If you are planning to Volunteer with WOMBA you will require a Police Background Check.
If you live in Woodstock, you can just go online and sign up there.  The turn around time is about 5 days.
If you live outside of Woodstock, you have to call the OPP station, book a time to go in with the form to fill out the Police Check application in person.
It is about a 1 month wait to just get in to fill out the application and then the wait time for approval has been quite the wait as well.
Thanks
WOMBA
