The practical question
Before a law firm turns on Copilot, uses ChatGPT or Gemini, or adopts AI inside a legal platform, does it know which tool is approved, what information it can receive, who checks the result and who remains responsible?
Law firms in Belleville, Quinte West, Stirling-Rawdon and across Eastern Ontario are being offered AI inside the systems they already use: email, document suites, research tools, practice-management platforms, transcription, drafting and meeting software. The issue is not whether AI can assist work. It is whether the firm can use it without losing sight of confidentiality, client information, account control and professional judgment.
CyberTECT is not a law firm and does not determine professional obligations. The Law Society of Ontario’s Technology Resource Centre remains the primary professional resource. This article translates the operational questions into the systems a smaller law firm actually runs.
Why this matters in a smaller law firm
In a small practice, the same few people may manage client files, Microsoft 365, trust-related workflows, conveyancing systems, e-signing, billing, banking approvals and vendor contacts. An AI feature can touch one piece of that environment, but the risk often sits in the surrounding permissions and decisions.
- Who owns the Microsoft 365 tenant, domain and AI subscriptions?
- Can staff use personal accounts or unapproved browser extensions for firm work?
- Which folders, shared mailboxes and matter records can a user already access?
- Who reviews an AI-assisted draft before it is sent, filed or relied upon?
- Can the firm remove access and continue if a lawyer, clerk, administrator or provider is unavailable?
Those are digital-operations questions, not just AI questions. They connect directly to the law firm’s confidentiality, continuity and client-service responsibilities.
A usable starting framework
1. Inventory what is already in use
List public chatbots, paid subscriptions, Microsoft Copilot, legal-platform AI features, transcription tools, browser extensions and connected assistants. Record the account owner, business purpose, users, information involved and whether the tool is approved, restricted or still under review.
2. Set information boundaries before experimentation expands
Staff should not have to guess whether a file is “anonymous enough.” Define what is permitted for low-risk experimentation, what needs approval and what is prohibited by default. Client-identifying information, privileged communications, banking details, identity records, passwords, trust information and full matter files need a deliberate firm decision—not an individual shortcut during a busy day.
3. Use firm-controlled accounts
A firm should know who owns each paid workspace, who can administer it, how MFA and recovery work, what happens on offboarding and how access is removed. Work that depends on a personal email address or personal subscription is difficult to supervise and may be difficult to recover.
4. Keep human review matched to the consequence
AI can produce fluent but incorrect material. The responsible person must verify facts, authorities, calculations, client details, dates, instructions and whether the output is appropriate for the file. A tool may assist a first draft; it does not take over the lawyer’s or paralegal’s accountability.
5. Review the data environment around the tool
Before enabling a tool that can draw from Microsoft 365, review external sharing, broad groups, inactive sites, shared links, former-staff access and the owners of sensitive repositories. Microsoft 365 Copilot respects existing permissions; it can make information a person already has access to easier to locate. See CyberTECT’s Copilot and confidential-files guide and OneDrive and SharePoint review guide.
Local firms still need a firm-wide control decision
Whether a firm is in Belleville, Quinte West, Prince Edward County, Napanee, Kingston or supporting clients remotely, location does not make client information less sensitive. The local reality does affect staffing: smaller teams often rely on a single office manager, bookkeeper, lawyer or external IT provider. That makes alternate access, vendor escalation and account ownership especially important.
The aim is not to create a 70-page policy. It is to put a practical, documented decision around the tools and workflows the firm actually uses.
Start with these five actions
- Identify every AI feature and account currently used for firm work.
- Stop personal or unapproved accounts from handling client information while decisions are made.
- Set a one-page interim rule: approved tools, prohibited information, human review and reporting path.
- Review Microsoft 365 sharing and high-risk data locations before enabling Copilot broadly.
- Assign an accountable owner and review date.
When a deeper review is worthwhile
A broader review is useful where AI touches client records, multiple users, connected Microsoft 365 data, practice-management systems, financial or trust-adjacent work, automated actions or external-facing communication. CyberTECT can help document the actual tools, accounts, permissions, vendors, recovery paths and operating decisions. It does not provide legal advice or certify Law Society compliance.
