A pre-mover list is not a mailing list. It is a weekly file of properties where the household has declared intent to move, delivered in whatever format the receiving system can actually use. The naming conventions vary by industry; the underlying data does not.
What is actually in a pre-mover list
A useful pre-mover list contains, at minimum, the property's address, its listing status, the date it entered the current status, the listing price, and a stable property identifier that persists across relistings. A better list adds historical context: how long the property has been on the market, whether the price has changed, whether this is a first listing or a relist.
BrightCat's pre-mover file carries all of the above, plus lifecycle classification: NEW, RELISTED, PRICE_CHANGED, SOLD, SUSPENDED, and TERMINATED. The classification is produced weekly from observed listing activity, not inferred from address changes or post-move records.
A pre-mover list identifies properties before the transaction closes. Post-mover files identify households after the move has already happened. The entire value is in the gap between the two.
Delivery formats that match the receiving system
Pre-mover lists serve distinct enterprise use cases with different technical environments. BrightCat delivers the same underlying data in three formats:
- Flat file (CSV or Parquet) — delivered weekly to a secure endpoint. The right choice for teams whose pipelines are already built around batch file ingestion.
- Snowflake Secure Data Share — the dataset mounts into the consumer's Snowflake account as a read-only database. The right choice for teams running analytics and workflow automation inside a warehouse.
- MCP connector — the dataset is exposed through the Model Context Protocol. The right choice for LLM-powered workflows where an agent queries the list directly.
Format is a delivery choice. The underlying pre-mover file is identical across all three modes.
How industries actually use pre-mover lists
Telecom acquisition
A household that has just listed their home is actively shopping for a new internet, TV, and phone provider. Telecom providers use pre-mover lists to reach these households during the decision window, not after the competitor's welcome kit has already arrived.
Insurance retention and acquisition
A move triggers a policy review. Insurance carriers use pre-mover data to retain current policyholders before they shop the market, and to acquire new customers whose existing policy is about to be cancelled.
Banking and mortgage origination
A listed property is a signal that a mortgage is about to be discharged, a new one originated, or a home equity line redrawn. Lenders use pre-mover lists to identify high-intent origination opportunities weeks before the close.
Direct marketing and mover services
The household that lists a home becomes a high-value consumer for dozens of downstream services: furniture, appliances, home services, subscription changes. Direct marketers use pre-mover lists to reach households at the point of maximum purchase intent.
What separates a production-grade pre-mover list
The difference between a pre-mover list that produces ROI and one that produces bounce rates comes down to four operational details:
- Refresh frequency. Weekly is the minimum useful cadence. Monthly files miss entire listing-to-sold cycles in hot markets.
- Identifier stability. Properties need to be tracked by a persistent identifier, not by MLS number or listing ID. MLS numbers reset when a listing expires and the property is relisted.
- Lifecycle classification. A raw list of listed properties is less useful than a list that distinguishes first listings, relistings, price changes, and suspensions.
- Known coverage and known gaps. A provider that documents its gaps is operationally trustworthy. A provider that claims perfect coverage is either lying or untested.
National coverage, continuous history
BrightCat's pre-mover data covers 5.8 million residential properties across all ten Canadian provinces, with continuous weekly history since 2014. The dataset has run without interruption through multiple market cycles, which means every property carries up to a decade of lifecycle history for longitudinal analysis.
Frequently asked questions
What is a pre-mover list?
A pre-mover list identifies households that have entered a move cycle — typically signalled by the property being listed for sale. It is a forward-looking signal, not a retrospective one.
How often is the list updated?
Weekly. Every cycle captures new listings, price changes, status changes, and sold events from the preceding week.
Is national Canadian coverage available?
Yes. The dataset tracks 5.8 million residential properties across all ten provinces, with continuous weekly cycles since 2014.
What format does the list come in?
Flat file (CSV or Parquet), Snowflake Secure Data Share, or MCP connector. The underlying data is identical across formats.
How is this different from a post-mover file?
A post-mover file tells you someone moved — after the fact. A pre-mover list tells you they are about to move, while decisions about new providers, policies, and services are still ahead of them.
Can I see a sample file?
Yes.

A pre-mover list is the earliest consistent signal of household movement in Canada. The format it arrives in is a delivery question. The signal it carries is what actually matters.
