How does this tool help with deadlines in Small Claims Court?

This tool helps you calculate deadlines in Small Claims Court by applying Ontario’s procedural rules (Rules of Small Claims Court) to your specific dates.

What’s the difference between “after,” “before,” and “between” when I calculate dates for Small Claims?

Use “after” to calculate deadlines small claims rules set after an event, “before” to calculate deadlines that must be met before an event, and “between” when you want to calculate dates in Small Claims by counting the number of days between two events using the court’s method.

Does the calculator adjust Small Claims Court deadlines for weekends and holidays?

Yes. The tool automatically checks for weekends and Ontario court holidays. If a deadline falls on a holiday, it moves the deadline to the next business day, as the rules require.

Why does the calculator give two dates for “before” deadlines?

In some stiuations, the tool shows both the formal rule-based date and a recommended earlier date. This helps you avoid accidentally shortening the notice period and provides a safer practical deadline.

Can I use this tool to explain how the deadline was calculated?

Yes. After you run a calculation, the tool provides a plain-English explanation showing how it counted the days, whether holidays were skipped, and which rule logic it applied. You can also copy or email the full result and explanation directly from the tool.
