Contact lenses are federally regulated medical devices, the same category as a hearing aid or a surgical glove. Yet the rules covering who can sell them to you, and what paperwork you need first, are written province by province. Two people ordering the same box of Biofinity on the same afternoon, one in Vancouver and one in Fredericton, are shopping under different laws.
The patchwork explains a lot of the confusion online, including a few claims on retailer websites that don’t hold up.
Do you need a prescription to buy contact lenses in Canada?
In most of the country, yes. But the requirement doesn’t come from Ottawa.
Health Canada licenses contact lenses as Class II medical devices under the Medical Devices Regulations. Corrective lenses have carried that status for years, and decorative or cosmetic lenses joined them on 16 July 2016. What federal law governs is the product: manufacturing standards, safety, labeling, recalls. It says nothing about whether you personally need a prescription to buy a box.
Dispensing is provincial. And in most provinces the legislation is direct about it. Manitoba’s Optometry Act treats selling contact lenses with any spherical, prismatic or cylindrical power “otherwise than on prescription” as practising optometry without a license. Nova Scotia’s Dispensing Opticians Act says no dispensing optician may supply an optical appliance “except upon receipt of a prescription.” New Brunswick, Newfoundland and Labrador use nearly identical wording. Ontario’s College of Opticians puts it plainly: only opticians, optometrists and medical doctors may legally dispense prescription contact lenses in the province.
British Columbia is an outlier. BC amended its Opticians Regulation in 2010 to allow repeat prescriptions to be filled without a regulated eye care professional involved, and gave opticians authority to issue prescriptions themselves. Look at where Canada’s online lens retailers are headquartered and we’ll see a pattern: Clearly, KITS, PerfectLens and VisionPros are all BC companies.
Other provinces’ regulators pushed back on that arrangement in court and lost. Ontario’s optometry and opticianry colleges sued Essilor, which owns Clearly, to stop online sales into the province. The Ontario Court of Appeal ruled against the colleges in April 2019, finding that delivery is “a commercial element of dispensing that requires no application of professional healthcare skills” and that the transactions weren’t sufficiently connected to Ontario to fall under its health professions legislation. The Supreme Court of Canada declined to hear a further appeal that October.
What Canada doesn’t have: there’s no Canadian equivalent of the US Contact Lens Rule, the regulation that forces American sellers to verify your prescription with your eye doctor and gives the office eight business hours to object. No federal Canadian rule requires any retailer to contact your prescriber. If you see a claim that “Canadian regulations allow online retailers to sell without verifying your prescription,” treat it carefully: it’s describing a BC provincial change and an Ontario court ruling, not a national rule.
| Province or territory | Prescription required? | Who may dispense contact lenses |
|---|---|---|
| British Columbia | Repeat prescriptions can be filled without a professional involved | Opticians, contact lens fitters, optometrists, physicians |
| Alberta | Yes | Optometrists, physicians, opticians authorized for the restricted activity |
| Saskatchewan | Yes, under college standards | Licensed contact lens practitioners, optometrists, physicians |
| Manitoba | Yes, by statute | Opticians, optometrists, physicians |
| Ontario | Yes | Opticians, optometrists, physicians only |
| Quebec | Yes for corrective lenses; cosmetic lenses unrestricted | Optometrists, opticians, physicians |
| New Brunswick | Yes, and the Act covers cosmetic lenses too | Certified contact lens fitters, optometrists, physicians |
| Nova Scotia | Yes | Opticians with contact lens certification, optometrists, physicians |
| Newfoundland and Labrador | Yes | Board-certified dispensing opticians, optometrists, physicians |
| Prince Edward Island | Unsettled since its Dispensing Opticians Act was repealed in July 2025 | Check with provincial health authorities |
| Yukon, Northwest Territories, Nunavut | No territorial requirement located | Opticianry appears unregulated |
Nova Scotia is mid-transition to a new Regulated Health Professions Act as of this writing, so its rules may shift. If your province appears unsettled above, your provincial college of optometry is the place to ask.
How long does a contact lens prescription last?
You’ll read everywhere that Canadian contact lens prescriptions expire after one year. That’s common practice, not law.
