Since the August 19th projection, the Progressive Conservatives have slipped 1.1 points to 39.4% and two seats to 55.
The Liberals, meanwhile, are down 0.5 points to 32.1% but have picked up two seats, and now stand at 34.
The New Democrats are unchanged at 18 seats but are up 1.5 points to 21.6% support.
The Greens are up 0.2 points to 5.7%.
The Liberals picked up one of their seats in Ottawa and the other in the Hamilton/Niagara region.
The PCs are now projected to take eight seats in Ottawa and eastern Ontario, with five going to the Liberals and one to the New Democrats.
In Hamilton and the Niagara region, the PCs are now tied with the NDP at four seats apiece. The Liberals stand at two.
A lot of seats remain close, with the PCs leading by 5% or less in 20 seats and trailing by that amount in nine seats.
For the Liberals, they hold narrow leads in 10 ridings and trail by a small amount in 19 others, while the NDP is behind by 5% or less in three ridings.
This puts the Progressive Conservative range at between 35 and 64 seats. The upper range has not changed since the August 19th projection, but the floor has dropped by four seats. Only 37% of the PC's range is now in majority territory.
The Liberal range now stands at between 24 and 53 seats, an increase of three seats on the ceiling. The floor has remained the same. The range is now one seat short of reaching the minimum for a majority government. But the potential for a very bad showing still exists.
For the New Democrats, their upper range has now increased by one to 21 seats. That is still short of the Liberals' floor, however.
The number of close ridings in Ontario is huge, compared to the other elections scheduled for this fall. There are eight in Manitoba, two in Newfoundland and Labrador, one in Saskatchewan, and none in PEI. Ontario is the most unpredictable race of the five, and if the Liberal and PC numbers continue to converge the result could really be up in the air.
