STERIS Applied Sterilization Technologies (AST) runs contract sterilization and laboratory testing for device, pharmaceutical and cannabis manufacturers, and for a Canadian facility the useful question is never whether the network is large — it is whether the lane fits your devices, your volumes and your transport obligations. This guide sets out what the company publicly operates, what its Canadian sites actually list, what Canadian law requires when samples travel, and the criteria worth putting side by side with building in-house.
Quick facts
- STERIS AST describes a global offering of contract sterilization, testing and validation services, pitched as technology-neutral.
- Its publicly listed Canadian footprint is two sites: Edmonton, Alberta and Montreal, Quebec — both offering electron beam (E-beam) processing.
- The Montreal site is described as serving medical device, pharmaceutical and cannabis manufacturers; the Edmonton site is described as an irradiation facility serving cannabis growers and distributors in Canada.
- Moving a Category B biological substance in Canada carries defined relief conditions under the Transportation of Dangerous Goods Regulations, including packaging, a Category B mark, the shipping name and a 24-hour telephone number.
- Contract sterilization is a registered activity in the United States: an establishment engaged in processing a device must register and list under 21 CFR 807.20.
What a contract sterilization partner actually provides
A contract sterilization provider is not just a chamber you rent. The service lines that matter for a regulated customer are:
- Process validation. Establishing the dose or cycle that achieves the required sterility assurance level for each device family, and the evidence package that supports it.
- Routine processing. Running the validated cycle, with dosimetry or cycle monitoring, and issuing a certificate of processing per lot.
- Laboratory work. Tests that support validation and release — among them sterility testing, bioburden work and packaging testing against the relevant packaging standard.
- Documentation and traceability. Records that let a downstream auditor tie a shipped unit back to a processing lot.
STERIS AST's own site describes the offering as "global contract sterilization, testing, and validation services" and, separately, a "technology-neutral sterilization service offering." Both phrases come from the Canadian location pages, which matters because the same pages also tell you what is actually available in Canada.
The Canadian footprint
| Site | Address as published | Technology listed | Stated scope |
|---|---|---|---|
| Edmonton, Alberta | 9205 135 St SW, Edmonton, AB T6Y 0N4 | Electron beam, energy level 7 MeV, vertical beam; carrier dimensions 23.6 × 15.75 × 8.75 in (600 × 400 × 222.25 mm); carrier weight capacity 12 lb (5.5 kg) | "irradiation facility … offering electron beam (E-beam) decontamination services for cannabis growers and distributors in Canada" |
| Montreal, Quebec | 21100 rue Daoust, Sainte-Anne-de-Bellevue, Québec H9X 4C7 | Electron beam (E-beam) | "contract sterilization facility … offering electron beam (E-beam) sterilization services for medical device, pharmaceutical and cannabis manufacturers across the Americas" |
Two conclusions follow directly from those two rows, and both should shape a sourcing plan before any quotation is requested:
- A device that requires ethylene oxide or gamma processing will be routed outside Canada. Neither Canadian site page lists those modalities. Plan materials compatibility, dose-setting work and transit time around that.
- Capacity is expressed in carrier dimensions and weight. The Edmonton page publishes a 600 × 400 × 222.25 mm carrier envelope and a 5.5 kg carrier weight capacity, which is a useful first filter: product configurations outside that envelope cannot simply be assumed to fit a standard lane.
Capability pages change. Confirm current modalities, envelope limits and turnaround commitments with the provider directly, and record the answer with the date you received it.
What the workflow looks like end to end
Contract processing follows the same logical sequence regardless of vendor, and each stage has a different owner:
- Scope and quotation. Device families, packaging configuration, annual volumes, and the sterilization modality that the materials and the regulatory submission require.
- Validation. Dose setting or cycle development, supported by bioburden and dose-audit work, ending in a documented validated process for each family.
- Routine processing and monitoring. Every lot processed against the validated cycle, with the physical monitoring the standard requires.
