Each week, Harris/Decima interviews just over 1000 Canadians through teleVox, the company’s national telephone omnibus survey. The most recent data were gathered between April 26 and April 30, 2012 for 1,006 completes. A sample of the same size has a margin of error of 3.1% 19 times out of 20. With the exception of the most recent wave, the data points on the graphs represent two week waves, with roughly 2,000 completes per wave, and a margin of error of +/-2.2% 19 times out of 20.
