Can a dependant get an interim support order while a full claim against the estate is still being decided?

Yes. Dependant support litigation under Part V of the SLRA can take time to resolve fully, and Ontario courts have the power to order interim support so a dependant can meet immediate needs while the larger claim is still working its way through the process. An interim order isn't a final ruling on eligibility or amount — it's a stopgap based on the information available at that point, and the eventual final award can end up higher, lower, or structured differently once the full claim is decided.

Courts granting interim support still look at the same basic questions as a final award — is there a genuine dependency relationship, and does the estate have funds available to draw on — but with less complete evidence than a full hearing would produce. This makes interim relief valuable for a dependant facing real financial hardship while waiting, but it isn't automatic or guaranteed simply because a claim has been filed. Anyone in this position should raise the possibility of interim support with a lawyer as soon as the need arises, rather than waiting for the main claim to work its way to a conclusion.
