A signing authority matrix is a document that maps positions to the approval limits they hold for contracts, spending and banking actions. Executives and finance teams use it to keep commitments inside approved limits, speed up routine approvals and show auditors who could sign what. A board resolution authorises officers to bind the company, while incumbency records identify who holds each title.
TL;DR:
- A board resolution grants officers legal authority; record it in minutes, pair role limits with an incumbency certificate, and expect banks to request certified copies.
- Keep the initiator, authorizer, and reconciler separate; require dual signatures for high value or unusual transactions, and retain approval logs and supporting documents.
- State whether limits apply per transaction or across a period, specify whether taxes count, and define approval type, required evidence, and expiry dates.
- Review the matrix at least yearly and after reorganizations, officer changes, new business lines, regulatory shifts, or failed audits; assign one owner to control versions.

1. What a signing authority matrix looks like in practice
Most matrices are a grid. Rows list transaction types, columns list roles or dollar thresholds, and each cell states what that position may approve. Public-sector delegation instruments assign authority to positions identified by title, not to individuals, and the same habit works for private companies. Titles survive turnover, so you do not rewrite the document every time someone is promoted. You do need an incumbency certificate to confirm who currently holds each title, and using titles in resolutions reduces administrative burden when paired with one.
Typical transaction categories include:
- Contracts and agreements, split by value and term
- Operating spend such as invoices, subscriptions and travel
- Capital spend such as equipment, leases and property
- Banking actions such as payments, transfers and account changes
2. Why it matters: control, speed and audit readiness
A matrix answers the question "who agreed to this?" before anyone has to ask it. It also saves time, because people can avoid escalating routine items that sit within their limits.
- Control: unauthorized commitments become easier to spot and stop, and accountability sits with a named position.
- Speed: approvers know their limits, and counterparties can see who has the power to bind the company.
- Audit readiness: reviewers can use an evidence trail rather than reconstructing events.
A signing authority matrix is described by the Employment and Social Development Canada audit of delegation of authority as a critical internal control: it ties approvers to limits so commitments are not made without authority.
Auditors treat missing separation of duties as a common finding, and the Treasury Board Secretariat directive on financial authorities requires the initiator, authorizer and reconciler to stay separate.
3. Legal and governance foundations
Your matrix is only as enforceable as the instrument behind it. In a federally incorporated company, that instrument is a board resolution under the Canada Business Corporations Act or the provincial equivalent. The resolution gives officers the legal power to bind the corporation, and the matrix then spells out the detail.
- Record each resolution in the board minutes so the approval date and wording are beyond dispute.
- Expect banks and some counterparties to ask for a certified copy of the resolution, and a few may want notarization.
- Pair position titles with an incumbency certificate that names who holds each office today.
- Borrow the public-sector pattern of defined areas of authority, equivalency tables for positions and limits on sub-delegation. Those ideas keep a private matrix tidy as the company grows.
Think of the resolution as the source of power, the matrix as the working schedule and the incumbency certificate as the proof of who is currently in the chair. Remove one and the other two lose credibility.
4. Core elements every matrix must include
A usable matrix is specific. Vague fields such as "senior management" invite disputes, so each row should answer who, what, how much and under what conditions.
- Position title: the role, an incumbency reference and the effective dates.
- Transaction category: the area of authority, such as procurement, payroll or banking.
- Dollar threshold: the limit, stated as per transaction or aggregated over a period. State which one, because approving multiple invoices can add up to a substantial total.
- Authorization type: single signature, dual signature or reserved to the board.
- Documentation: certification, countersignature or supporting evidence required before the signature counts.
- Expiry or review date: so temporary limits do not quietly become permanent.
Pro Tip: Write thresholds as "up to and including" a dollar amount and decide once whether taxes are in or out. Ambiguity at the boundary is where disputes can arise.
5. Step-by-step: design, approve and publish the matrix
Start with how approvals actually happen today, then formalize the version you want.
- Map transactions and approval flows. List what the company signs and spends, and note who currently approves each item.
- Draft position-based thresholds. Set limits by title and risk, and prepare proposed resolution language alongside the grid.
- Obtain board approval. Have the board adopt the resolution and record it in the minutes.
- Issue the incumbency certificate. Confirm who holds each title as of the effective date.
- Configure your systems. Load approver lists and limits into your accounting, procurement and e-signature tools so the system enforces the matrix.
- Train approvers. Walk each person through their limits, the dual-signature rules and what to do when an item exceeds their authority.
- Tell counterparties. Share the relevant limits with banks and key suppliers, and update signature blocks where titles appear.
Keep the first release modest. A short matrix that people follow beats a complete one that nobody opens. For help with the workflow side, contract review workflows with AI show how automated checks can sit in front of signature.
6. Implementing controls: segregation of duties, secondary approvals and audit trails
The grid sets limits. Controls make them real.
- Separate three roles. The person who initiates a transaction should not authorize it, and neither should reconcile it afterward.
- Use dual signatures for high-value items, banking changes and anything outside normal patterns. A second approver is cheap compared with a recovered payment.
- Verify automatically. Systems should check each approval against the approver list and block anything outside the matrix, with logs showing who approved what and when.
- Retain the evidence. Keep signed resolutions and incumbency proofs for as long as your retention rules require. Our guide to mortgage file retention periods shows how those timelines are usually set. A common pitfall named in the CAM-I framework is skipping secondary authorization altogether.
7. Maintaining the matrix: review cadence, triggers and version control
A matrix goes stale the day the organization changes. Set a regular review, at least yearly, and add event-based triggers.
- Triggers: reorganizations, new or departed officers, new business lines, new regulatory requirements or a failed audit test.
- Ownership: assign one owner, usually the corporate secretary, finance or legal, to control versions and distribution.
- Temporary delegations: give them a start date, an end date and a written revocation path, and record them the same way as permanent ones.
- Version control: number each release, archive the old one and make sure only the current version is circulated.
8. Templates and a quick example layout
A compact schema is enough to start. Use a table with columns for transaction category, role or title, maximum limit, approval type and notes with incumbency reference.
- Multi-entity groups: add an entity column or issue one matrix per entity, and state where parent approval is required.
- Project-based delegations: time-box the authority and tie it to a project budget so it lapses on completion.
- Documents to attach: the minute reference for the resolution, the certified incumbency certificate and the effective date.
9. Our view: practical priorities when you adopt a matrix
Begin with the transaction types that carry the most risk, usually banking, contracts and large purchases, and leave the long tail for later. Write titles, not names, and keep the incumbency certificate current. Then automate the verification and logging, because manual checks can be harder to maintain during busy periods.

FAQ
Who has signing authority in a corporation?
The board of directors can authorise officers to bind the company through a resolution. Under the CBCA, that resolution is the instrument that legally lets officers bind the company. The matrix can set out each officer's limits.
What does "delegation of authority signature" mean?
It means a person signs under power handed to them by someone with greater authority, within stated limits. Public-sector instruments delegate to positions by title and restrict further sub-delegation.
What does "signing authority" mean?
Signing authority is the right to sign documents or approve spending that legally commits an organization. It is usually capped by dollar amount, transaction type or time period, and set out in a signing authority matrix.
What is a corporate resolution authorizing signatures?
It is a decision recorded in the board minutes that names the offices allowed to sign for the company and the limits that apply. Banks and counterparties may ask for a certified copy, as the CBCA guidance context suggests.
