A detailed explanation of the vote and seat projection models that have been used to make these riding projections can be found here.
These riding projections are the best estimates of likely outcomes if an election were held on the last day of polling. The high and low results are the estimates of likely floors and ceilings, based on the high and low vote projection ranges. The probabilities listed beside each riding is the likelihood that, if an election were held on the last day of polling, the projection model would correctly identify the winner. It does not assign any probability to a particular trailing party winning the riding - if a projection gives the leading party a 75% chance of winning, there is a 25% chance that any of the other parties could win (though, in practice, most ridings are only contests between two parties).
