The Short Answer
A realistic starting budget for Google Ads in the Ottawa legal market is $800 to $2,500+ per month, somewhat lower on average than Toronto's more saturated market, but still a real, sustained commitment rather than a token spend. Personal injury and family law see the highest per-click costs given case value and competition; employment law targeting federal-sector terms specifically can be less contested simply because fewer firms are bidding on those precise phrases yet. PPC is rented visibility — the moment you stop paying, the traffic stops.
Why Per-Click Costs Vary So Much by Practice Area
Google Ads runs on an auction — the more firms bidding on a keyword, the higher the cost per click climbs. Personal injury remains consistently expensive to advertise in Ottawa because the potential case value supports aggressive bidding. This is also why how much an Ottawa firm should budget for marketing overall needs to account for practice-area-specific PPC costs rather than a flat number.
Niche, Ottawa-specific terms — federal-employment severance questions, bilingual French-language ad targeting — currently see far less competition simply because so few firms are bidding on them yet. This is one of the reasons a smart PPC strategy also considers alternatives like Facebook and Meta ads, which use a different bidding dynamic to reach some of the same audience.
How PPC Fits Into an Ottawa Firm's Broader Marketing Mix
PPC is fast — you can be visible for a target search within a day of launching a campaign. It sits alongside paid presence on the right social media platforms as part of a full paid-visibility mix. But PPC is also the most direct place an Ottawa firm can overspend without a return, which is exactly why tracking marketing ROI properly matters more for PPC than almost any other channel.
PPC also carries specific Law Society of Ontario advertising compliance considerations, whether the campaign is running in English or French. See the Law Society of Ontario's advertising rules for Ottawa firms before writing ad copy, not after a campaign is already live.
PPC buys attention instantly. It doesn't buy trust the way organic authority does — which is exactly why the firms that win long-term treat PPC as one channel in a mix, not the whole strategy.

Running PPC Yourself vs. Hiring It Out
Google Ads has a genuine learning curve — poorly structured campaigns and un-optimized landing pages routinely waste a meaningful share of ad spend. This is one of the biggest marketing mistakes Ottawa law firms make — launching PPC without the expertise to manage it properly, then concluding "PPC doesn't work" when the real issue was execution.
Whether to manage this in-house or bring in outside help is the same decision covered more broadly in hiring a marketing agency versus building an in-house team.
Where This Fits Into the Bigger Picture
This question doesn't exist in isolation. It connects directly to Are Facebook and Meta Ads Worth It for an Ottawa Law Firm?, How Do I Build a Referral Program for My Ottawa Law Firm?, and What's the Difference Between Branding and Marketing for an Ottawa Law Firm? — three pieces of the same underlying decision a Ottawa firm has to make. Once those are settled, the natural next questions are How Much Should an Ottawa Law Firm Spend on Marketing?, How Do I Track Marketing ROI for My Ottawa Law Firm?, What Are the Law Society of Ontario's Advertising Rules for Ottawa Firms?, and Which Social Media Platforms Should an Ottawa Law Firm Actually Use?.