No Canadian statute sets a maximum validity period. What exists instead is a mix of professional guidance. The Nova Scotia College of Optometrists says prescriptions for contact lenses “can be up to one year in length.” Quebec’s Ordre des optométristes sets something closer to a floor, advising that validity normally shouldn’t be less than a year. The Canadian Association of Optometrists recommends no more than two years. Newfoundland and Labrador’s college leaves it entirely to the optometrist’s judgment based on your eyes. Alberta’s standards do the same, requiring an expiry date be recorded without fixing what it should be.
Retailers set their own thresholds regardless. Clearly requires a contact lens prescription issued within the last 12 months. So even in a province with no legal expiry, the seller’s policy may be the practical constraint.
Why won’t your glasses prescription work for contacts?
This trips up more first-time buyers than anything else on the list. You have a valid, current glasses prescription in your hand, and you still can’t order contacts with it. The reasons are physical, not bureaucratic.
Start with distance. A spectacle lens rests roughly 12 millimeters in front of your cornea. A contact lens sits directly on it. Moving a lens closer to the eye changes its effective power, which is why any correction stronger than about 4.00 dioptres has to be recalculated before it becomes a contact lens power. A person wearing minus 6.00 glasses typically needs a slightly weaker contact lens, and someone at plus 6.00 needs a slightly stronger one.
Then there’s shape. A contact lens has to physically fit the curve of your eye, which means two measurements a glasses prescription has never contained: base curve and diameter. Your optometrist takes these with a keratometer and by measuring your visible iris diameter. Neither number can be calculated from your glasses prescription. As one clinical text puts it, corneal diameter plays a larger role in how a soft lens fits than base curve does.
Finally, material. A contact lens rests on living tissue that needs oxygen. Water content, oxygen transmissibility, deposit resistance and replacement schedule are all clinical judgments about your specific eyes. Health Canada is blunt about the stakes, naming corneal ulcers that “can perforate or scar the cornea in 1 or 2 days” among the risks of poorly fitted lenses.
So a contact lens prescription is the output of a different appointment than the one that produced your glasses prescription. BC’s regulator stated the distinction cleanly: a contact lens prescription isn’t an expected result of a routine eye examination, it’s the expected result after a fitting has been completed.
What happens at a contact lens fitting?
A fitting is a separate clinical service layered on top of a full eye exam, and it usually spans more than one visit.
It starts with a conversation about how you’ll wear the lenses: dailies versus monthlies, sports or screen work, whether you’ve worn lenses before. Then come measurements a routine exam skips, including corneal curvature readings, iris diameter, and a tear film assessment to check whether your eyes will tolerate lenses at all. If you’re being fitted for multifocals, the optometrist also tests which eye is dominant, usually by blurring each eye in turn with a plus lens and asking which feels worse.
Next you get a diagnostic lens on the eye and wait. Hydrogel lenses settle in about five minutes, silicone hydrogels closer to twenty, and the fit can’t be judged until they have. The optometrist checks centration, movement and coverage, then does an over-refraction to confirm the power is right on your eye rather than in theory.
You’ll be taught insertion, removal, cleaning and your wear schedule. Alberta makes that instruction mandatory. Then you go home with trial lenses and come back, usually a week or so later, for a progress check. Only once that’s complete is the prescription finalized.
Ask what the fitting fee covers. Published Canadian clinic price lists in September 2026 put a fitting charged as a separate line item at roughly $50 to $90 for standard soft lenses, with toric and multifocal fittings at the higher end and specialty scleral fittings running near $300. What varies more than the price is what’s included. Some clinics fold trial lenses and all follow-up visits into one annual fee. Others bill each visit. Ask before you book.
What do the numbers on your prescription mean?
Once you have the prescription, you’ll be asked to transcribe it at checkout. Each value does a specific job.
Power, written as PWR, SPH or D, is the strength of the correction in dioptres, negative for nearsightedness and positive for farsightedness. Base curve, BC, is the curvature of the back of the lens in millimeters, commonly between 8.3 and 8.8. Diameter, DIA, is how wide the lens is, usually 14.0 to 14.5 for soft lenses. If you have astigmatism, you’ll also have a cylinder value and an axis between 0 and 180 degrees telling the lens which way to point, which is why toric lenses are built to resist rotation. Multifocal wearers have an ADD value, usually written as LOW, MED or HIGH rather than a number, because each product bands them differently.
