About the Study

These are some of the findings of an Ipsos poll conducted between June 7 and 8, 2018, on behalf of Global News. For this survey, a sample of 4,175 Ontario eligible voters was interviewed online (Ontarian eligible voters aged 18+ from Ipsos' online panel). All eligible voters on the Ipsos online panel were invited to participate in the Election Day Poll; however, panelists could only complete the survey after they had voted.

Weighting was employed to balance demographics to ensure that the sample's composition reflects that of the adult population according to Census data and to provide results intended to approximate the sample universe and to reflect the actual outcome of the election. The precision of Ipsos online polls is measured using a credibility interval. In this case, the poll is accurate to within ±1.7 percentage points, 19 times out of 20, had all eligible Ontario voters been polled. The credibility interval will be wider among subsets of the population. All sample surveys and polls may be subject to other sources of error, including, but not limited to coverage error, and measurement error.
