The verdict in three sentences
A website without a maintenance retainer degrades within 6 to 12 months: security holes, outdated plugins, undetected outages. A retainer at CA$150-CA$800/month covers updates, backups, monitoring and small evolutions, for far less than the cost of a hack or an emergency rebuild. The right contract is judged on its SLA and response time, not just its price.
What does a retainer really cover, and at what price?
Not all retainers are equal. Here are the 2026 tiers in Toronto, in CA$/month.
| Tier | Price/month | What is included | Response time |
|---|---|---|---|
| Essential | CA$150 | Security updates, backups, monitoring | 72 business hours |
| Standard | CA$350 | + fixes, small evolutions 2 h/month | 24-48 h |
| Business | CA$550 | + evolutions 4 h/month, monthly report | 24 h |
| Premium | CA$800 | + 4 h SLA, on-call, priority | 4 business hours |
A standard brochure site runs well on Standard or Business; a revenue-critical site justifies Premium.
Hourly or retainer: which should you pick?
Hourly looks cheaper until the first outage. A retainer smooths the cost and guarantees responsiveness.
| Criterion | Hourly | Retainer |
|---|---|---|
| Apparent price | CA$90-140/h | CA$150-800/month |
| Automatic backups | Not included | Included |
| Uptime monitoring | No | Yes, 24/7 |
| Response time | Subject to availability | Guaranteed by SLA |
| Preventive updates | Billed separately | Included |
| Budget predictability | Low | High |
Over a year, a site left on hourly often costs more after a single major outage (restoration + lost business).
Mini case study
David, principal of a consulting firm in Toronto, had declined maintenance to save money. Eight months after launch, an un-updated plugin opens a hole: site defaced, down for 5 days. Emergency recovery costs him CA$1,200, plus a dozen missed appointments due to a broken contact form. A Standard retainer at CA$350/month, i.e. CA$4,200/year, would have prevented the incident and smoothed the budget. He now subscribes at the Business tier.

FAQ
Is maintenance really indispensable?
Yes. An un-updated CMS accumulates known vulnerabilities exploited automatically by bots. Without backups or monitoring, an outage can freeze the site for several days.
What is the difference between hosting and a retainer?
Hosting (CA$20-60/month) provides the server; the retainer maintains the application, fixes bugs and applies updates. The two are complementary, never equivalent.
What must the SLA guarantee?
A quantified response time (e.g. 4 h or 24 business hours), a target uptime (99.9 %) and a backup frequency. Without those figures in writing, the contract does not protect you.
Can you cancel a retainer easily?
Require a reasonable notice period (1 to 3 months) and a reversibility clause: recovery of backups and access. Avoid contracts that hold your data hostage.
How much to budget per year?
Between CA$1,800 (Essential) and CA$9,600 (Premium) per year. For most SMEs, the Standard tier at CA$4,200/year offers the best security/cost balance.
