Facebook Advertising in 2021 Canadian Federal Elections: 4 Facts You Must Know

social media in Canadian politics

Over the last few years, political digital marketing has become more and more prevalent in Canada. In terms of social media platforms where political advertising is permitted, Facebook and its platforms have a lopsided share. Ever since new political advertising legislation in Canada mandating digital archives and other reforms was enacted, many platforms such as Twitter and TikTok responded by opting out of participation. Due to additional public pressure, especially after the 2016 US Elections, these platforms went a step further and banned all paid political advertising altogether. Therefore, Facebook advertising, particularly when guided by a digital and social media marketing agency for political campaigns, presented an ideal opportunity for Canadian political parties and candidates aiming to woo the population online. Interested in seeing how this impacted the recently concluded Canadian federal elections? Here are four facts regarding Facebook advertising in the 2021 elections that you must know.

Total spending by all parties combined

In terms of digital marketing for political campaigns, parties and candidates did not hesitate to spend millions of dollars. As per data publicly available, the total budget for Facebook advertising for all parties combined was more than C$6.7 million between June 17th and September 14th, 2021. This doesn’t include the millions of dollars spent combined by all candidates and third-party advertisers. For comparison, the amount spent by the three parties on their entire digital campaign in 2019 totaled around C$9.7 million. As can be seen from these statistics, politicians are increasingly establishing an online presence on a continuous basis. Given the high engagement levels and measurable return-on-investment of digital platforms, we might reasonably assume that those numbers will increase in future elections. 

Number of Ads placed on Facebook by all parties

It is important to note that in 2021, the number of ads made on Facebook alone varied considerably among the three major parties. Based on information from Facebook’s Ad Library, the Liberals made over 12,000 Facebook advertisements during the last election. Comparatively, the Conservative Party ran only 1243 advertisements, while the New Democratic Party produced 1148 advertisements. As shown by the statistics, Liberals are the ones putting up more Facebook ads than any other party. In total, the Liberal Party placed five times as many advertisements as the New Democrats and the Conservatives combined. This speaks volumes (pun intended) about their sophisticated digital media strategy and resourceful social media team.

The Liberal Party of Canada outspent its rivals

Each of the three leading parties in Canada spent a proportionate amount on their advertising relative to the number of advertisements they ran. In the period between June 17, 2021 and September 14, 2021, the Liberal Party spent a staggering amount of $2.3 million. Comparatively, the Conservative Party had spent C$1.4 million during the same period while the New Democratic Party spent C$1.1 million. Taking these numbers into account, there are two important conclusions that can be drawn. First, the Liberal Party spent more on Facebook advertising than the Conservatives and NDP combined. Second, they spent twice as much as the Conservative Party which won the popular vote but still lost key ridings and their chance to govern.

A/B testing and dynamic advertising: The winning formula

In addition to a difference in the number of ads and money spent, there was also a key difference in the number of ad variations. While the Conservatives published over a thousand different ads on Facebook, the Liberals generated more than 5,000, and the NDP conducted approximately 750. This data demonstrates that the Liberals had a more sophisticated marketing strategy than their competitors. Having a variety of content layouts and messages indicates that the Liberal team was proactively responding to online engagement, voter preferences and demographic targeting. This dynamic digital advertising phenomenon clearly stands out as the winning formula employed by the Liberal Party of Canada, possibly enhanced through a digital and social media marketing agency for political campaigns, to retain power for the third time. There was also an indication of this trend during the previous federal elections in 2019, where the Liberals ran 7500 ad variations, while the Conservatives ran about a thousand ad variations between June and October.


During the 2021 Federal Elections, it was the Liberals who clearly dominated Facebook advertising and digital marketing when compared with its national counterparts. The data does not only relate to the amount of money spent on Facebook, but also the number of advertisements and variations on the ads.
