Stop losing leads to missed calls. An Ontario operator's guide.

It's Tuesday at 11:47 AM. A homeowner in Aldershot calls your office because her water heater is making a noise. Your office manager is in the bathroom. Your apprentice is on a job. The phone rings five times and goes to a voicemail nobody's set up properly. The homeowner hangs up and calls the next plumber on the list. You will never know that call happened.

You don't have to live with that anymore. For $50 a month, you can fix it.

Let's do the math your office manager already knows in their gut. You get 10 calls a day. 2 of them miss. That's 10 a week. 500 a year. If your average job is worth $500, you're sitting on $250,000 of at-risk revenue annually — just from a phone nobody answers.

Even if only 20% of those missed callers would have converted, you're leaving $50,000 on the table. Setting up the fix costs $200–300 to build and $50–100/month to run. The math isn't close.

Here's the system, end to end:

• The phone rings. Your office is busy. Nobody picks up.
• Within 60 seconds, the caller's phone buzzes: “Hi — sorry we missed your call. Reply YES and we'll call you back within the hour, or call us at 905-XXX-XXXX.”
• If they reply YES, the message goes into a queue. Your office manager gets a notification.
• The caller's number, the time they called, and their response are written to your CRM automatically.
• If they don't reply in two hours, an optional second message goes out — softer, “just checking in.”

The first time we ran this for a Burlington trades company, they recovered 11 leads in the first week. Three became paid jobs. Two of those three turned into repeat customers within six months. The system paid for itself in 9 days.

You have a few options. All of them work. Picking depends on what you already use:

• Twilio. The infrastructure layer. Handles SMS sending and call routing. About $30/month for typical volume.
• Make.com (formerly Integromat). The automation layer. Listens for the missed call, triggers the SMS, updates your CRM. $9–29/month depending on usage.
• Zapier. Same idea as Make, slightly different pricing. Both fine.
• GoHighLevel. All-in-one platform — CRM, SMS, automation, everything bundled. About $97/month. Best fit if you don't have a CRM yet.

Trades

Plumbers, HVAC, electricians, roofers.

Calls come in while you're on a job. The competitor down the highway has someone at a desk. This levels the field — and most jobs go to whoever responds first.

Healthcare

Family clinics and dental practices.

Reception is on the other line. The patient hangs up. They book elsewhere. Auto-text recovers them — and the message itself sets the tone for the practice.

Real Estate

Realtors, mortgage brokers, insurance.

You're in showings. They're house-hunting at 8 PM. The text response means they don't go cold while you're with another client.

Is this compliant with CASL? Yes — transactional messages responding to a contact the user initiated are allowed without prior express consent. The caller called you. You're responding to theirinquiry. That's explicit implied consent under CASL section 10(9)(b). Keep the message limited to the matter they called about and you're fine.

What about TCPA / U.S. callers?If you're also taking calls from the U.S., be more conservative — use a one-time response only, no follow-up SMS, and always include an opt-out (“Reply STOP to opt out”). U.S. rules are stricter than Canadian ones.

Can I build this myself? Yes. Zapier and Make.com have templates. It's a 2–3 hour job if you're comfortable with automation tools. If you'd rather we build it for you, it's a typical first-project in a Build Sprint.

What if the caller doesn't respond to the SMS? You still have their number and the time they called. Your office manager calls them back. You're still strictly ahead of the version of your business where the call just vanished.

What if the caller is a robocall or wrong number? The system tracks reply rates. Real callers reply about 35% of the time. Robocalls almost never do. After a month you can see the pattern and tune the system to ignore numbers that match known spam lists.

What if my office uses a VoIP system already? Most modern phone systems (RingCentral, Dialpad, GoToConnect, even Google Voice business accounts) have webhooks for missed calls. The integration is usually 30 minutes of work, not a week.

If missed calls are the bleed you already know about, this is the first project we'd ship in a Build Sprint. Want to know whether it's the right first project for your business? Book a 30-minute session at the bottom and we'll work through it together.
