Four polls to include in our poll tracker; two from Nanos, one from Leger and one from Harris Decima. All have very different results and trends; Leger and Decima show a narrowing race with the Tories looking at another minority government, Nanos shows the Tories pulling away with a majority easily within reach. The net effect is no real change day over day for the Tories in our poll tracker, while the Liberals have seen some minor improvement since the election was called.
Depending on what polls you follow, either the Liberals are closing the gap or the Liberals are losing Canadians, so I'm not even going to try to analyze the results. What I will do instead is offer another graph that shows the distribution of the polls over time. Polls that cover more than one day are shown repeated over every day that the poll was taken while Nanos' tracking polls only are shown the day they are taken.
