Ask a few Canadian business owners about the last marketing agency they hired, and you'll hear some version of the same story. Nothing went terribly wrong. The reports showed up every month, and traffic crept up a little. But a year later, nobody could point to many new customers, and renewing the contract felt more like habit than a decision.
That habit costs more now. Digital is projected to account for 80.1% of all media ad spending in Canada in 2026, so most of what you spend on marketing ends up passing through somebody's hands, probably an agency's.
So who do you trust with it? Search for Best Digital Marketing Agency Canada and you'll get pages of firms calling themselves exactly that. Many are fine. Some are great. A few you'll want to avoid. These are the eight things worth checking before you sign anything.
1. Watch What They Ask You
The first call says a lot. If the agency spends most of it on their awards and client logos, it's a sales call, not a discovery call.
A team worth hiring will want to know your average order value, how long your sales cycle runs, and which products actually make money (not just which ones sell). They might ask why you left your last agency. Some of these questions are a little awkward to answer, and that's a good sign. If an agency doesn't understand what a customer is worth to you, it can't tell you what a lead is worth either, and everything after that is guesswork.
2. Check the Proof Yourself
Case studies are easy to dress up. "Traffic up 300%" sounds great until you find out it went from 200 visits a month to 800.
So dig a bit. Look for named clients, real numbers, and actual timelines. Read their reviews on Clutch and Google, especially the middling ones, since that's usually where the honest detail is. Then ask for a couple of references in your industry and phone them. Skip "were you happy?" Ask what went sideways at some point, and what the agency did about it.
3. Do They Know Canada, or Just Marketing?
Plenty of agencies run Canadian campaigns on a playbook built for the U.S. Usually you won't notice. Sometimes it gets expensive.
Email is the obvious example. Canada's Anti-Spam Legislation (CASL) covers nearly every commercial email or text you send, and fines can reach $10 million per violation for an organization. Your agency should know how CASL consent works without having to look it up.
Then there's Quebec. If you sell there, Bill 96 requires your website to be available in French. On ads and signage, French now has to be "markedly predominant" over any other language. An agency that knows the market will raise this before you do. It'll also have French copywriters on hand, instead of running English ads through a translation tool and hoping nobody in Montreal notices. (They will.)
4. Ask About AI Search
This one is newer, and a lot of agencies are still working it out.
Google's AI Overviews now sit above the regular results on a big share of searches, and they're pulling clicks away. One Ahrefs study found that when an AI Overview appears, top-ranking pages now get a 58% lower clickthrough rate on average, up from 34.5% just eight months earlier. Ranking first still matters. It just doesn't deliver what it used to.
Ask each agency how they track whether your brand shows up in AI Overviews, ChatGPT, Gemini or Perplexity, and what they'd change to improve it. Solid SEO Services in 2026 still cover the basics: site health, content people actually want to read, and links from sites that matter. They should also have a clear answer on AI visibility. Be wary of anyone treating it as a shiny upsell, and just as wary of anyone who shrugs it off.
5. Find Out Who's Actually on Your Account
This happens a lot. The senior strategist who impressed you in the pitch disappears after kickoff, and your account lands with a junior coordinator juggling 25 other clients.
Ask who'll do the work week to week, and how many accounts that person manages. Ask plainly whether any of the work gets outsourced or white-labelled. Outsourcing isn't automatically bad, but you should hear about it before you sign, not after.
Being close by also helps more than people expect. Zoom is fine for check-ins, but planning sessions tend to go better face to face. If you're in the GTA, a Digital Marketing Agency Toronto team can come in for those meetings, and it'll already know a local market that's crowded and expensive to compete in.
6. Reports That Point to Money
Rankings and traffic charts are nice to look at, but they aren't the point. You want reporting that connects a campaign to a lead and a lead to a sale. Ideally it pulls from your CRM, so you can see which ads brought in paying customers and which only brought in clicks.
One more thing, and it's important. Your Google Ads, GA4, Search Console and Meta accounts should be owned by your business. The agency gets access, not ownership. If it builds everything under its own logins, leaving later can mean losing years of data.
7. Clear Pricing, Fair Contracts
You should know exactly what your monthly fee covers: the hours, the deliverables, and who handles what. When the retainer is vague, the results usually are too.
On contracts, some patience is reasonable. SEO often takes four to twelve months to show up in the numbers, so a minimum term makes sense. A year-long lock-in with no way out doesn't. A fair notice period is what you're looking for.
And if someone promises you the #1 spot on Google, thank them for their time and move on. Nobody can guarantee that, and agencies that know what they're doing won't try.
8. Ask What They'd Skip
This question tells you a lot: "What wouldn't you recommend for us?"
An agency that sells twelve services has every reason to recommend all twelve. The good ones will tell you a B2B equipment supplier probably doesn't need TikTok, or that your website needs work before you put more money into Google Ads. If an agency can't name a single thing you should skip, that's worth noting.
Before You Sign
Pick three agencies and send them all the same brief. Then compare how they think, not how slick the proposals look. Who asked the best questions? Who disagreed with you about something? Who explained their reasoning without hiding behind jargon?
That's probably your agency. The one willing to push back before you've paid them anything is usually the one that'll be honest with you later, too.
