Organizations Connect with our Members


Dear OADO members,

The OADO is joining with the Ontario Hazardous Materials Responders Association (OHMRA)!

It’s going to take us a while to transition to the DO Branch of OHMRA.

To say ‘thank you’ to all of you for sticking by us, we’re going to pay your membership to OHMRA for 2020.

We’re looking forward to this change and the new benefits it will bring to our members.

Thanks for coming with us!

The DO Branch executive of OHMRA

If you’re new to the OADO and were looking forward to joining, we’d like to direct you to the OHMRA website instead.
