(If you are behind a switchboard you may have to dial '0' or '9' (or another number) to get an external line.)
How the number is composed
00 is the international prefix used to dial somewhere outside of Saudi Arabia.
1 is the international code used to dial to Canada.
There are multiple city/area codes in use for Toronto. If does not work, you may try the others. The area codes used are: 416/647/289/905/437/365. (Not added because the number entered already seems to include an area code.)
18007692511 is the local number you wrote. The national prefix was removed from the number.
