We handle the compliance complexity so you can focus on building your product.
Canadian Data Residency
All message data, logs, and consent records stored exclusively in Canada (AWS ca-central-1). PIPEDA and Quebec Law 25 compliant by design.
CASL Built In
Express and implied consent tracking, automatic STOP/UNSTOP keyword processing, 2-year implied consent expiry, and pre-send blocking — enforced by the API.
CRTC DNCL Integrated
Every outbound message is checked against the CRTC Do Not Call List before delivery. Exemptions (EBR, charity, political) supported.
Canadian Numbers Only
Provision phone numbers across all Canadian provinces. Our number validation covers all 60+ Canadian area codes — US numbers blocked by default.
Developer-First API
Familiar REST API with live and test mode keys, idempotency keys, HMAC-signed webhooks, and bilingual error messages (EN + FR).
Inbound SMS & Webhooks
Receive inbound messages and delivery receipts via webhooks. STOP replies automatically opt out subscribers and trigger your webhook.
Why Canadian businesses need a Canadian SMS API
The major US-based SMS providers treat Canadian compliance as an afterthought. Your data leaves the country, your bills come in USD, and CASL is your problem.
Canada's Anti-Spam Legislation carries penalties up to $10 million for organizations. HonkIO blocks non-compliant sends automatically — no US-based SMS provider does this.
The CRTC Do Not Call List must be checked before telemarketing sends. HonkIO checks it on every outbound message. The major US providers don't.
No major SMS provider stores data in Canada by default. HonkIO runs exclusively in AWS ca-central-1 (Montréal) — PIPEDA and Quebec Law 25 compliant from day one.
Why not just use a US provider?
For Canadian companies, compliance isn't optional. See the full comparison.
