Projection Update: Mainstreet 9/29-10/1 and 9/25 Terrebonne Poll, Nanos QC Breakdowns

The following poll has been added to the model:
Mainstreet's 9/29-10/1 national poll (national results only; current weight among national polls: 34%)
Mainstreet's 9/25 Terrebonne poll
Nanos' 9/11-20 and 9/21-30 QC breakdown
Full regional breakdown from the Léger 9/27-30 national poll added this morning
For a full list of included polls, see previous Projection posts.

The Mainstreet poll shows almost no movement. The projection moved slightly against the Grits due to Mainstreet's still-weak Liberal number gaining more weight through more recency.

Adding the Nanos QC numbers and full Léger breakdown made almost no difference.

The Terrebonne poll resulted in a small riding adjustment.

Projection as of the latest national poll (midpoint: September 30)
CON - 148.6 (36.4%)
LIB - 146.7 (33.1%)
NDP - 19.6 (13.2%)
BQ - 19.4 (5.1%)
GRN - 2.7 (9.0%)

IND - 0.6
PPC - 0.5

The projection is delicately poised. The Tories are ahead in the total seat win probabilities, but the Liberals have the projected lead in more seats. It's a coin toss! Without the turnout adjustment, the Liberals would have a 7-seat lead (9 if counting seats ahead), which would roughly translate into a 55-60% chance of winning a plurality for an election taking place now.

Seats changing hands since the last projection:
- In QC, the BQ takes Saint-Hyacinthe--Acton from CONs.
- In QC, the BQ takes Longueuil--Saint-Hubert and Hochelaga from LIBs.
- In ON, CONs regain Vaughan--Woodbridge from LIBs.
