Can I resubmit a minor variance application after it was previously refused in Ontario?

Generally, yes, a refused minor variance application can be resubmitted, though simply reapplying with the same materials and expecting a different outcome usually isn't an effective strategy, since the committee of adjustment will still be applying the same four-part legal test to essentially the same facts. A resubmission tends to have a meaningfully better chance where it addresses the actual reasons the committee gave for refusing the original application, whether that means redesigning the proposal, reducing the scope of the variance requested, or bringing new evidence that responds directly to concerns raised at the first hearing.

Some municipalities have their own procedural rules about resubmission, including possible waiting periods or restrictions in certain circumstances, so it's worth checking with the specific municipality about any procedural requirements before filing again. Rather than treating an appeal to the Ontario Land Tribunal and a resubmission as mutually exclusive options, it's worth weighing which path better fits the specific reasons for refusal: a resubmission is often better suited to genuinely fixable design issues, while an appeal may make more sense where the disagreement is really about how the committee applied the legal test itself.
