Two calculators for the arithmetic Ontario practices do every month. Both are free and need no account, and neither asks for anything about you or your clients.
Three-way trust reconciliation calculator
Check whether the reconciled trust bank balance, the trust ledger control balance and the total of your client ledgers agree — and, when they do not, see the short list of things that usually cause a gap of that shape. It also flags a client ledger that has gone negative, which the three totals hide whenever they net out.

Open the calculatorOntario limitation period calculator
Work out Ontario limitation deadlines from the date each period actually runs from, including the fifteen-year ultimate limit, the short notice periods that expire long before two years, and the 2020 emergency suspension.
Counts time the way the Legislation Act does.
Open the calculatorThese are calculators, not legal or accounting advice. They only see the figures and dates you type in, they cannot tell you whether your records are complete or correct, and rules change — your firm remains responsible for its own compliance.
