Canada e-Invoicing Mandate
Post-audit GST/HST · voluntary Peppol exchange, federal procurement runs through the CanadaBuys platform
E-invoicing is not mandatory for B2B transactions in Canada, and no federal or provincial mandate has been announced or consulted on publicly. The Canada Revenue Agency accepts invoices in any readable form, including paper and PDF, provided they carry the information required for GST/HST input tax credits. Federal purchasing runs through Public Services and Procurement Canada's CanadaBuys electronic procurement solution, built on SAP Ariba, and practitioners report that suppliers transacting through it invoice electronically within the platform; Peppol is available for voluntary B2B exchange.
| Status | Voluntary |
|---|---|
| Legal basis | Excise Tax Act and the Input Tax Credit Information (GST/HST) Regulations set the required invoice content; there is no e-invoicing legislation. Invoicing of federal government buyers is a matter of procurement policy under Public Services and Procurement Canada's electronic procurement solution rather than tax law. |
| Phase-in | 1 phases, 2018 to 2018 |
| Scope | B2G: Voluntary · B2B: Voluntary · B2C: Not required |
| Format | Peppol BIS Billing 3.0, UBL 2.1, cXML · No mandated national standard; Peppol BIS Billing 3.0 is the usual choice for interoperable exchange |
| Platform | Peppol network (voluntary); SAP Ariba via CanadaBuys for federal government suppliers · Interoperability (4-corner) |
| Penalties | There is no e-invoicing-specific penalty regime in Canada because no mandate exists; standard GST/HST record-keeping obligations apply and inadequate records can result in denied input tax credits, reassessment and penalties under the Excise Tax Act. |

Canada e-invoicing guide on e-Invoice.appCanada e-invoicing: frequently asked questions
Is Canada likely to mandate B2B e-invoicing?
Nothing has been announced. Sovos reports that the Canada Revenue Agency set up a task force in 2021 to study the feasibility of a B2B e-invoicing mandate, looking at business efficiencies, sales tax compliance and the underground economy, but that internal study falls well short of policy. There is no public consultation, no discussion paper and no timeline. The first genuine signal would be a formal government consultation, and none is currently open.
Do provincial sales taxes change the e-invoicing position?
No. Provinces that levy their own retail sales tax, such as British Columbia, Saskatchewan and Manitoba, and Quebec with QST, impose their own registration and reporting duties, but none of them requires structured electronic invoicing. Harmonised sales tax provinces follow the federal GST/HST rules. Invoicing method remains a commercial choice throughout Canada.
Where must electronic invoice records be stored, and can they be held outside Canada?
The Canada Revenue Agency requires books and records to be kept at a place of business or residence in Canada and to be readable, auditable and accessible to CRA auditors; keeping them elsewhere requires permission from the CRA. Electronic records must be reproducible on request and adequately backed up. The full detail on cloud hosting, CRA electronic records approval and Peppol access point onboarding is covered in the detailed Canada guide on e-Invoice.app.

The measure took effect on 1 April 2026 and expires on 31 March 2027.
Canada British Columbia broadens PST 2026 Budget
