If you are paying or receiving spousal support in Ontario, the arrangement you started with will not necessarily be the arrangement you end with. The short answer is yes: spousal support can be changed, reduced, or terminated. The more useful answer is that it depends on how the order or agreement was structured, and whether your circumstances have changed enough to justify revisiting it.
Support arrangements generally come in one of three forms:
Each can be changed, but the process and threshold differ depending on which one applies.
A temporary, or interim, order is made early in a case, before trial, to establish support while the matter is ongoing. Because these orders are made quickly and without a full trial record, courts have historically approached them under a standard of "rough justice." They are understood to be provisional, expected to be superseded once the matter is resolved on a complete record.
It might seem this would make temporary orders easy to adjust. In practice, the opposite is true. Courts are generally reluctant to vary a temporary order before trial, precisely because it is already temporary and already expected to change. Revisiting it every time circumstances shift would invite piecemeal litigation and turn each stage of a case into its own mini-trial. Case law describes a party seeking to vary a temporary order on an interim basis as facing a high bar, often requiring compelling or "clear and unequivocal" evidence, not merely any material change. Courts generally expect parties to wait for trial, where a full record allows the judge to correct any imbalance, including through retroactive adjustment.
A final order, by contrast, is the product of a trial or a negotiated resolution both parties intended to be conclusive. Once that full record exists, the ordinary material change test discussed below applies. It is a genuine threshold, and final orders are meant to provide stability, but it is a more established and workable standard than the heightened caution courts show toward temporary orders. In short, both require a material change, but temporary orders carry an added layer of judicial reluctance, since judges expect the interim arrangement to be resolved by trial rather than fine-tuned along the way.
For final orders, a party generally cannot return to court simply because they have changed their mind or the arrangement feels unfair in hindsight. They must show a "material change in circumstances."
This concept comes from the Supreme Court of Canada's decision in Willick v. Willick. The Court held that a change must be significant, and it must be one that, if known to the court at the time of the original order, would likely have resulted in different terms. The question is not simply whether something has changed, but whether it was something the original order-making judge did not, and could not reasonably, contemplate. A foreseeable or anticipated change generally will not qualify, even if it later occurs.
Examples that might meet this threshold include:
A modest raise or a temporary rough patch usually will not be enough, and courts generally require that the change have some degree of permanence rather than being short-lived.
These outcomes do not always go hand in hand.
Typically occurs when circumstances have shifted but the underlying need for support has not disappeared. For example, if John later takes a lower-paying job for legitimate reasons rather than to avoid paying support, a court may reduce, rather than end, what he owes Jane.
A bigger step, usually requiring that the need for support has effectively ended. This might occur if the recipient becomes self-sufficient, remarries or enters a new marriage-like relationship (a relevant factor, though not automatically determinative), the support term expires, or the payor retires and can no longer sustain the same level of payments. Even indefinite support, which does not mean "forever," can eventually be terminated once the underlying need has genuinely ended.
Some agreements or orders include a "review" clause, setting a date or event at which support will be reassessed. This differs from a variation: a review does not require proving a material change, since the parties or court simply revisit the arrangement as planned.
A variation is triggered by something unexpected occurring outside a scheduled review, and generally does require that threshold. If your agreement has a review clause, knowing the date and trigger can make updating support far more straightforward than a full variation application.
If your arrangement comes from a separation agreement rather than a court order, the rules can differ depending on how it was drafted. Some agreements set out specific terms for revisiting support; others are silent, in which case general principles, including the material change threshold, tend to apply similarly. Both parties can also agree to change support terms without going to court, provided they are both willing, though documenting any changes properly remains advisable.
As with duration, the Spousal Support Advisory Guidelines can offer a useful benchmark for what a revised support amount might look like given new circumstances. As with the guidelines generally, though, they remain advisory rather than binding, and a court can and will depart from them where the facts call for it.
Spousal support is not set in stone the moment an order or agreement is signed. Incomes rise and fall, health changes, people retire, and relationships evolve, and the law generally allows support to change along with these developments.
The process for having a change recognized, however, depends heavily on the type of order involved and the specific facts of your situation. If you believe your circumstances have shifted enough to justify revisiting your arrangement, it is worth speaking with a family law lawyer who can assess whether you meet the applicable threshold and help determine the best path forward.
