Update Sept. 19: Corrected dates for Mainstreet, which were misreported in the iPolitics article.
Overall, these numbers show stability in the race: no party moves in the same direction in all three polls. There is nothing particularly noteworthy in the regional numbers from the Léger poll released by The Canadian Press.
There was also a Mainstreet riding poll in Portneuf--Jacques-Cartier showing a comfortable Conservative lead, as expected. I revised the regional adjustment for this riding to match the population split of 58% in Quebec City CMA and 42% outside (previously I had simply included this riding in the Quebec City CMA area). This made the projection almost exactly match the poll, so no riding-specific adjustment was necessary.
