Clause is a US-based platform. Atticus stores all Ontario client files and trust records on Canadian servers by default — aligned with Law Society of Ontario guidance on cloud storage of client confidential information.
Clause is specialized smart contract tooling, and Ontario lawyers still need separate practice management, billing, and trust accounting. Atticus is $149 CAD per lawyer per month for the complete Ontario practice platform.
