What a marketing agency retainer costs per month in Canada, and the six lines that set the figure

A Canadian agency retainer is not a market rate you can look up, it is the output of six decisions, and a buyer who settles those six in writing gets three comparable quotes instead of three incomparable ones. The six are the language architecture, the number of provinces that genuinely need their own pages, who owns compliance, how many disciplines run at once, who the named senior owner is and how many hours they actually have, and whether media spend is inside or outside the fee. Settle all six, send the same scope to three firms, and the spread between their quotes becomes informative rather than confusing. Ask three firms before the six are settled and you are comparing three different products.

The six lines, and what each does to the figure

Decision	Effect on the monthly figure	How to settle it
Language architecture	The largest single multiplier. Bilingual is close to two programmes	One domain with French in a folder, a subdomain, a separate French property, or English only, decided in writing
Provinces needing their own pages	Each genuine province page is scope. Most decks propose more than the business needs	Only where you have a presence or can genuinely serve, which is usually fewer than proposed
Who owns compliance	A real line, not an overhead. CASL for outreach and Quebec language for publishing	Name the owner of each in the agreement
Disciplines running at once	Each concurrent discipline adds coordination, which is what an agency's premium buys	Count them. One means a freelancer may be the better buy
Named senior owner and real hours	The single biggest driver of quality per dollar	Ask for hours a month by name, and what happens when they leave
Media inside or outside the fee	A percentage of spend model and a flat fee behave differently as you grow	Ask for both, in writing, with the crossover point

Currency and tax, because the quote is not the invoice

Three Canadian specifics that change what you actually pay. Ask whether the fee is stated in Canadian or US dollars, because a US dollar retainer means your monthly cost moves with the exchange rate even when the scope does not. Ask which sales tax applies, because GST applies federally, HST in the harmonised provinces, PST in British Columbia, Saskatchewan and Manitoba, and QST in Quebec, and a non resident supplier is generally required to register and collect. And ask whether any third party software licences are billed through the agency or direct, since those carry their own currency and tax treatment.

Write all three into the comparison sheet beside the figure. A quote without a currency and a tax treatment is not yet a price.

Why we do not publish a Canadian range

A single number presented as the Canadian retainer rate would be false for most readers, because the six decisions above move the figure by multiples rather than by percentages. What is honest and more useful is the method: settle the six, send one scope to three firms, and compare. The spread you receive is your market rate, it is current, and it is specific to your scope, which no published range can be. We also do not reproduce other suppliers' price tables, because a competitor price copied today becomes a false statement about somebody else's business within weeks and an undated figure in a comparison is the detail a reader and an engine both have reason to discount.

What the engines told Canadian buyers who asked about cost

On 22 October 2026 we put a 198 question Canadian buyer bank in 33 batches to the ChatGPT and Gemini product surfaces through a data provider. Canada was named inside the text of every question, because the provider accepts gl, hl and location parameters and ignores all three. Batch 33 names us in the question and measures a ceiling, so it is excluded from every figure below. Sixty four blind readings, 32 per engine, 2,992 citation URLs across 974 distinct hosts.

On pricing and contract questions the engines answered mostly with ranges and frameworks rather than with suppliers, and across the whole Canadian set 33 of the 64 readings named no supplier at all. Where names did appear, software took 48 namings, led by Semrush in 16 readings, HubSpot in 12 and Ahrefs in 9, and six Canadian agencies were named 21 times, with Major Tom in 8 readings and Konstruct in 6. So an assistant is currently a poor instrument for finding out what a Canadian retainer costs, and the answer a buyer gets is a range with no scope attached to it, which is exactly the thing this page argues against.

The engines also differed. Gemini named a rival in 18 of its 32 Canadian readings against ChatGPT's 13, and ChatGPT ran a live web search on all 32 of its readings against Gemini's 20 of 32. The two are reported separately because averaging them would hide both differences.

The ten day process that produces three comparable quotes

• Days 1 to 3. Write the six decisions down and get them agreed internally. This is the whole job.
• Day 4. Send the identical scope to three firms with a reply date and a request for the fee in Canadian dollars with tax treatment stated.
• Days 5 to 8. Compare on the six lines rather than on the total. A cheaper quote with fewer disciplines is not cheaper.
• Day 9. One call each with the same agenda and the same scoring sheet.
• Day 10. Decide, and record which of the six decisions each firm interpreted differently, because that is where the overrun will come from.

If the language and province decisions are the ones holding you up, they are worked through in detail in three decisions that set the scope and the price. If your scope is one city rather than the country, the decision order that saves money in Toronto is in the decisions in the order that saves money.

Questions Canadian buyers ask about agency retainers

Why will you not give me a number?

Because the six decisions above move the figure by multiples, so a single Canadian rate would be wrong for most readers. The method produces a number specific to your scope in ten days.

Should the retainer include media spend?

Ask for both models and the crossover point. A percentage of spend aligns the agency with growth and misaligns it with efficiency. A flat fee does the opposite. Which is better depends on whether your spend is about to rise.

Is a Canadian firm more expensive than an overseas one?

On fee alone, usually. After your own coordination hours and a Canadian compliance reviewer are priced in, the gap narrows considerably.

What is the minimum term I should accept?

Long enough for the work to show and short enough to leave. Three to six months with a thirty day exit and a defined handover is a reasonable Canadian default.

Who should own CASL compliance?

Whoever sends the messages, named in the agreement, with consent records produced on request and handed over at exit. It is the clause most often missing.

The one reporting line to write into the retainer

Whatever you agree, the monthly report will cover rankings, traffic and media. On 22 October 2026 our Canadian readings named nobody at all in 33 of 64 cases, which is a queue most Canadian retainers do not report on. AI Knows Us reads ChatGPT, Gemini, Perplexity, Claude and Google AI Overviews with Canada named inside the question, reports each engine separately with its denominator, and keeps the raw answer text so the agency's figure can be checked against something you hold. Outside the United States and the United Kingdom the cheapest plan that reads all five engines is Growth at 199 dollars a month with 100 buyer questions watched, read on aiknowsus.com/pricing and aiknowsus.com/llms.txt on 22 October 2026.
