769; O. Reg. 153/04 is required where a Record of Site Condition or permit is involved.
Does a Phase 2 always follow a Phase 1?
In most cases yes, since a Phase 2 confirms a Phase 1's findings — though a known issue, such as a documented spill, can justify going straight to Phase 2.
