As of October 1, 2024, a new 2.5% tax applies to all advertising spend through Google Ads and DV360 in Canada. This measure directly affects all businesses that use Google as an acquisition lever, increasing the real cost of campaigns running in Canada.
At Bofu Marketing Agency , our role is to anticipate these changes and optimize your investments so that every dollar continues to generate maximum value.
Updated on July 1, 2025, this Google tax will cease.
Effective July 1, 2025, Google will stop charging the 2.5% Digital Services Tax (DST) fee on ads served in Canada, in line with the Canadian government's commitment to repeal this tax. Fees already charged will be refunded once the repeal is formalized through legislation. Display & Video 360 users may still see DST fees in their reports until July 31, 2025, but these fees will not be included on invoices or billed. Applicable local taxes, such as sales tax, GST, QST, or VAT, will continue to apply as normal.
A tax resulting from new Canadian legislation
This measure stems from the Digital Services Tax Act , adopted in July 2024 by the federal government. It aims to ensure that large technology companies that generate significant revenue in Canada, without necessarily being based there, contribute fairly. Initially set at 3% of revenue generated by Canadian users, this legislation targets giants such as Google, Meta, Amazon, and Apple.
Google responded by passing this tax on to its customers. Since October, a 2.5% tax has been automatically added to all ad impressions served in Canada, regardless of the advertiser's geographic origin.

What this means in concrete terms for your business
This cost increase applies without any direct correlation to your campaign performance . In other words, your results remain the same, but your bills increase. For example, a business that spends $10,000 per month on Google advertising will now have to pay about $250 more each month—or $3,000 per year—just because of this tax.
Even if this amount seems minor in a growth context, it has a direct impact on your profit margins and your ROAS (Return on Ad Spend) .
Another important point: this tax is not a traditional GST or QST. It is an additional fee imposed by Google , which generally cannot be recovered by businesses. It is therefore essential to include it in your budget projections as a net expense.
Foreign companies also concerned
The tax applies to all ads served in Canada , even if the business is located outside the country. Therefore, a French, American, or Mexican business targeting Canadian consumers through Google Ads will also be subject to this tax.
How to adapt to this new reality
In a context where margins are tightening and every dollar counts, it is crucial to rigorously review your media strategies. Here are some concrete courses of action:
1. Re-evaluate your advertising budgets
Factor this tax into your monthly and annual projections to avoid end-of-period variances. If you manage multiple channels, adjust your allocations to maintain the overall effectiveness of your campaigns.
2. Optimize your existing campaigns
Refine your campaign structures, audiences, keywords, and bidding strategies. The goal: generate more results for every dollar invested. This tax emphasizes the importance of precise, profitability-driven management.
3. Diversify your acquisition channels
Don't rely solely on Google Ads. Explore other platforms like Meta Ads, LinkedIn, TikTok, Pinterest, or even programmatic placements tailored to your audience. A well-balanced omnichannel strategy helps reduce the pressure on any one lever.
