Until recently, the only people who spent life in prison were people designated dangerous offenders. That requires a special hearing.
In the past, the max for first degree murder was 25 years before parole eligibility even if there was more than one victim. Consecutive sentencing was recently introduced, so now people can be sentenced to 25 years x 2 before parole eligibility.
Typical sentence for second degree murder, especially domestic, is 10 years.
It all depends on the circumstances.
A few supplementary thoughts:
A life sentence is a life sentence, and a date of parole eligibility is just that - a date on which you MAY be eligible for parole. Many will never get out, and will serve their full life sentences. Clifford Olson was never getting out, Robert Pickton is never getting out, Paul Bernardo etc. Those people and many others less known will die in prison because their crimes were too heinous and they will never not be considered dangerous. So, we’ll continue to give them parole hearings as required, turn them down for parole ad infinitum, until their natural lives are over. Life sentence.
Dangerous Offenders are not automatically in jail for life, though an indeterminate sentence can and usually does have that result. It is difficult, but not impossible, to be granted parole as a dangerous offender. Many people are initially surprised by the fact that DO status cannot be applied to murder convictions (or treason for that matter) because who is more dangerous than a murderer? But it makes sense when you consider that a life sentence for first or second degree murder doesn’t require any additional mechanism to keep somebody behind bars for life - you just never grant them parole. DO status is for criminals whose crimes of violence/sexual assault may not qualify for a life sentence, but who are too dangerous or habitual to be let out.
As you noted, judges now have the discretion to stack periods of parole eligibility for multiple murder convictions. It’s not limited to two - we’ve already had at least three offenders who have 25 x 3 for 75 years before being eligible to apply for parole. Thus far, judges have not given out sentences that would be expected to far exceed the natural lives of the convicted. For example, Bruce McArthur was convicted of 8 murders but has parole eligibility after 25 years, because he’s already old. He will never be let out. Dellen Millard committed three murders, and can’t apply for parole for 75 years. His cases are under appeal, but its a good bet he will never be let out either. Judges have a lot of discretion here, and have used it. The law is so new that precedent is still fairly scant.
So, looong story short the answer to the OP’s question is there is no LWOP equivalent to the US, but there is effective LWOP:
-never grant parole to somebody with a life sentence
-never grant parole to somebody with Dangerous Offender status, even though their crimes may not carry a life sentence
-for people convicted of multiple murders, stack the periods of parole eligibility such that they will effectively be in jail for life without a chance at parole until they are very old, and then deny it if they make it that far
Sorry for the long post!
