Best appointment reminder and no-show tools for Canadian clinics and service businesses

A Smithville clinic that lost three Tuesday slots does not need another booking widget. It needs the text that actually went out, in a currency it can read, without buying a staff-rota product or a US “review + SMS” bundle. US reminder blogs skip CAD vs USD and treat TCPA as if it were CASL.

This comparison is four public cards that actually print a reminder story: Jane (Victoria clinic software; SMS on Practice/Thrive, official list in USD), Square Appointments (Canada appointments page in CAD; text and email reminders on Free), Calendly (USD calendar; automated reminders on Standard+; Canada SMS is 0 credits), and SimpleTexting (USD SMS inbox — not a calendar). Appointment-reminder prices checked against public vendor pages, 6 September 2026. Buttons are official marketing URLs, not affiliate trackers.

Who this page is for

• A Canadian clinic or treatment room that already books in Jane and needs to know SMS is not on Balance.
• A salon or studio on Square Canada that was about to buy a second SMS product for reminders Free already includes.
• A coach on Calendly who wants the official Canada SMS-credit rule, not a US blog’s per-text guess.
• A shop that needs two-way SMS without a clinic chart — and will accept a USD SimpleTexting bill plus CASL.
• Not a plumber buying Jobber for dispatch. Not a kitchen manager buying 7shifts. Not legal advice on CASL or college messaging rules.

Snapshot (public pages, 6 September 2026)

Jane — clinic SMS, but not on Balance

Official jane.app/pricing (6 September 2026): USD $54/month (Balance), USD $79/month (Practice), USD $99/month (Thrive). Practice and Thrive list “Unlimited, free SMS* Appointment Reminders.” Official FAQ: SMS availability varies by region. Balance is email reminders only on the public communications table. Communications table: email confirmation and unlimited email reminders on Balance, Practice, and Thrive. Thrive lists scheduled return-visit reminders. Practice does not. Jane’s official pricing page lists Balance / Practice / Thrive at USD $54 / $79 / $99. Canadian blogs often quote the same numbers as CAD — confirm the currency at checkout; this page does not treat those blog figures as an official CAD list. Source: https://jane.app/pricing.

Jane is the usual Canadian allied-health stack — booking, charting, then the reminder. Do not buy it as a cheap SMS pipe. If you only need the text, you are paying for a clinic product. If you already live in Jane, Practice is the SMS floor, not a third-party blaster. The public calendar and deposit comparison still sits on online booking; the clinic-vs-calendar shortlist is scheduling.

Square Appointments — CAD, reminders on Free

Official squareup.com/ca/en/appointments/pricing (6 September 2026): Official squareup.com/ca/en/appointments/pricing: Free $0/month for one location; Plus $35/month per location; Premium $85/month per location. Those dollars sit on the Canada appointments host next to Interac — treat as CAD and confirm GST/HST at checkout. The same pricing table lists “Text and email reminder notifications” as included on Free, Plus, and Premium. Square Assistant (clients confirm, reschedule, or cancel by text) is also listed on all three. “Text and email confirmation notifications,” custom text notifications, and cancellation policy / fees start on Plus. Free is reminders, not the confirmation-request or no-show-fee stack. Source: https://squareup.com/ca/en/appointments/pricing.

Official Canada Help “Confirmations and Reminders”: messages are transactional only; marketing and promotional language will be blocked. Delivery is email, SMS, or both from Appointments → Communications. Source: https://squareup.com/help/ca/en/article/6729-customer-confirmations-with-square-appointments. That is the opposite of buying SimpleTexting to market a blowout. If you already take Square cards in Canada, turn the reminder toggle on before you add another SMS bill. Cancellation fees and confirmation requests are Plus, not Free. Interac and CAD payouts are the same Square Canada table as the booking and POS guides — Interac 0.75% + 7¢ Interac debit chip/PIN/tap (Square CA appointments pricing).

