Midwifery practice payroll: narrower than it looks, and easy to get backwards

Most midwives are not payroll at all

The default relationship in Ontario midwifery is a self-employed midwife billing her share of Ministry funding through the practice group, so no T4, no source deductions, and no CPP or EI withheld at that end. The group instead issues a T4A for the year's distributions, the standard slip for amounts paid to a contractor for services — see what a T4A is and which contractors get one. Getting this backwards, by putting a midwife on a T4 because it feels tidier, creates CPP and EI withholdings that were never owed and a reassessment risk if CRA later asks why a genuinely self-employed clinician was treated as an employee.

Who is actually on the group's payroll

Real payroll in a midwifery practice usually lives with the people who are not midwives:

• Reception and practice management staff — scheduling, billing submissions to the TPA, and client intake are ordinary employment, with a T4, EI, CPP, and WSIB coverage like any small clinic.
• A locum covering a rural or remote gap — usually another self-employed midwife billing the group directly under the Association of Ontario Midwives' locum arrangements, not an employee, which keeps her on the T4A side of the ledger too.
• Students and new registrants on a mentored caseload — typically still self-employed contractors of the group, but at a reduced share reflecting the mentorship, which affects her T4A total more than it affects payroll mechanics.

WSIB coverage is worth a separate look: employees of the group need it, and a self-employed midwife can opt into personal WSIB coverage even though she is not required to carry it, which some do given the physical unpredictability of attending births.

Your first non-midwife hire changes the group's remittance obligations

The moment a practice group hires its first receptionist or practice coordinator as an employee, it needs a CRA payroll account, a remittance schedule, and WSIB coverage that most groups previously avoided by keeping every clinical role self-employed. Ontario's Employer Health Tax has an exemption on the first tranche of annual payroll for eligible employers, which covers many small groups outright in year one, but the exemption shrinks as the group's total payroll grows across added staff and added midwives on T4A — see how to set up payroll for a first employee in Ontario before that first offer letter goes out. Vacation pay, statutory holiday pay, and ROE issuance for a receptionist follow the same Employment Standards Act rules as any small Ontario employer — nothing midwifery-specific changes there.

Parental leave is a funding question before it is a payroll question

Ontario funds a Parental Leave Program through an annual Ministry grant that helps a practice group offset the cost of a midwife's leave, running alongside — not instead of — the federal EI self-employed special benefits program that pays the midwife herself. Neither program puts her on the group's payroll; the grant is a group-level funding line, and her EI claim runs through Service Canada based on her own registration, which she must submit at least twelve months before she plans to claim. Once approved, maternity benefits run up to fifteen weeks, and parental benefits run up to forty weeks at the standard rate or sixty-nine weeks at the lower extended rate, split however the parents choose — figures worth mapping against the group's own locum budget before anyone is pregnant, not after. What the group's books need to get right is timing: the grant, any locum fees paid to cover her caseload, and the reduced distribution she draws while away all have to reconcile against a single absence, and a group that has never modelled that reconciliation before tends to discover the gap the month it actually happens.

Equalizing on-call is a scheduling problem the books should still see

Overnight call, weekend coverage, and holiday rotations are usually equalized across the group by a formula rather than paid as a separate wage, since the midwives sharing the rotation are contractors being distributed course-of-care income, not hourly employees. That formula still deserves a line in the books — a call-equalization adjustment, tracked per midwife per period — so that a heavier on-call quarter is visible in the numbers instead of disappearing into a flat percentage split that quietly rewards whoever was on call the least.
