📜 🇨🇦 CanadaBuys Tender Watch — Federal Opportunities & Awards

Government of Canada opportunities move fast and the open-data CSV is a moving target. This turns the official CanadaBuys tender-notice feed into a deduplicated, delta-only watch by buyer, province, and UNSPSC — with a receipt on every run.

Output is one tender_notice row per result; billing is pay-per-event, the value event being one procedure delta (a $0.02 start fee per run, then $0.02 per procedure delta plus one $0.10 source check per run that reads the source). Source: canadabuys.canada.ca.

Use cases by team

• Suppliers & bid teams: Watch the departments and UNSPSC categories you sell into and catch new solicitations on publication day.
• Regional resellers: Filter to your provinces so a federal feed becomes a local pipeline.
• Incumbency analysts: Track award outcomes and incumbent turnover across federal buyers.
• Procurement-intelligence vendors: Ship a bounded, deduplicated Canadian feed without owning the CSV-drift problem.

One of four record types, discriminated by record_type: tender_notice, award_notice, procedure_delta, or source_receipt.

Each row is flat JSON with these fields (from the dataset schema and the sample run; a field the source does not publish for a given row is null):

• record_type (string) — Discriminator.
• run_id (string) — Apify run id that produced this item.
• jurisdiction (string/null) — Source jurisdiction code.
• source_url (string) — Exact public request URL or endpoint supporting this item.

What you get

• tender_notice — open and amended tender-opportunity records with buyer, category, value, closing date and source URL
• award_notice — award records with winner names/ids, incumbent keys, award value, and the linked tender
• procedure_delta — watch-mode change events: new opportunity, notice updated, tender-to-award, incumbent change
• Province and UNSPSC/GSIN targeting so a national feed narrows to the segment you actually bid on
• source_receipt on every run — terminal state, counts, and a source-shape canary result, never billed

Every run also writes a RUN_RECEIPT record to its key-value store with the source checks it made and the counts it charged — diagnostics never land in the paid dataset.

⚙️ Sample inputs

1. Quick start — the Store example (this is what the sample above came from)

{
  "maxItems": 10,
  "watchMode": false
}

The sample run charged exactly: 1 × $0.02 apify-actor-start + 10 × $0.004 tender_notice + 0 × $0.006 award_notice + 0 × $0.02 procedure_delta + 1 × $0.10 source_check = $0.16 on the Free tier — snapshot preview rows are delivered unbilled; only the source check and the start fee were charged.

2. A smaller, narrowed run

{
  "maxItems": 5,
  "watchMode": false
}

Caps the run at 5 rows; same billing shape as the sample run above.

3. Watch mode on a schedule

{
  "maxItems": 10,
  "watchMode": true
}

The first run seeds a private baseline and emits zero deltas; every later run emits one row per change, billed at $0.02 each plus the $0.10 source check.

🔧 How it works

Source. The actor reads canadabuys.canada.ca — endpoints: https://canadabuys.canada.ca/en/tender-opportunities/tender-notice, https://canadabuys.canada.ca/opendata/pub/newTenderNotice-nouvelAvisAppelOffres.csv. Public pages and feeds only; nothing behind a login.

Transport. Plain HTTPS from the Apify platform, no proxy.

Watch semantics. Snapshot mode (watch_mode: false) returns a preview. Watch mode keys every record on a source-native id, stores a private baseline in a named key-value store, and on each later run emits one delta row per change (new / changed / removed). A blocked fetch is never diffed, so a source outage cannot show up as a mass removal.

Terminal states. A run ends NORMAL, CAPPED (your cap was reached), PARTIAL (something was withheld and the message says what), GENUINE_EMPTY (the source was read and truly had nothing in scope) or BLOCKED (the source refused or changed shape — the run FAILS loud and bills nothing). A zero-row run is never reported as a silent success.

Charging. Each procedure delta is charged at the moment it is pushed (procedure_delta); a row that fails to charge is not delivered, so the dataset count always equals the charged count. One source_check is charged per run that actually read the source.

How it works

Give it a date window and optional buyer / province / UNSPSC / keyword filters. It reads the CanadaBuys open-data tender-notice CSV (canadabuys.canada.ca/opendata) as an anonymous public client, normalizes each row into tender_notice and award_notice records, links awards back to their tender when linkAwards is on, and — in watch mode — diffs against a private baseline to emit only procedure_delta events. Every run closes with a source_receipt whose canary check catches CSV column drift before it can silently corrupt your feed.

