Digital advertising has become one of the most important forces in Canadian election campaigns. The 2025 federal election made that clearer than ever. While traditional campaign tools still matter — leaders’ tours, debates, media coverage, lawn signs, ground game, and local candidates — the money now tells a powerful story. Canada’s major political parties are spending millions of dollars on advertising, and a growing share of that communication happens through digital channels. The latest financial returns from the 2025 federal election, reported by Stuart Benson in The Hill Times, offer one of the clearest looks yet at how much Canada’s major parties spent, where advertising fit into their overall budgets, and what that tells us about the future of political communication. This blog focuses specifically on federal election digital advertising in Canada: how spending evolved, what the 2025 numbers reveal, and why money alone does not win elections.
Federal Election Digital Advertising Canada: Why 2025 Was a Turning Point
The 2025 federal election was not just an expensive campaign. It was a digital-first campaign.
Parties were not simply buying television spots and sending direct mail. They were testing messages online, running rapid-response ads, targeting voters through social platforms, building audiences, and using digital channels to shape the daily political conversation.
According to The Hill Times, the Conservatives reported nearly $98.9 million in total expenses in 2025, while the Liberals reported more than $61.7 million. The Bloc Québécois reported just over $5 million, and the Green Party reported just under $3.5 million. The NDP’s financial statements were not available at the time of publication.
That means the four reporting parties spent nearly $169.7 million in 2025.
However, the advertising numbers are especially important.
The Conservatives spent $39.4 million on advertising over the year. The Liberals spent just over $21.6 million. During the writ period itself, the Conservatives spent $22.7 million on advertising, while the Liberals spent $21.3 million.
In other words, both major parties made advertising a central part of their campaign. Yet the final result also showed something every campaign should remember: advertising can amplify a narrative, but it cannot always create one.
How much did the Conservatives and Liberals spend on Advertising in 2025?
The headline number is striking.
The Conservatives spent almost $99 million overall in 2025. Of that, $39.4 million went to advertising.
The Liberals spent about $61.7 million overall. Of that, $21.6 million went to advertising.
During the official election campaign, both parties spent heavily on ads. The Conservatives spent $22.7 million on election-period advertising. The Liberals spent $21.3 million.
That means the two main national parties spent similar amounts on advertising during the writ period, even though the Conservatives spent far more across the full year.
2025 Federal Party Spending Snapshot
| Category | Conservatives | Liberals |
|---|---|---|
| Total 2025 expenses | $98.9M | $61.7M |
| Total annual advertising | $39.4M | $21.6M |
| Writ-period advertising | $22.7M | $21.3M |
| Estimated non-election advertising | $16.7M | ~$307K |
| Election expenses | $35.4M | $34.2M |
Pre-Writ Campaigning Matters
One of the most interesting findings from the 2025 spending data is what happened before the official campaign began.
According to the financial returns reported by The Hill Times, the Conservatives spent more than $16.7 million on advertising outside the writ period. The Liberals spent just under $307,000 on advertising outside the writ period.
That is a huge difference.
It shows how much modern campaigns now depend on pre-writ communication. The official election period may only last several weeks, but the campaign to define leaders, issues, and opponents starts much earlier.
This matters for federal campaigns. However, it also matters for provincial, municipal, and advocacy campaigns.
By the time the writ drops, many voters have already formed impressions. They have seen ads, watched clips, read headlines, and absorbed a narrative. Therefore, campaigns that wait until the official campaign period to start communicating are often already behind.
Pre-writ advertising allows parties to:
- define the opponent early
- introduce or reinforce a leader
- test messages before the campaign
- build audience pools
- collect first-party data
- establish narrative frames
- prepare supporters for donation and volunteer asks
However, it also creates risk. If the message does not match the public mood, more spending can simply amplify the wrong story.
How Much Did Parties Spend on Meta Ads?
Financial returns give us the broad advertising categories, but platform-level data helps show how campaign activity played out online.
During the 37-day writ period, Meta platforms saw more than $8 million in political ad spending, with the Liberals outspending the Conservatives by nearly $1 million on Facebook and Instagram ads.
That matters because Meta remains one of the most important political advertising platforms in Canada. It gives campaigns reach, speed, targeting, video distribution, retargeting, and real-time creative testing.
The spending patterns also show that digital advertising is not just about total budget. It is about timing and momentum.
According to reporting from The Hill Times, in the week before the writ period — March 16 to 22, 2025 — the Conservatives spent more than $563,000 on Meta ads, compared to about $250,000 by the Liberals. Then, on March 23, the day the election officially began, the Liberals spent $118,922 on Facebook and Instagram advertising across their official party and leader accounts, while the Conservatives spent $8,354 across their official accounts.
That one-day reversal is fascinating.
It suggests that digital advertising is no longer just about who spends the most across a full year. Campaigns also need to understand when to surge, when to test, when to defend, and when to define the ballot question.
For campaign teams, Meta spending should be reviewed through several lenses:
- total spend
- daily pacing
- creative volume
- audience targeting
- message themes
- engagement quality
- conversion goals
- opponent activity
In 2025, Meta was not just another ad platform. It was a real-time campaign battlefield.
Why More Advertising Did Not Automatically Mean Victory
The 2025 election offers one of the clearest Canadian examples of a major campaign truth:
Money helps. But money does not replace narrative.
The Conservatives spent far more over the year. They raised record-breaking money. They invested heavily in advertising. Yet the Liberals won the election.
Former Liberal PMO staffer and pollster Dan Arnold told The Hill Times that the Conservatives’ spending demonstrated “the limits of what money can buy in politics.” His broader point was that a stronger public narrative can overpower even a major advertising investment.