And then the one that surprises people: the prescription names a specific lens product, not just numbers. That’s because base curve, diameter, material and optical design are fixed properties of each product rather than options you can mix. CooperVision’s own fitting guide makes the point neatly. MyDay Multifocal is 8.4 by 14.2. Clariti 1 day Multifocal is 8.6 by 14.1. Biofinity Multifocal is 8.6 by 14.0. Switching products changes curvature, diameter, water content and oxygen transmissibility all at once. A glasses prescription can be filled with any blank the optician has because the numbers get ground in. A contact lens can’t.
Will your provincial health plan pay for any of this?
Partly, and less than most people expect. No province or territory covers a contact lens fitting, and none cover the lenses themselves outside narrow medical-necessity cases. Ontario states it flatly: eyeglasses, contact lenses and elective refractive surgery are not covered.
What provincial plans do cover is the eye exam, and only for certain ages or conditions.
| Province or territory | Routine eye exam coverage |
|---|---|
| British Columbia | Ages 18 and under, 65 and over; medically required exams at any age |
| Alberta | Ages 18 and under, 65 and over, one per benefit year |
| Saskatchewan | Under 18 annually; annual diabetic eye exams at any age |
| Manitoba | Under 19 and 65 plus, one exam per two years |
| Ontario | 19 and under annually; 65 plus every 18 months; ages 20 to 64 annually with a qualifying condition |
| Quebec | Under 18 and 65 plus annually; emergency exams for everyone |
| New Brunswick | Low-income children 18 and under; no general adult coverage |
| Nova Scotia | Children under 10, and 65 plus, once per two years |
| Prince Edward Island | Diabetic retinopathy screening every one to two years; no general coverage |
| Newfoundland and Labrador | No provincial coverage for routine exams |
| Yukon | Seniors 65 plus up to $124.10 every two years; children’s program for low-income families |
| Northwest Territories | Not covered by the territorial plan; extended benefits for seniors 60 plus and low-income families |
| Nunavut | Optometric services not covered; ophthalmologist exams covered |
Quebec is worth a special mention for parents. Its See Better to Succeed program reimburses $300 toward glasses or contact lenses for children under 18 with a prescription, once every 24 months, and the amount doesn’t vary with what you spend. Registered First Nations and recognized Inuit individuals are covered for exams and corrective eyewear through Non-Insured Health Benefits, separately from any provincial plan.
Most Canadians fill the rest through work benefits. Employer vision plans typically run as a flat dollar allowance covering glasses and contacts together, commonly around $200 to $250 every 24 months according to Canadian benefits surveys from 2016 and 2020. Treat those as dated benchmarks rather than current figures. Prescribed contact lenses also count as an eligible medical expense at tax time, though the credit applies only above an income threshold, so one purchase rarely triggers it alone.
Where do Canadians buy contact lenses?
In person, the country is consolidated into a handful of groups. FYidoctors is the largest doctor-led network, with more than 270 locations under its own banner and around 370 across its wider group. Specsavers arrived in Canada in 2021 and reached 250 stores by December 2025, then added 111 more inside Loblaws, Real Canadian Superstore and Zehrs locations through a partnership announced in July 2025. New Look Vision Group quietly runs one of the biggest footprints of all through its banners: IRIS at 142 locations, New Look Eyewear at 93, Vogue Optical at 88 and Greiche & Scaff at 44. Costco Optical has more than 90 Canadian locations with independent optometrists attached, though it sells contact lenses only in warehouse, not online in Canada. Walmart Vision Centres, LensCrafters, Pearle Vision and Bailey Nelson round out the field. Hakim Optical, long a fixture, entered creditor protection in 2025 and has closed roughly 40 stores.
Online, Clearly is the largest, owned by EssilorLuxottica and based in Vancouver. KITS is publicly traded and also Vancouver-based, and it owns ContactsExpress, so two sites that appear to compete are one company. PerfectLens ships from Burnaby, Fresh Lens ships free with no minimum, and VisionPros ships across Canada with free shipping over $99. A few sites with .ca domains ship from outside Canada entirely, which is worth checking before you order.
Contacts are Canada’s most-online vision category. The Vision Council’s Consumer inSights Canada research found 29% of Canadian contact lens buyers purchased online in the first half of 2025, up from 23% a year earlier. Eyeglasses, by contrast, held flat at 87% bought in person. Reorders travel well online. Custom-fitted frames don’t.
The channel boundary is dissolving from both directions. FYidoctors sells lenses online with a subscription. Specsavers markets contact lens supply against your insurance allowance. Clearly operates physical stores with eye exams. Choosing between online and in person is now less about who has a storefront and more about who checks your prescription and how fast the lenses arrive.
How does ordering online work?
You’ll be asked for the same set of values at every Canadian checkout: the lens product, base curve, diameter, power for each eye, plus cylinder and axis if you have astigmatism and ADD if you wear multifocals. Pack size and quantity follow.
What differs is what happens next, and there are three live models in Canada. Some retailers ask you to upload or scan the prescription itself. Clearly has a phone-based scanner that reads the values off the page. Others let you type the values in from your lens box without uploading anything. And a few run a US-style verification voluntarily: KITS and ContactsExpress will take your optometrist’s name and fax number, contact the office, and proceed if nobody responds within eight business hours. That mirrors the American rule, but in Canada it’s a business choice rather than a legal obligation.
Which raises a fair question. If no Canadian law requires verification, why does every checkout ask for prescription details at all?
The answer is tax. Corrective contact lenses are zero-rated for GST and HST under the Excise Tax Act, but only when supplied under the authority of a prescription for a named person. In Contact Lens King Inc. v. Canada, decided by the Federal Court of Appeal in 2022, a retailer that sold to Canadians without collecting prescriptions was reassessed and lost, because it couldn’t produce evidence that valid prescriptions existed. CRA has since confirmed that a customer’s own declaration that they have a prescription isn’t sufficient evidence, and in April 2025 specified what a retailer should record instead: the issue date, the name of the eye care professional, and the prescription values. A Canadian retailer that skips the paperwork pays the tax itself. That evidentiary risk, more than any health regulation, is what shaped the checkout you’re filling in.
One practical consequence at checkout: your lenses should show no GST or HST, while contact lens solution, cases and cosmetic lenses are taxed normally at your province’s rate. A mixed order produces a partly taxed invoice, which looks like an error but isn’t.
Delivery timing depends on whether your lenses are stocked. In-stock spherical lenses generally arrive within three to seven business days in urban Canada. Toric, multifocal and rigid gas permeable lenses are usually ordered in from the manufacturer, which adds time. VisionPros quotes three to six business days standard, with custom lenses taking up to five weeks. PerfectLens warns that specialty lenses may take two to three weeks. Plan reorders before you run out rather than after.
What about ordering from US or overseas sites?
It’s legal. The Medical Devices Regulations carve out importation for personal use, so bringing in lenses for yourself is outside the federal licensing scheme.
Whether it’s worthwhile is another question. Contact lenses carry no customs duty at any value under tariff item 9001.30.00, so the widely repeated warning about duty above $150 doesn’t apply to lenses. Tax is a different story. Courier shipments from the US are tax-free only up to $40, and once a carrier fronts the tax it typically adds a disbursement fee with a minimum in the $15 to $20 range. On a small order, the fees can exceed the tax itself. You also give up easy returns, Canadian warranty support, and the recall notification path that runs through Canadian licence holders. Health Canada’s Medical Devices Active Licence Listing lets you check whether a product is licensed here before you commit.
What should you do first?
If you’ve never worn contacts, book a fitting rather than an eye exam, and say on the phone that contact lenses are the goal. The two appointments aren’t the same thing, and showing up expecting one to produce the other wastes a visit.
If you already wear lenses and just need more, check your prescription’s expiry date and ask your optometrist for a written copy of your contact lens specifications if you don’t have one. Your rights here depend on where you live. In Ontario, your glasses prescription must be handed to you automatically and free, but your contact lens parameters come only on request and only after you’ve paid for the fitting. In British Columbia, whoever fits your lenses must give you a free copy of your contact lens record once the fitting is done, and that one is in the regulation rather than a professional guideline. Quebec goes furthest: your optometrist has to put the prescription in front of you at the end of the visit, release it without delay when asked, respect your choice of where to fill it, and can’t charge you for it. Alberta requires your optometrist to hand you a written copy of your contact lens specifications once the fitting is complete.
Then compare on the things that vary: price per box, shipping threshold, how long a special order takes, and what happens if the lenses don’t suit you. Those differences are usually wider than the price difference on the lenses themselves.
