Elections Ontario, on its YourBigDecision.ca site, has included a confirmation on its FAQ page that unofficial results of the referendum will be released as soon as they're counted on October 10th.
This is of great relief because the Chief Election Officer had been sending a different message in interviews with the Toronto Star as to when voters would "have a feel" for the results.
The following question and answer now appear on the YourBigDecision.ca site:
"How and when will the results of the referendum be shared with the public? On October 10th, the Election Ballots will be counted first, and then the referendum ballots. As soon as the referendum ballots have been counted, you will get the unofficial results. We expect referendum ballot counting to be finished early on Thursday, October 11, 2007."