That is the central lesson for political digital advertising in Canada.
Digital ads work best when they amplify a message that already feels relevant, credible, and timely. If voters are focused on a different story, a campaign can spend millions and still struggle to move public opinion.
In 2025, the Liberal narrative around Mark Carney and his positioning in relation to U.S. President Donald Trump’s annexation and tariff threats became a defining story. That narrative appeared to capture attention in a way that paid advertising alone could not overcome.
As Harneet Singh, Managing Principal of EOK Consults, puts it:
“Digital advertising is incredibly powerful, but only when it amplifies the right story. Campaigns do not win because they spend more. They win when the message, timing, targeting, and public mood work together.”
That should be the takeaway for every serious campaign.
Five Digital Advertising Trends from the 2025 Federal Election
The 2025 federal election gives us more than spending numbers. It shows where Canadian political advertising is heading.
1. Digital Advertising Is Now Core Campaign Infrastructure
Digital is no longer a side channel.
It shapes message testing, rapid response, fundraising, volunteer recruitment, and voter persuasion. Campaigns are not just using digital to push out content. They are using it to decide what content should be created in the first place.
This is a major shift.
In older campaigns, digital was often treated as a megaphone. A communications team would create a message, and digital teams would distribute it.
Now, digital performance helps shape strategy. If an issue ad performs well in one region, it may influence earned media, email fundraising, leader remarks, and local candidate content.
Campaigns that still treat digital as an afterthought are working with an outdated model.
2. Pre-Writ Advertising Is Becoming Its Own Campaign
The Conservatives’ $16.7 million in non-election advertising shows how important the pre-writ period has become.
Before the official campaign, parties can shape impressions, test attacks, define issues, and prepare the ground for the election. This is especially powerful when the governing party is facing pressure or when an opposition party wants to frame the ballot question early.
However, pre-writ spending must be strategic.
If a campaign spends heavily too early, it can create fatigue. If the message is too negative, it can backfire. If the public environment changes, months of messaging can become less relevant.
Therefore, the best campaigns use pre-writ digital advertising to learn, not just to broadcast.
3. Meta Remains a Major Political Battlefield
Despite constant changes to platforms and targeting rules, Meta remains one of the most important digital advertising environments in Canadian politics.
Facebook and Instagram offer campaigns:
- broad reach
- local targeting
- video distribution
- retargeting audiences
- creative testing
- fundraising and signup pathways
- issue-based segmentation
The 2025 numbers show that both major parties used Meta heavily around key moments.
However, Meta is also transparent in ways traditional advertising is not. Ads are visible in the Ad Library. Spend ranges can be tracked. Creative can be compared. Journalists, opponents, researchers, and voters can all see what parties are saying.
That transparency changes campaign behaviour.
Every Meta ad should be treated as public communication, not just targeted communication.
4. Narrative Still Beats Pure Targeting
Targeting matters. But targeting does not save a weak message.
Some campaigns obsess over audience segments while underinvesting in the story. Yet voters do not respond to targeting logic. They respond to relevance, emotion, credibility, and stakes.
The strongest political ads usually answer a simple question:
Why does this matter to me right now?
In 2025, the campaigns that cut through were not necessarily the ones with the biggest budgets. They were the ones that connected their message to the moment.
That is why digital advertising needs both data and political judgment.
5. First-Party Data Is Becoming More Valuable
As platform rules evolve and privacy expectations rise, campaigns cannot rely only on paid reach.
They need first-party data.
That includes:
- email lists
- SMS subscribers
- donors
- volunteers
- petition signups
- website visitors
- event RSVPs
- social media engagers
- issue survey respondents
Digital advertising helps build those audiences. Then, those audiences help campaigns communicate more efficiently later.
This is especially important for campaigns with limited budgets. A strong supporter list can reduce the need to constantly pay platforms for attention.
What the 2025 Federal Election Digital Advertising Spending Data Means for Future Canadian Elections
The 2025 federal election will influence how campaigns plan future races.
At the federal level, parties will continue investing heavily in online advertising, especially around leader definition, fundraising, and rapid response.
At the provincial level, digital will remain central in pre-campaign issue framing and local riding persuasion.
At the municipal level, the lesson is even more important. Municipal candidates rarely have national media coverage or large budgets. Therefore, targeted digital advertising can help them build name recognition and reach voters who may never attend a debate or answer a door knock.
This matters for upcoming municipal elections in Ontario, British Columbia, and Quebec.
Local campaigns should be paying close attention to the federal trend:
- start earlier
- build audience data
- use digital for message testing
- invest in video
- prepare rapid-response systems
- do not wait until the final month
Digital advertising is no longer just about spending money. It is about building campaign capacity.
Lessons for Municipal and Advocacy Campaigns
Although the 2025 data comes from federal parties, the lessons apply far beyond Parliament.
Start Before the Formal Campaign
If voters only hear from you during the official campaign, you are already late.
Early digital content helps build familiarity, trust, and audience pools.
Spend With a Strategy
Boosting random posts is not a strategy.
Every dollar should have a job: awareness, persuasion, fundraising, list growth, volunteer recruitment, or GOTV.
Match Message to Moment
A good ad in the wrong moment may fail. A simple ad in the right moment can move quickly.
Campaigns need to watch the public conversation and adapt.
Build Owned Audiences
Email, SMS, and supporter lists matter. Social platforms are useful, but campaigns should not rely entirely on rented audiences.
Measure What Matters
Likes and views are not enough.
Campaigns should track:
- cost per signup
- video retention
- landing page visits
- donation conversion
- volunteer leads
- audience growth
- persuasion signals
- turnout actions
That is how digital becomes a campaign advantage.
