What is the difference between temporary and permanent spousal support in Ontario?

In Ontario family law, spousal support can be ordered at different stages of a proceeding and for different durations. Temporary support (also called interim support) is ordered while the case is pending and is designed to maintain financial stability during the court process. It is not a final determination — the court can set a different amount at the final hearing.

"Permanent" support in the sense of a final order lasting indefinitely is what Ontario law calls "indefinite" support. It does not mean payment continues forever regardless of circumstances — it means no fixed end date was set, and either party can apply to vary it if circumstances change materially. True permanent, unalterable support is very rare.

Time-limited support — a final order with a fixed end date — is the third category. This is a final order but with a built-in expiry, after which the recipient would need to show material change or continuation grounds to have support extended.

Courts prefer final orders over interim ones, and they prefer clarity about duration. The type and duration appropriate for your case depends on your specific circumstances: length of marriage, career sacrifices, ages, children, and prospects for self-sufficiency.
