Canner vs. Azure Database for PostgreSQL
Azure is the Postgres choice for Microsoft shops. Canner is the Canadian-owned one that sits next to your app.
Azure Database for PostgreSQL Flexible Server plugs into Entra ID, VNets and the rest of Azure, with a Canada Central region priced in CAD. Canner gives you Postgres on every plan, in one Canadian-owned platform with your app, cron and storage. Neither is right for every workload; here is where each one wins.
- Azure is stronger on enterprise integration (identity, networking, the Microsoft stack), on scale and on the breadth of its ecosystem. Canner has one region, no multi-zone failover and no read replicas.
- Where Canner differs: Canadian ownership. The Government of Canada’s own white paper says data in the cloud may be subject to the laws of other countries, and that a US-law organization can be compelled regardless of the data’s location. Microsoft is US-incorporated; Canner is not.
- On Canner the database, the app, cron jobs and object storage live in one place with flat CAD pricing. On Azure the database is one metered service among many, billed for compute, storage and backup storage separately.
| Feature | Canner | Azure Database for PostgreSQL |
|---|---|---|
| Data location | Montreal, Quebec — the only region | Canada Central is priced in CAD for Flexible Server, among many other Azure regions † |
| Jurisdiction | Canadian-owned, no US affiliate; not subject to the US CLOUD Act | Microsoft is a US-incorporated company. The Government of Canada’s own guidance says location does not remove exposure to foreign law: a US-law organization can be compelled “regardless of the data’s location” † |
| Managed Postgres | On every plan, including the free Starter: an isolated database and role per project (one on Starter, several on paid plans), DATABASE_URL injected. Postgres 17 or 18, chosen at creation | Separate service, billed on consumption. Canada Central, CAD: Burstable B1ms (1 vCore, 2 GiB) $0.0256/hr; B2s $0.1026/hr † |
| Pricing model | Flat CAD: Starter free, Live CA$9/month, Studio CA$149/month. Storage is one pooled limit per organization (5 / 25 / 100 GB); +50 GB blocks at CA$5/month | Compute per hour plus storage plus backup storage. Canada Central, CAD: storage $0.1753/GB-month; backup storage beyond the free amount $0.1455/GB-month † |
| High availability & read replicas | None. One region, one provider; no multi-zone failover, no automatic failover and no read replicas | Azure offers high-availability and replica options beyond what Canner has; see Microsoft’s documentation for the current specifics |
| Backups & point-in-time recovery | Scheduled encrypted backups with the retention you set, manual backups, verification with email alerts, restore into a new database or in place, and copies to up to 5 of your own S3-compatible buckets. Point-in-time recovery (1–35 days, into a new database) with the Dedicated instance add-on, CA$9/month per project | Backups kept 7 days by default, up to 35; point-in-time recovery included, with continuous log backup (RPO up to about 5 minutes); a restore always creates a new server; backup storage free up to 100% of provisioned storage † |
| Extensions | With the Dedicated instance add-on: pgvector, PostGIS, pg_trgm, pg_cron, hstore and others (14 in the catalog). No fdw or dblink | pgvector, PostGIS and pg_cron available † |
| Logical replication | With the Dedicated instance add-on: replication out to your own subscribers, and following an external server live for a no-downtime migration (never as a superuser). Physical replication is closed | Native publisher and subscriber; requires wal_level=logical and a restart † |
| Moving in and out | Migrate-in streams from any public Postgres server; pg_dump export, migrate-out and copy on every plan. `canner db migrate-in` from the CLI | See vendor documentation |
| What sits beside the database | Your app, cron jobs, object storage, scheduled SQL, cookieless analytics and a CLI, REST API and MCP server, in one dashboard | The database only. Compute, networking, identity, storage and scheduling are separate Azure services you assemble |
| Ecosystem & enterprise fit | A focused platform; Enterprise from CA$600/month by quote | Deep integration with Entra ID, VNets and the Microsoft stack, and a very large ecosystem |

When Canner is the right call
You are shipping a Canadian app or internal tool and want the database beside it: one place, one bill in CAD, Postgres on every plan, and no subscription, resource group or VNet to set up first. It matters most when your buyer asks about jurisdiction. Microsoft is US-incorporated, and the Government of Canada’s own guidance says a Canadian region does not remove that exposure. Canner is Canadian-owned, hosted only in Montreal, and not subject to the US CLOUD Act. You also get backups you can verify and copy to your own buckets, and point-in-time recovery on a dedicated instance for CA$9/month.
When Azure still makes sense
If your organization runs on Microsoft (Entra ID, Microsoft 365, Dynamics, a Windows estate extending to the cloud), Azure’s identity and networking integration is hard to beat, and Flexible Server gives you high-availability and replica options that Canner does not offer: Canner has a single region, no automatic failover and no read replicas. Azure is also the sensible pick when you need a database that scales beyond one server, or when an enterprise agreement and a platform team already exist. If a Canadian Azure region satisfies your residency requirement and nothing more, Azure is a sound choice.
