MyCase is a well-designed US practice management platform — but it was built for the American market. Ontario lawyers need LSO By-Law 9 trust accounting, Canadian data residency, and CAD pricing. Atticus was built for exactly that.
Start Free TrialMyCase is a US cloud practice management platform offering matter management, time tracking, billing, document storage, and a client portal. It is widely used by small to mid-size US law firms and is owned by AffiniPay, the same company that owns LawPay.
MyCase is built for the US legal market — its trust accounting is designed for US IOLTA rules, not for Ontario's LSO By-Law 9 requirements. All data is stored in US data centres, creating PIPEDA compliance concerns for Ontario firms. Pricing is in USD and configured for the US tax system, meaning HST handling requires manual workarounds.
Ontario lawyers choosing between MyCase and Atticus should focus on the regulatory mismatch: Atticus is built specifically for Ontario with native LSO trust accounting, Canadian data centres, CAD pricing, and AI document analysis purpose-built for Ontario legal practice.

MyCase trust accounting is built for US IOLTA rules. Ontario law firms need LSO By-Law 9 compliance — a different and more demanding regulatory regime. Atticus implements this natively from day one.
MyCase stores all data on US servers. Ontario firms handling client files with personal information need PIPEDA-compliant Canadian data storage. Atticus hosts all data in Canadian data centres.
MyCase charges $39–$89+ USD per user per month — after exchange rate, that is $54–$123+ CAD/user/month for a currency that fluctuates. Atticus is $149 CAD/month per lawyer.
Atticus AI understands Ontario legal context — it processes documents with Ontario law terminology, tracks Ontario limitation periods, and answers questions about LSO compliance from your matter files. MyCase AI is generic.
HST is built in to Atticus billing. Ontario limitation period tracking is automated. LSO By-Law 9 trust accounting is native. Every feature was designed for an Ontario practice — not retrofitted from a US product.
