Methodology

The interviews are compiled into a four week rolling average of 1,000 interviews where each week, the oldest group of 250 interviews is dropped and a new group of 250 interviews is added. The current wave of tracking is based on the final weekend of the election writ period ending Oct. 18th as well as the one week period ending Oct. 23rd. As we move forward, the tracking will revert to a four-week rolling average of 1,000 Canadians (250 per week).

A random telephone survey of 1,000 Canadians is accurate 3.1 percentage points, plus or minus, 19 times out of 20.
