If you want to vote strategically, so as to prevent any given party from
getting the expected majority in a given riding, the following site

is excellent for
* giving visibility by reporting consolidated polling results,
* charting those over time, and
* making projections on likelihood of any particular outcome.
If your own party is falling behind, and not likely to win, but another
party is doing better and could work to unseat a party you would prefer
to not win, then the results show which party could work to your
advantage in the pursuit of that objective.
The site reports on their accuracy for previous predictions:
