Who uses GroceryPulse
CPI nowcasting for macro desks
Close the 3-week lag between retail price movements and the StatCan CPI print. The CGPI weekly signal is the highest-frequency input to the Food-purchased-from-stores sub-index available today.
Consumer-sector equity research
Track banner-level price competitiveness for L.TO, EMP.A.TO, MRU.TO, and WN.TO. Detect category markup compression and promotional intensity as it happens.
Retail competitive intelligence
Benchmark an independent or regional grocer's category pricing against the Big 3 at the city level. A tenth of the cost of NielsenIQ.
Academic & policy research
Licensed full-panel access for inflation-expectations research, pass-through analysis, and regional-disparity studies.

FAQ
Is the data licensable for redistribution?
Internal use is included with the subscription. Redistribution, sub-licensing, or embedding in a downstream product requires a written license — contact sales for terms.
How long is the historical window?
The continuous panel begins June 2026. Subscribers can commission historical backfills from select retailer archives — contact sales.
Is the index ever revised?
Price observations are append-only, and the published index is recomputed from the full observation history under the current, versioned normalization code. When methodology or normalization changes, the change is dated and documented, and the superseded series remains available (the v1 fixed-base series via series=v1). Subscribers receive point-in-time vintages, so the figure as published on any given date stays reproducible for backtesting.
Do you cover Walmart or Costco?
Not today. Walmart coverage is on the Q3 2026 roadmap pending a residential-proxy or licensing arrangement. Costco is member-only and unlikely to be feasible without a commercial partnership.
