OHIPay vs MDBilling.

MDBilling.ca was one of Ontario's longest-running OHIP billing services. RBC (Royal Bank of Canada) acquired it as part of the bank's healthcare strategy and consolidated it under the Dr.Bill brand RBC also owns. Today the MDBilling marketing site redirects to dr-bill.ca and new sign-ups flow into Dr.Bill. A legacy MDBilling login portal still exists for established users.

To be clear, the MDBilling product and its billing service did not disappear. They continue inside Dr.Bill. But the tool you would evaluate today, and the pricing you would pay, are branded and delivered as Dr.Bill's. So in 2026, "MDBilling vs OHIPay" is really "Dr.Bill vs OHIPay," and that is how the rest of this page is written. (See Sources for the acquisition report and the live redirect.)

The number you billed at with MDBilling was 0.25% of what the Ministry actually paid you, and the merger did not change it. It carried straight into Dr.Bill: the self-serve tier a new MDBilling search lands on today, Dr.Bill Essentials, is still 0.25%. OHIPay charges the same 0.25%. So at low volume your old MDBilling rate, the current Dr.Bill rate, and OHIPay all cost about the same.

What the move to Dr.Bill did not add is a ceiling. OHIPay stops charging once the monthly bill reaches $29.99 plus HST. Dr.Bill Essentials lists no cap, so its 0.25% keeps climbing with your billings, exactly as MDBilling's did. The two lines cross at roughly $12,000 per month in paid remittance (0.25% of $12,000 ≈ $30). Below that, the rate you already paid and OHIPay's are the same. Above it, OHIPay's capped fee costs less, and the gap widens the more you bill.

If you already bill with MDBilling, you are inside the scale leader, and it has advantages OHIPay does not. The product is now owned by RBC, which gives it bank-grade backing and balance-sheet stability a newer independent tool cannot match. It carries the full operational history of MDBilling itself, one of Ontario's longest-running billing services, with your existing account, claim record, and support relationship living on inside it. It bills across three provinces: Ontario, British Columbia, and Alberta, which matters if you practise in more than one. And it runs a genuine full-service Comprehensive tier (1.95%) where an agent handles your billing end to end. OHIPay has none of these: it is Ontario-only, software-only, and newer. If any of that is decisive, the Dr.Bill product is the stronger fit, and we say so plainly. The same holds if your MDBilling setup already works and you would rather not move at all.

The login you have still opens, but it is Dr.Bill behind it. Typing mdbilling.ca redirects to dr-bill.ca, and the legacy MDBilling portal that established users still sign into hands you the Dr.Bill product and Dr.Bill pricing through the old door. The merger does not force you to do anything. But if you are re-evaluating anyway, it is worth knowing that the thing you are re-evaluating is Dr.Bill today, not the MDBilling of a few years ago.

If you do switch, plan for two things. First, your history: before leaving any billing tool, ask how to export your past claims and remittance records so your paper trail comes with you. Don't assume it is portable by default. Second, re-onboarding: moving to any new billing software means re-establishing your MC EDT / GO Secure submission connection and re-entering your provider setup. It is a one-time step whichever tool you land on, but budget for it rather than being caught out by it.

What OHIPay adds on top of the 0.25% you already know. A hard cap: once your monthly remittance clears roughly $12,000, OHIPay's fee stays flat at $29.99/month plus HST instead of scaling the way MDBilling's did. That keeps your cost predictable rather than volume-linked. Rejection advisories that never block a claim but tag each warning with the specific OHIP rejection code they are trying to prevent, built into the single 0.25% software tier with no upsell to a 1.95% agent tier to get help with rejections. Dr.Bill markets "proactive error detection," but whether its self-serve tier blocks or merely warns, and how it surfaces rejection codes, is not publicly documented. And documented Ontario-native depth: IPTMA inpatient-rounding automation, out-of-province reciprocal (RMB) billing, named-premium auto-calculation (MRP E082/E083/E084, after-hours E409/E410), the daily Billing Sheet for rounding, and remittance-advice (RA) reconciliation. Where the Dr.Bill public pages are silent on an equivalent, we mark the matrix "not publicly documented" rather than assume absence. New accounts start with 2 months free.

Stay on the Dr.Bill product, or simply stay put inside your existing MDBilling account, if you want bank-backed scale, if you bill in more than one province (Ontario, BC, or Alberta), or if you would rather hand billing to a fully outsourced team than run software yourself. The Comprehensive tier (1.95%) puts an agent on your claims to key and chase them end to end, which no software-only tool, OHIPay included, replicates. And if your current setup already works, not switching is the lowest-effort option. OHIPay is the better fit if you want to keep billing in-house, keep the cost capped and predictable, and lean on Ontario-specific automation. It costs less once your monthly remittance clears ~$12,000.
