Hi Ann E,
I have a subscription to ancestry.ca, which has digitized all the Ontario BMD records.
I have looked for Leila's marriage, but with no luck. But marriages are only available up to 1922 right now (due to privacy laws). She could easily have married after that.
But here is Alice's marriage and death:
