Disclosure: this comparison is written and published by DROZlegal. Claims about RelativityOne are drawn from Relativity's own published materials (its pricing page, technical documentation, and press releases) or named, dated legal-tech and business press, cited throughout, and were checked directly against Relativity's own site on September 16, 2026 — verify current features, pricing, and hosting regions directly with Relativity before buying. Claims about DROZlegal describe shipped functionality documented on this site. This article is general information, not legal advice, and reflects Ontario law and publicly available information as of September 16, 2026.
RelativityOne's Canadian footprint, checked against its own materials
Start with what's actually true, because it cuts against the pattern this kind of comparison usually follows. RelativityOne's own customer-story page names Borden Ladner Gervais LLP — Canada's largest full-service law firm, with offices across the country — as a RelativityOne customer. That's the vendor's own public marketing, not a leaked client list.
The reseller network backs that up. Per consulting.ca's February 4, 2021 coverage, FTI Technology expanded its RelativityOne offering into Canada that year, with Relativity's own Director of Commercial Partnerships, James Zinn, stating at the time: “Demand for our RelativityOne solution continues to grow in Canada.” Relativity's partner directory today also lists Heuristica and TransPerfect with dedicated Toronto pages. This isn't a brand-new 2026 development — it's a five-year-old, still-active channel.
On hosting specifically: per Relativity's own technical documentation, checked September 16, 2026, RelativityOne's deployment geographies include a Canada-Central Azure region. Treat that as a documented-but-not-independently-corroborated data point — help-site URLs shift, and we could not cross-confirm the exact regional designation against a second indexed source in this pass. Confirm current hosting-region availability directly with Relativity in writing before relying on it for a residency decision, the same way you'd confirm it with any vendor.
None of this makes RelativityOne a small-firm, self-serve Canadian product. BLG-scale adoption and an enterprise reseller network describe an Am Law-adjacent sales motion, not a plan a two-partner Ontario litigation boutique signs up for online.
The 2025 shift: generative AI folded into standard pricing
On October 8, 2025, at Relativity Fest, Relativity announced that its generative-AI review tools would move from optional add-ons to standard RelativityOne pricing and packaging — per the company's own PR Newswire release, CEO Phil Saunders framed it as “setting a new standard” for the industry. Per that release and Relativity's current pricing page, the bundle now includes, at no separate line-item cost to a RelativityOne subscription:
- aiR for Review — accelerates document analysis for relevance and key issues.
- aiR for Privilege — streamlines privilege review and flags indicators of privileged content.
- aiR for Case Strategy — builds case narratives, auto-generates fact chronologies, and supports deposition prep.
- aiR Assist — conversational data exploration (still in preview as of the announcement).
Not everything moved into the standard bundle. Data Breach Response, Translate, Relativity FOIA, and Legal Hold remain separately licensed add-ons per Relativity's own pricing page. For a firm already paying for RelativityOne's core review platform, folding the aiR review suite into the base price is a real, verifiable value shift — not a marketing rename of an existing feature.
What RelativityOne actually costs
Relativity publishes no numeric rate card. Its pricing page offers two structures — Pay As You Go, and Flex Commit on a one- or three-year term — and ends every path at “Request Pricing.” Third-party pricing trackers (not Relativity's own figures, and unverified by us) estimate a range from roughly $500 to $25,000 per month depending on data volume, with per-gigabyte hosting-plus-processing estimates in the $15–$30/GB/month range before licensing and support are added. Treat those as a rough starting point for a sales conversation, never as a quote.
DROZlegal's approach is different by design: current plans and pricing are published at drozlegal.com, flat per firm with every module included at every tier, rather than gated behind a request-pricing form.
The job RelativityOne is built for — and the one DROZlegal doesn't try to do
Be honest about scope, because pretending otherwise would be the kind of claim this program doesn't publish. RelativityOne is a specialist, enterprise-grade eDiscovery review platform: it's built to ingest, cull, and review document sets in the hundreds of thousands to millions, with a review team, a case manager, and often outside counsel all working the same dataset at once. Document review already consumes more than 80% of total litigation spending industry-wide — an estimated $42 billion a year, per the American Bar Association's own tracking as cited in Everlaw's January 2026 research — and RelativityOne's aiR suite exists specifically to cut into that number at scale.
DROZlegal is not that platform, and this post doesn't pretend it competes on that job. DROZlegal is a practice-automation spine for Ontario law firms: an event-driven system that carries work — intake, drafting, review, follow-up — toward done through 22 registered agent classes, 17 of which are manual-dispatch and propose-only by design. discovery_review is one of them: it proposes a first-pass relevance, privilege, or disclosure-category coding pass on the documents already sitting inside one case file, reviewed before it's ever accepted — a narrow assist tool embedded in a single matter, not a standalone review platform built to run a firm's biggest document-heavy file on its own.
Where DROZlegal goes deeper instead is jurisdiction-specific litigation infrastructure: a 241-entry Ontario court-form registry (188 generatable, 53 browse-only), DOCX authoring through LibreOffice-headless PDF conversion to CaseLines-ready packaging, and a case-detail page carrying eight tabs — overview, parties, documents, timeline, generate, offers, undertakings, and service records — so discovery status sits next to every open settlement offer against the same deadline clock. Settlement acceptance and court filing both remain behind permanent hard ceilings no autonomy setting can override, alongside trust-money movement, commencing litigation, engagement approval, and agent-initiated email send.
On data handling: DROZlegal's stored client data stays in AWS's ca-central-1 region, and AI processing runs under Anthropic's commercial API terms, which do not train on client inputs or outputs and delete them automatically within roughly 30 days. That's a precise, checkable claim — not “zero retention,” and not a substitute for confirming RelativityOne's own current hosting terms directly if your matter's document volume genuinely calls for that platform instead.
Where each platform actually lands, feature by feature
| Dimension | RelativityOne | DROZlegal |
|---|---|---|
| Built for | Enterprise eDiscovery review at scale — hundreds of thousands to millions of documents | Practice automation — intake through drafting to a lawyer's sign-off, one case file at a time |
| Canadian presence (per each vendor's own materials) | Named enterprise customer (BLG), reseller partners since 2021, a Canada-Central region listed in technical docs (unconfirmed independently) | AWS ca-central-1 only; stored client data never leaves Canada |
| Generative AI | aiR for Review, Privilege, and Case Strategy — standard since October 2025, no separate line item | discovery_review agent: first-pass coding proposal on one case file's documents, manual dispatch, propose-only |
| Pricing model | Pay As You Go or Flex Commit (1–3 yr); no public rate card, “Request Pricing” only | Published plans and pricing at drozlegal.com, flat per firm |
| Litigation-specific depth | Review workflows, privilege logs, case-narrative tools across any jurisdiction | 241-entry Ontario court-form registry (188 generatable), DOCX→PDF→CaseLines pipeline, eight-tab case file |
| Autonomy on consequential actions | Not detailed in the public materials reviewed for this piece | Six permanent hard ceilings (trust money, court filing, settlement, litigation, engagement, agent email send) no setting can override |
Who RelativityOne fits, and who doesn't need it
If your firm is handling a document-heavy matter — a merger investigation, a regulatory response, multi-party commercial litigation with hundreds of thousands of records to cull and code — RelativityOne's own customer base and its 2025 aiR bundle make a real, defensible case, and BLG's adoption shows it scales to a serious Canadian practice. That's a genuinely different job than the one DROZlegal is built for, and pretending otherwise wouldn't survive a second look from a litigator who actually runs review projects.
If your firm is small or mid-size, doesn't run RelativityOne-scale document review as a matter of course, and the actual bottleneck is everything else around a file — intake, drafting, deadline tracking, settlement offers, getting a factum assembled — that's the job DROZlegal exists for, on data that stays in Canada under a documented answer rather than a hedge. Worth checking before your firm signs a multi-year Flex Commit for review capacity it may only need on a fraction of its files.
Tracking which of these platforms bundles what, and when a pricing or AI-feature shift like October's aiR change actually affects your firm, is exactly the kind of thing worth knowing before a renewal conversation, not after — that's what the newsletter below is for.
