What Canada Business Registry Guide is for

A read-only guide to five Canadian business registries: Corporations Canada (federal) and the registries of Ontario, Alberta, Nova Scotia and Quebec. It says which registry holds a business depending on where it is incorporated, gives the official page for searching and filing, the search fees the official pages publish (Ontario: profile report $8, document copies $3, certificate of status $26; Alberta: a government fee plus a registry-agent service fee, amounts not stated), the annual return timing where it could be read (federal CBCA: within 60 days following the anniversary, $12 online; Ontario: within 6 months of the fiscal year-end, changes within 15 days), the federal ISC rules, and where machine-readable data is documented. British Columbia, Manitoba, Saskatchewan, New Brunswick, Prince Edward Island, Newfoundland and Labrador and the territories were not researched and are reported as not covered. Nothing is searched, scraped or filed; every fact carries its source, date and verification level. General information, not legal advice.

Ask your assistant things like:

"We incorporated in Ontario: which registry holds our corporation and where do I file the annual return?"
"How much does an Ontario profile report, a copy of a document and a certificate of status cost?"
"When is the annual return due for a federal CBCA corporation compared with an Ontario corporation?"
"Do CBCA corporations have to report individuals with significant control, and how quickly must changes be recorded?"
"Is there machine-readable data for the Quebec enterprise register or for federal corporations?"

What it does

which_registry: Which registry holds a business for a province and the statute it is incorporated under (federal or provincial), for the five researched jurisdictions.
registry_links: Official pages for searching and filing per jurisdiction, exactly as read on the official sites.
annual_return_rules: Annual return timing and change-notice rules where an official page was read (federal CBCA and Ontario), and what was not verified for the others.
search_fees: Published search and document fees (Ontario amounts; Alberta fee structure) with what each official page does not state.
isc_requirements: The federal CBCA individuals-with-significant-control rules read on the official pages, with the details that could not be verified listed apart.
open_data_pointers: Where machine-readable registry data is documented (federal JSON, Quebec monthly dataset) and where the pages read mention none.

Data sources

Reference data from official sources (alberta.ca, donneesquebec.ca, ised-isde.canada.ca, novascotia.ca, ontario.ca); every answer states its source, date and validity period.

What it is not

Canada Business Registry Guide is independent; not affiliated with, endorsed by or operated by any government body, central bank, standards body or scheme operator. Names of rails, schemes and standards are used only to say what a tool works with. It is read-only: it never sends, pays, files or signs anything for you, and it never looks up private individuals.

Not advice. General information only, not legal, tax, accounting or payment advice. Canada Business Registry Guide is an independent tool: it is not affiliated with, endorsed by or operated by any government body, central bank, standards body or scheme operator. Rates, thresholds and rules change; check the cited official source and confirm with a qualified professional before you rely on a result.

Conventions

Read-only. Every tool reads public data or computes; nothing is written anywhere and nothing about the user is stored.
Result envelope. ok: true with data, or ok: false with a structured error (bad_input, not_found, upstream_error). degraded lists optional sources that were unreachable.
Rate limits. Free tier 60 tool calls/minute and 300/day per user (keyed on the user identifier supplied by the host agent, else client IP); Pro keys raise this. Over-limit calls return HTTP 429 with Retry-After. initialize and tools/list are never counted.
