Strategy you can trace
to the source.
Prior Signal helps leaders make the high-stakes call — and defend it. We turn the records that matter — filings, policy, public data, and your own document troves — into strategy you can trace to the primary source. Applied AI and monitoring do the heavy lifting; the judgment is the product.
Five capabilities.One discipline.
Intelligence and analysis, applied AI, digital systems, strategic communications, and monitoring — five capabilities run as one discipline. Each feeds the same thing: strategy you can trace back to the record it stands on, kept current as conditions change.
Intelligence & Analysis
Trade-policy and regulatory analysis, public-records research, FOI/ATIP strategy, and complex-claims analysis — clear assessments, each one traceable back to the record.

Every output ties back to the record behind it. No claim without a reference; nothing that can't be re-examined later.
Data-resident
Designed for Canadian privacy, hosting, and governance requirements — model-agnostic, with self-hostable options for sovereignty-sensitive work.
Decision-ready
Built for leaders who need to act, explain, and defend the call — when a regulator, a board, or counsel reviews the work.
Most firms hand you a strategy you can’t check. We hand you one you can.
Plenty of firms will hand you a confident recommendation. Far fewer will show their work. Prior Signal is built the other way around: evidence first, AI as the engine, and a trail from every recommendation back to the record it stands on — so the strategy holds up when someone checks it.
Process, not promises.
Every engagement follows the same path. We scope the question, structure the records, verify and cite every finding, and keep the picture current — each step built to be checked.
Define the question
We start with the decision in front of you and the sources that bear on it — what you need to know, and what would change the answer.
Make the records legible
We extract and organize the relevant documents and data into something queryable — at scale, with applied AI doing the heavy lifting.
Check and cite
Every finding is checked and traced back to its source. No claim without a reference; nothing that can't be re-examined later.
Keep it current
Sources change and decisions evolve. We track what moves and update the picture, so the work stays useful past the day it's delivered.
See the method on a live, public problem.
End the Wait Ontario is the clearest worked example of the method. It turns freedom-of-information responses and government records on Ontario’s autism waitlists into a structured public resource — searchable data, decision tools, and downloadable datasets — where every published figure resolves to a primary source you can open and check. The result is hard to ignore: first-position Google ranking on the primary query, regular citation by major AI answer engines, and FOI-verified data that has surfaced in national and provincial news coverage.
The collaboration with Dr. Mrigank Shail — a communications strategist whose work has appeared on World Health Organization (WHO) channels — carried that foundation onto institutional channels. One joined system — records, structure, and reach — instead of a chain of handoffs.
A clip produced by collaborating strategist Dr. Mrigank Shail (not affiliated with WHO) was published on WHO's official social channels on October 29, 2025 — grounded research carried onto institutional channels.
EndTheWaitOntario.com holds first-position ranking on the primary query, sustained 2024–2026. Major AI search surfaces (ChatGPT, Claude, Perplexity) regularly cite the platform for autism waitlist data.
Anyone can claim their AI is accurate. This is one public page a prospect can open and check — the records, the method, and the result, in the open.
EndTheWaitOntario.com and Prior Signal are not affiliated with, endorsed by, or partnered with the World Health Organization.
The methodology came first. Twenty years came before that.
Prior Signal is not a pivot from advocacy. It is the culmination of a twenty-year career across hospitality, manufacturing, e-commerce, and public interest research — each chapter building a capability the firm now integrates and deploys.
The advocacy work through End the Wait Ontario was the chapter where the methodology proved itself at scale: first-position Google ranking for “ontario autism waitlist”, inclusion in WHO social content, and a data-driven platform that made fragmented public information impossible to ignore. That platform remains a separate, non-commercial project and is actively maintained.
But the methodology — the ability to take complex, fragmented information environments and make them legible, searchable, and strategically positioned — was built across all six chapters. Prior Signal is how that methodology reaches organizations that need it.

Spencer Louis Carroll
Spencer Carroll holds a Bachelor of Business (International Hotel & Resort Management) from Le Cordon Bleu Australia, completed in partnership with the University of South Australia. He built his operational foundation at Four Seasons Hotels, then moved into manufacturing at Canadian Soapstone, where he navigated tariff exposure, supply chain logistics, and cross-border trade disruption firsthand. He has run PG Closets — a custom closet fabrication and installation company — for over a decade, operating in-house aluminum and glass fabrication and managing everything from design through manufacturing to final installation. He then spent years on data journalism and FOI research through End the Wait Ontario, building the platform on a volunteer basis as a parent advocate into a resource that holds first-position Google ranking for “ontario autism waitlist” (sustained 2024–2026) and was included in content published on the World Health Organization’s social channels.
“I spent years building tools to hold institutions accountable through data — FOI analysis, data journalism, SEO infrastructure, digital systems. That advocacy work continues through End the Wait Ontario and always will. But organizations across every sector face the same structural problem: they’re drowning in fragmented information they can’t make legible or actionable. Prior Signal exists because the methodology I built has applications far beyond any single cause.”
Prior Signal applies that same analytical discipline to commercial and institutional clients. The advocacy work and the firm share a founder and a discipline — the ability to reshape information environments through integrated research, digital infrastructure, and sustained execution. They do not share a legal structure, a revenue model, or a mission statement. End the Wait Ontario is a non-commercial advocacy platform and remains actively maintained. PG Closets remains an active fabrication and installation operation. Prior Signal is a private, for-profit strategy firm serving commercial and institutional clients.
The decision to build an independent firm, rather than seek a role within the systems being analyzed, was deliberate. Independence is the foundation of credible analysis.
