The verdict in three sentences
For a Montreal SME without in-house IT, a WordPress maintenance retainer costs USD 90 to 165 per month for basic security and USD 275 to 660 once you add enhancements and monitoring (CAD 120 to 900). The right selection criterion is the guaranteed recovery time (4 to 24 hours), far more than the sticker price. A single uncovered hack costs on average USD 3,300 to 8,800, which equals two to five years of the most complete retainer.
What each retainer level covers in 2026
Agencies and freelancers in Montreal, Laval and Longueuil usually offer three tiers. The difference lies in update frequency, backup depth and contractual response time.
| Level | Monthly fee (USD) | Updates | Backups | Guaranteed recovery | Included enhancements |
|---|---|---|---|---|---|
| Essential | 90 to 165 | Monthly | Daily, 14 days | 24 business hours | 0 h |
| Comfort | 200 to 330 | Weekly | Daily, 30 days, off-site | 8 business hours | 2 h |
| Pro | 330 to 495 | Weekly + critical patches within 24 h | Hourly, 30 days | 4 business hours | 4 h |
| Premium | 495 to 660 | Continuous, staging environment | Hourly, 90 days | 4 h, 7 days a week | 6 h |
| Ad hoc (no contract) | 80 to 105 per hour | None | None | No commitment | Billed |
The Essential tier is enough for a 10-page brochure site with few plugins. As soon as the site carries a quote form, a client area or a store, the Comfort tier becomes the reasonable minimum: a form that is down for a week can lose 5 to 15 quote requests.
The real cost of an unmaintained site
WordPress powers about 43 % of websites worldwide, making it the number one target for bots. Most intrusions come through an outdated plugin, not the CMS core.
| Incident | Estimated annual probability (unmaintained site) | Clean-up cost (USD) | Indirect cost |
|---|---|---|---|
| Vulnerable plugin exploited | 15 to 25 % | 1,650 to 4,400 | Google blacklist, 2 to 6 weeks of lost traffic |
| SEO spam injection | 10 to 20 % | 1,100 to 3,300 | Search rankings down 30 to 70 % |
| Ransomware or database wipe | 3 to 5 % | 3,300 to 8,800 | Site offline 3 to 10 days |
| Breaking PHP update | 20 to 30 % | 440 to 1,320 | Forms not working |
| Expired SSL certificate | 5 to 10 % | 165 to 330 | Browser warning, bounce rate doubled |
| Privacy breach notification (Law 25) | 1 to 2 % | 2,200 to 11,000 in advisory fees | Regulatory sanction risk |
These 2026 estimates show that a USD 165 monthly retainer, about USD 2,000 a year, pays for itself with the first incident avoided. The contract should also state who notifies the Commission d'accès à l'information under Quebec's Law 25 if personal data leaks.
Clauses to check before signing
Read the contract with five points in mind. First, the recovery time must be written in plain terms, with a penalty or credit if the commitment is missed. Second, backups must be stored outside the main host, otherwise a datacenter outage takes both the site and its copies. Third, can unused enhancement hours roll over? The best contracts allow a three-month carry-over. Fourth, uptime monitoring should test the site every 1 to 5 minutes and alert by SMS. Finally, check reversibility: admin access, FTP access and backup exports belong to you, and termination requires one to three months' notice at most.

Claire runs a 12-person energy engineering consultancy in Montreal and receives about 25 quote requests a month through her WordPress site. Her conversion rate is 20 % and the average engagement is worth USD 4,400. A two-week form outage would therefore cost about 12 requests, 2.4 engagements and nearly USD 10,500 in revenue. She chooses the Pro tier at USD 385 per month, about USD 4,600 a year, with 4-hour recovery and 4 monthly enhancement hours she uses to add one page per quarter. A single avoided incident covers more than two years of the contract.
FAQ
Can I maintain a WordPress site myself?
Yes for a simple brochure site, provided you spend 2 to 3 hours a month and test each update on a copy. Without staging, a failed update can cost USD 440 to 1,320 to repair.
Is hosting included in the maintenance retainer?
Rarely in the Essential tier. Budget an extra USD 11 to 45 per month for shared hosting or a Canadian VPS, though some Premium tiers include it.
What happens if my site is hacked despite the contract?
The provider restores the last clean backup within the guaranteed time, 4 to 24 hours depending on the tier, at no extra charge. Check that malware clean-up is included, as it is sometimes billed separately at USD 330 to 880.
How many enhancement hours should I plan for?
An SME that publishes one news item a month and adjusts its offers uses 2 to 4 hours monthly. Beyond 6 hours, a dedicated application maintenance contract becomes cheaper.
What commitment length is normal?
Twelve months with automatic renewal and one month's notice is the norm in Montreal in 2026. Be wary of 36-month commitments with no exit clause.
