Election Calculator Ontario

Use this Ontario election calculator to estimate how your vote might impact the provincial election results. The tool helps you understand the potential effect of your vote on seats and policies based on current polling data and historical trends.

How to Use This Calculator

To use the Ontario election calculator:

Enter the number of seats you believe your preferred party will win in the current election.
Select the current leading party from the dropdown menu.
Enter the total number of seats in the Ontario legislature (currently 124).

The calculator will show you the percentage of seats your preferred party is projected to win and how this compares to the current leading party.

Formula Used

Vote Impact Calculation

The calculator uses the following formula to estimate vote impact:

Seat Percentage = (Preferred Seats / Total Seats) × 100

Lead Difference = (Preferred Seats - Leading Seats) / Total Seats × 100

Where:

Preferred Seats - Number of seats you expect your preferred party to win
Leading Seats - Number of seats currently held by the leading party
Total Seats - Total number of seats in the Ontario legislature (124)

Worked Example

Let's say you believe the Progressive Conservative Party will win 50 seats, the current leading party (Liberal Party) has 45 seats, and there are 124 total seats in the legislature.

Using the formula:

Seat Percentage = (50 / 124) × 100 = 40.32%

Lead Difference = (50 - 45) / 124 × 100 = 4.03%

This means your preferred party is projected to win 40.32% of the seats, giving them a 4.03 percentage point lead over the current leading party.

Interpreting Results

The calculator provides two key metrics:

Seat Percentage: Shows what percentage of total seats your preferred party is projected to win.
Lead Difference: Indicates how much your preferred party leads or lags behind the current leading party in percentage points.

A positive lead difference means your preferred party is projected to gain seats, while a negative value indicates they are projected to lose seats.
