UPDATE 9:50 A.M. - Employees with Canada Post have been allowed to return to work.
As it turns out the suspicious substance was Bio Kleen chlorine free oxy bleach, according to Kelowna Fire Platoon Cpt. Tim Light.
"Which is a company that deals in health food, natural products, and stuff like that," he says.
"The fellow it was sent to let us know what he was expecting from this company, so he gave us a bit of a heads up for our Hazmat entry team."
The household bleach came in a powdered form, and Light speculated that the package could have broken during transit, releasing the powder from its container.
It's unclear how many employees were evacuated from the building, but eight people were secluded for their own safety, as to not cross contaminate anyone else.
An unknown amount of white powder found at the Canada Post building on Baillie Avenue has forced an evacuation this morning.
Authorities say eight employees were potentially exposed to the substance and have been secluded from other workers outside the building.
Hazmat crews responded to the scene and the RCMP has cordoned off the area.
The person who the package was addressed to has been contacted and reportedly says he was expecting a shipment of vitamins and some other health products.
This isn’t the first time that a questionable substance has been discovered at the Kelowna postal outlet, in fact it's the third time this year that Hazmat has been called for the same precautions.
Each of the previous calls have been false alarms.
We’ll have more details when they become available.