- Laboratory testing. Sterility, bioburden, packaging integrity and ageing studies as applicable to the product and market.
- Release documentation. Certificates and lot records flow back to the facility, which then releases product on its own quality authority — the contract partner supports the decision, it does not make it.
That fifth point is where sourcing conversations go wrong. The processing site produces evidence; the legal manufacturer still owns the release decision, the technical file and the traceability chain. Write down who holds each artefact before work starts.
Transport: what Canadian law requires when samples move
If the workflow includes sending biological indicators, spore strips or clinical specimens to a laboratory — or sending instruments to a processing site — the shipment is regulated. Canada's Transportation of Dangerous Goods Regulations provide a specific relief provision for Category B infectious substances under UN3373, and it is short enough to quote:
> Parts 3 and 4, except section 4.22.1, and Part 17 do not apply to the offering for transport, handling or transporting of infectious substances that are included in Category B if (a) one external surface of the means of containment for the substances measures at least 100 mm × 100 mm; (b) the means of containment is in compliance with Part 5 (Means of Containment) and has displayed on the external surface (i) the mark illustrated in Part 4 (Dangerous Goods Marks) for infectious substances included in Category B, and (ii) the shipping name, on a contrasting background, next to the mark in letters at least 6 mm high; and (c) the 24-hour telephone number required under paragraph 3.5(1)(j) is displayed next to the shipping name on the means of containment.
The same regulations define the packaging itself. "Type P650 means of containment" is defined as a means of containment that complies with CAN/CGSB-43.125, the National Standard of Canada for packaging of Category A and Category B infectious substances, or — if manufactured outside Canada — with Packing Instruction P650 of the UN Recommendations and the national regulations of the country of manufacture.
| Requirement | Detail | Where it comes from |
|---|---|---|
| Label and mark | Category B mark plus the shipping name in letters at least 6 mm high, on a contrasting background, next to the mark | TDG Regulations s. 1.39(b) |
| Minimum surface dimension | One external surface of the means of containment at least 100 mm × 100 mm | TDG Regulations s. 1.39(a) |
| Emergency contact | A 24-hour telephone number displayed next to the shipping name | TDG Regulations s. 1.39(c) |
| Packaging conformance | CAN/CGSB-43.125, or UN Packing Instruction P650 for packaging manufactured outside Canada | TDG Regulations, "Type P650 means of containment" |
| Pressure capability | The primary receptacle or secondary packaging must withstand, without leakage, an internal pressure of 95 kPa | Packing Instruction P650 |
| Marking exemption note | Packages packed and marked under P650 are not subject to other requirements of the modal regulations | Packing Instruction P650 |
In practice, that translates into three purchases and one habit: packaging that is certified to the standard rather than merely leak-resistant, a supply of the correct Category B labels, a documented emergency number that is actually answered, and a habit of photographing the completed package before it leaves the building. The UN3373 specimen transport bags we stock are rated to 95 kPa and sized for the 6 × 9 in format that fits most catalogue mailers, and the 3-wall leak-resistant specimen bags cover the secondary-packaging role for specimens that stay in-house.
In-house or contract: the criteria worth comparing
No regulator publishes a single checklist for this decision, so the honest approach is to compare the obligations that exist either way. The table below is our framework, not industry data — treat the rows as questions to answer with your own numbers.
