A mile of cut and cover tunnel with three stations should cost somewhere in the neighbourhood of 300 million, maybe a bit more but not much. Even if we used the TTC's 90 million cost, then 500 million should be an absolute ceiling.
Remember the entire Canada Line cost just over two billion and it included six miles of tunnels, both cut and cover and a bored section under downtown and False Creek, along with a similar amount of elevated track.

100m per station is the price quoted for the Eglinton line which will have 90m platforms, the Spadina line extension which has 150m platforms, enclosed bus stations (some with more than 10 bays), and 'starchitect' designed stations are projected to be in the $135 million - $150 million range. Neither of the projects have been tendered however, but the stations on the Spadina line should be soon, which will be interesting given that since the TTC contracts all the parts separately will be able to see the exact costs of each station.
If the scope on the 8th Avenue subway doesn't balloon due to either the tunnel study (ie: stacked tunnel to move more operations underground earlier) or from councilors pushing for misguided 'world leading' design it shouldn't be more than $400m given its shallow depth, lack of need for assisted ventilation, likely avoidance of costly concourse levels, additional fire exits (stations will be close enough together) and fare barrier rooms.
Keep it simple and maybe taxpayers will trust that a second and third subway tunnel is practical to do in the future.