Compliance & honest limits

• Public, logged-out official source only — no API key, login, cookie, CAPTCHA, or access-control defeating.
• Client-side targeting: filters are applied to the bounded window this actor fetched, not pushed into the upstream query.
• Watch mode's first run seeds a private baseline and emits zero deltas by design — deltas start on the second run.
• A source-confirmed empty window is SUCCEEDED-0: GENUINE_EMPTY; truncated runs are PARTIAL; exhausted retries are BLOCKED.
• source_receipt records are always emitted and are never billed.

⏰ Set it on a schedule

A single run is a snapshot. The value is the feed: open the actor in Apify Console → Schedules → Create new, add this actor with input 3 above (watch_mode: true), and pick a cadence:

• Daily — 0 7 * * * (07:00 UTC): catch changes within a day.
• Weekly — 0 7 * * 1: a Monday digest.

Each run is independent; keep the same input on the schedule so the results stay comparable. Schedules can also POST results to a webhook (Console → Integrations).

💰 Pricing example

Event	Free	Bronze	Silver	Gold
Actor Start (apify-actor-start)	$0.02	$0.02	$0.02	$0.02
Tender notice (tender_notice)	$0.004	$0.0036	$0.0032	$0.0027
Award notice (award_notice)	$0.006	$0.0054	$0.0048	$0.004
Procedure delta (procedure_delta)	$0.02	$0.02	$0.02	$0.01
Source check (source_check)	$0.10	$0.09	$0.08	$0.07

Worked at the live Free-tier price (watch mode, one delta per change):

• 8 procedure deltas: $0.02 start + $0.10 source check + 8 × $0.02 = $0.28
• 25 procedure deltas: $0.02 start + $0.10 source check + 25 × $0.02 = $0.62
• 500 procedure deltas: $0.02 start + $0.10 source check + 500 × $0.02 = $10.12

A run that delivers zero rows charges the $0.02 start fee plus the $0.10 source check (the source was read and reported empty). A BLOCKED run (source refused) fails loud and charges no value event. The start fee is charged once per GB of run memory; the default run memory is 512 MB.

Yield on the sample run: CAPPED: reason=CAPPED_MAX_ITEMS; pages=1/1; records=10. maxItems is a hard ceiling on what is delivered and billed, never a target.

⚖️ Legal & ToS

This actor reads public, logged-out pages and feeds published by canadabuys.canada.ca. It collects only what the source publishes to any visitor, identifies itself, and does not access accounts, private data or anything behind authentication. Use the output in line with the source's terms and your local law; the intended use is B2B research and monitoring.

❓ FAQ

Q: Do I need an API key or a login?
A: No. The source (canadabuys.canada.ca) is read logged-out; the input schema has no key field and the actor carries no secrets.

Q: Why did my run return 0 rows?
A: Read the run's status message. GENUINE_EMPTY means the source was read and had nothing in scope for your input (in watch mode the first run always seeds the baseline and returns zero deltas); BLOCKED means the source refused and the run failed without billing a value event — retry later or narrow the input. A zero-row run bills the start fee plus one source check.

Q: How many rows can one run return?
A: Up to maxItems (default 500). Raise the cap for a bigger run; you pay per delivered row.

Q: What does watch mode remember between runs?
A: A private baseline of source-native record ids in a named key-value store. Each later run diffs the live source against it and emits only changes.

Q: How fresh is the data?
A: Every run reads the source live at run time; nothing is cached between runs except the watch baseline. Put it on a schedule for a continuous feed.

Q: What formats can I export?
A: The dataset downloads as JSON, CSV, Excel, XML or RSS from the run's Dataset tab or the Apify API, and any run can push to a webhook or integration.

Q: How is this different from the other public procurement watches actors?
A: Same output shape and billing model; this one covers canadabuys.canada.ca. The siblings under Related Actors cover the other sources or slices — run several on one schedule for a combined feed.

🆘 Troubleshooting

• Run FAILED with BLOCKED → the source refused the request or changed its page shape → nothing was billed beyond the start fee; retry after a while, and if it persists open an Issue with the run id.
• Status says CAPPED → your cap (maxItems) was reached → raise it for a bigger run.
• Input validation error on start → a field is outside the schema's allowed values → start from the Quick start block and change one field at a time.
• Run TIMED-OUT → a very wide request on a slow day → raise the run timeout in Run options or narrow the input; what was delivered before the timeout is still in the dataset.
• First watch run shows no deltas → expected: it seeds the baseline; changes appear from the second run.