| Criterion | In-house | Contract |
|---|---|---|
| Capital and footprint | Equipment, services, shielding, validated space and maintenance are yours | No capital; you buy capacity per lot or per pallet |
| Cost at volume | Fixed cost falls as volume rises; low volume carries the full burden | Unit cost falls with volume commitments; small volumes stay viable |
| Turnaround and working capital | Cycle time is yours to schedule | Transit time and booking windows enter the release timeline |
| Validation ownership | You build and defend the validation package | Provider builds the process validation; you approve and hold the technical file |
| Revalidation and audits | Internal programme, internal audit trail | Provider programme; you audit the provider's records |
| Modality coverage | Whatever you install | Whatever the site offers — in Canada, currently E-beam only at the two listed sites |
| Traceability | One record system | Two systems to reconcile at release |
| Transport exposure | None beyond internal movement | Regulated shipments, packaging cost, and temperature or dose exposure in transit |
| Regulatory registration | Site obligations sit with you | US-processed devices: the establishment that processes them must register and list under 21 CFR 807.20 |
| Exit risk | Salvage value of equipment | Dependence on a lane you do not control |
Two rows deserve emphasis. First, modality coverage is a hard constraint, not a preference: if the device needs ethylene oxide, the Canadian E-beam footprint does not answer it. Second, registration follows the process, not the brand — under 21 CFR 807.20 an owner or operator of an establishment "engaged in the manufacture, preparation, propagation, compounding, assembly, or processing of a device intended for human use shall register and submit listing information for those devices in commercial distribution." A contract sterilizer is a processing establishment, so the registration obligation travels with the site that performs the work.
What to put in writing before signing
- The modality, the validated dose or cycle, and the standards the process is validated against.
- The carrier envelope and weight limits, and what happens when a product falls outside them.
- Which party owns each document: validation report, dose audit, certificate of processing, sterility results.
- Notification windows for process deviations, and the re-test or re-process path.
- Turnaround commitments with a stated clock start, plus the transport method and its packaging obligations.
- The audit right, the record retention period, and the format records come back in.
If your facility is also standardising its own monitoring programme while outsourcing processing, the 24-hour self-contained biological indicator 25-pack covers routine in-house checks, and the Biological Indicator 5-pack trial at CA $12.99 is a low-commitment way to test the format. Everything in that lane sits in the sterilization monitoring collection and under the sterilization compliance hub.

Frequently Asked Questions
Does STERIS AST offer ethylene oxide or gamma processing in Canada?
The two Canadian location pages published by STERIS AST describe electron beam processing at both Edmonton, Alberta and Montreal, Quebec. Neither page lists ethylene oxide or gamma at those sites. A product that requires those modalities should be planned around cross-border transport, and current capability should be confirmed with the provider before a lane is designed.
What is a Type P650 container in Canadian regulations?
It is a defined term in the Transportation of Dangerous Goods Regulations: a means of containment that complies with CAN/CGSB-43.125, the National Standard of Canada for packaging Category A and Category B infectious substances, or, if manufactured outside Canada, with Packing Instruction P650 of the UN Recommendations and the national regulations of the country of manufacture.
Do I need a dangerous goods declaration to ship a Category B sample in Canada?
Section 1.39 of the regulations relieves Category B shipments from Parts 3 and 4, with the exception of section 4.22.1, and from Part 17, provided the conditions are met: a minimum 100 mm by 100 mm external surface, compliant containment carrying the Category B mark and the shipping name in letters at least 6 mm high, and a 24-hour telephone number displayed next to the shipping name.
What pressure must the packaging withstand?
Packing Instruction P650 requires that the primary receptacle or the secondary packaging be capable of withstanding, without leakage, an internal pressure of 95 kPa, equivalent to 0.95 bar. Packaging rated to that figure is the practical way to satisfy the requirement.
Who is responsible for validation when sterilization is contracted out?
The processing site develops and documents the validated process; the legal manufacturer approves it, holds the technical file and makes the release decision. Agree in writing which party owns the validation report, the dose audits, the certificates of processing and the sterility results, and how long each is retained.
Does a contract sterilizer have to register with the FDA?
Under 21 CFR 807.20, an owner or operator of an establishment engaged in the manufacture, preparation, propagation, compounding, assembly, or processing of a device intended for human use must register and submit listing information for those devices in commercial distribution. A contract sterilization site performs processing, so the obligation attaches to the establishment doing the work.
