Northwestern Ontario will need to get used to dialing ten digits for calls.
Starting next Wednesday, May 31st, ten-digit dialling will become mandatory for all local calls in the part of Northern Ontario served by the 807 area code, which includes White River and areas further west - ten-digit local calls were already introduced April 1st, but seven-digit calling has been allowed since, though it will no longer be possible after May 31st.
The move happened for the 705 region in 2011, to pave the way for a new area code to be added.
