Canadian Trademarks Database is the federal trademark register published by the Canadian Intellectual Property Office. It carries applied-for and registered Canadian trademarks together with certification marks, distinguishing guises, geographical indications and plant breeders’ rights denominations, searchable by mark, owner, application or registration number and international registration number.
Domain Rating is a dated Ahrefs snapshot of domain authority. PetroHrys Score is an independent editorial assessment of the directory’s practical business value. They are separate measurements and are never combined. Domain Rating values are dated historical Ahrefs snapshots. Domain Rating is a dated historical measurement of the shared domain, not an assessment of this individual registry page. New measurements are not collected because the Research Center does not depend on mandatory authenticated APIs. Where several registries are published on one measured domain they repeat that domain’s single dated snapshot rather than each carrying a figure of its own. Domain Rating is a third-party metric produced by their respective providers, not by PetroHrys.com. Each recorded value carries its provider and the date it was measured, and describes the domain that was measured rather than one page on it. No source has been consulted for authority score, estimated traffic and referring domains, so they are not published for any record.
Open The search form is served directly with no account, sign-in or landing barrier, with its search fields and the database’s own currency date visible on the page.
This registry is a distinct system hosted on the shared ised-isde.canada.ca platform.
Assessment
Strengths
The Canadian Trademarks Database can be searched free of charge and without an account, directly from the Canadian Intellectual Property Office.
CIPO states the database "provides access to over 140 years of Canadian trademarks data" and that a searcher can "search and study more than 1.4 million Canadian trademarks".
Coverage includes "all active and inactive marks that were cancelled, expunged, abandoned or refused after 1979", so a lapsed mark stays traceable.
The database publishes its own currency on the search page, which read 2026-08-05 when this record was verified.
Limitations
It records trademarks, not businesses. An entry establishes nothing about whether the owner is an incorporated or registered entity, and nothing about its legitimacy or standing.
Unregistered common-law trademark rights exist in Canada and appear nowhere in the database, so a clear search is not a clearance opinion.
CIPO publishes a disclaimer about relying on the database and advises that searching intellectual property is complex enough to warrant a registered agent.
The Domain Rating shown is a dated measurement of the shared departmental domain ised-isde.canada.ca, not of this database.

Best for
Checking whether a brand name or logo is already applied for or registered as a Canadian trademark.
Establishing the owner of record, the filing date and the current CIPO status of a Canadian mark.
Not recommended for
Confirming that a company legally exists, which is a corporate-registry question and not a trademark one.
Clearing a mark on its own, because unregistered common-law rights arise in Canada and appear in no register.
Preparation checklist

Common mistakes
No common mistakes recorded yet.
Establishing required submission assets requires submitting a listing and observing the result. That has not been done for any directory in this dataset, so it is not published rather than estimated.

The PetroHrys Score is a first-party editorial assessment, not a third-party
authority metric. It is the weighted sum of the ten factors above, divided by ten, so the number
on this page is reproducible from the values shown. Each factor is scored from 0 to 10 by a human reviewer and weighted as shown. The definitions describe what was weighed, not a rubric: no threshold or formula maps a directory onto a value, and two reviewers could reach different numbers. The score is reproducible from the factors shown on every record, but it is an editorial judgement, not a measurement.
