My prediction is that Conservatives generally outperform the polls. Therefore, my prediction is that Conservatives will get a minority government with 140-150 seats.
Here are the current poll projections:

114 seats
The Conservative Party and New Democratic Party are tied for the projected average number of seats with 114 seats and are 56 seats from winning a majority government.
