With 2+ years of foreign driving experience, new residents of Ontario with licenses ineligible for direct exchange (such as a license from The Netherlands), can skip the graduated licensing system and take the G2 road test directly. For example, see exchange foreign drivers license.
I recall reading or hearing that if one under these circumstances fails the G2 road test, then the credited foreign driving experience is annulled and one has to go through the full graduated system, thus forcing one to wait at least 20 months to take the G2 road test again. However, I'm unable to verify this information now.
What happens if one fails the G2 road test (G2 exit test) with credited foreign driving experience? Can one take the test again soon after, or must one indeed go through the full graduated system?