Calendly — USD calendar, Canada texts cost 0 credits

Official calendly.com/pricing and Help (6 September 2026): Official calendly.com/pricing: “Automate meeting reminders” starts on Standard (US$10/seat/month billed yearly) and Teams (US$16/seat/month billed yearly). The Free card does not list automated reminders. Official Help “SMS credit limits” (updated 20 August 2026): non-Enterprise plans get 250 SMS credits per seat per month; Enterprise gets 1,000. Credits reset on the 1st of each month at 12 a.m. UTC. At 100% usage, texts stop and Calendly sends email instead. Official credit tiers: Canada and the United States are Tier 0 — 0 credits per message. Other countries cost 1, 3, or 9 credits. A Canadian clinic texting Canadian mobiles does not burn the 250-credit pot on that table — the pot still exists for other destinations. Official Help “How to send text messages with Automations” (updated 1 September 2026): SMS goes through Twilio; messages come from random U.S. numbers; invitee replies are not delivered or monitored; invitees must opt in; some carriers outside the U.S. may block messages; 180-character limit. Sources: https://calendly.com/pricing; https://calendly.com/help/sms-credit-limits; https://calendly.com/help/how-to-send-text-messages-with-automations.

Calendly is still a hold, not a till. Calendar booking — not an Interac till. Do not treat Calendly as card-present Interac. The reminder workflow is why coaches stay on Standard. The public booking-widget comparison — deposits, GST/HST on the slot — is online booking. The number on the truck is VoIP / business phone; Calendly’s Twilio sender is a random U.S. long code, not your Canadian DID.

SimpleTexting — USD SMS inbox, not a booking tool

Official simpletexting.com/pricing/ (6 September 2026): Public estimator: 500 credits at $29 plus a $10 local number = $39.00/month, or billed yearly at $398.40, plus a $4 one-time carrier registration. Extra credits on that example are 5.5¢ each. Local number is $10/month (same-day). Toll-free is offered as the other number type on the same form. Dedicated short code is a third picker. Additional numbers $10/month each. Additional teammates $20/user/month (three users included). Official FAQ on that page: carrier fees are passed through, not marked up — “approximately $0.0025 per message in the United States and $0.0068 in Canada.” Mass texting, two-way messaging, free inbound SMS, auto-replies and drip campaigns, MMS at 3 credits, API, unlimited contacts. Incoming SMS is free; incoming MMS is 1 credit. SMS is 160 characters / 1 credit; extended messages up to 306 characters cost 2 credits. No contracts on the marketing page. 30-day refund if you do not love the platform. Nonprofit / church 15% off monthly plans. simpletexting.com/pricing/ states “All prices are in USD.” Do not reprint the $29 / $39 example as CAD. Source: https://simpletexting.com/pricing/.

This is an SMS inbox, not a clinic chart or a public booking widget. You still need a calendar. CASL still applies to commercial electronic messages — this page is not legal advice. Use this when the calendar already exists and you need two-way texts, drips, or a keyword join — not when you still lack a bookable slot. A marketing blast is not a Square transactional reminder. CASL is yours: CRTC CASL FAQ.

A practical pick

1. Already on Square Canada for the chair: stay there. Free includes text and email reminders. Move to Plus for confirmation requests, custom SMS copy, and cancellation fees.
2. Allied-health clinic already in Jane, or about to be: Practice (USD $79) is the SMS floor. Confirm checkout currency. Do not treat a blog’s “CAD $79” as Jane’s list.
3. Consults and coaching on a calendar hold: Calendly Standard. Canada-bound SMS is 0 credits on the official tier table. Expect a U.S. sender ID, not your VoIP number.
4. Need two-way SMS or drips on top of a calendar you already own, and will label the bill USD: SimpleTexting. Confirm Canada carrier pass-through ($0.0068 on that FAQ) and CASL before you drip.
5. Still need clients to book themselves: online booking software.
6. Still need the clinic or field calendar: appointment scheduling.
7. Still need a Canadian number that rings: VoIP / business phone.
8. Staff shifts, not client no-shows: employee shift scheduling.
