Emigration in Canada and “Brain Drain”: What the Data Shows

Overview

Canada is both a major destination for immigrants and a country with measurable outflows of residents and citizens to other countries. Several recent datasets make it possible to describe:

• how emigration is defined and tracked in Canada

• what long-run “Canadian diaspora” estimates look like

• what recent annual emigration counts show

• what indicators exist for highly skilled mobility to the United States

• how non-standard work (including platform work) appears in recent labour data, including among recent immigrants

This article reports findings from official statistical releases and research publications and focuses on definitions, counts, and measurable patterns.

Key definitions (for clear measurement)

What is an emigrant in Canadian population statistics?

In Canadian demographic accounting, an emigrant is generally counted as a Canadian citizen or immigrant who leaves Canada to live abroad on a permanent basis (as defined in Statistics Canada demographic methodology and glossary materials).

What is “brain drain”?

Brain drain is defined as the departure of educated or professional people from one country, economic sector, or field for another, usually for better pay or living conditions.

Important note on measurement:
“Brain drain” is not a single official statistic. It is usually assessed using proxies such as:

• emigration counts

• the characteristics of emigrants (education, occupation, earnings potential)

• destination-country administrative indicators (for example, U.S. processes tied to skilled employment)

1) Canada’s diaspora: how many Canadian-born people live abroad?

Statistics Canada has compiled and reconciled multiple approaches to estimating Canadians abroad, including UN-based counts and scenario methods. A headline result in that work is:

• Around 1.3 million people born in Canada were living abroad (2017 UN-based figure).

• The United States is the main destination for Canadian-born people living abroad.

• The destination mix has diversified over time, with the U.S. share lower than in 1990.

These estimates describe the stock (how many are abroad), not the annual flow (how many leave each year).

---

2) Recent emigration flows: what annual demographic estimates show

Statistics Canada’s annual demographic estimates track emigrants and returning emigrants. In the COVID-era year highlighted in the estimates:

• Emigrants were reported as 29,677 in 2020/2021, down from 36,899 in 2019/2020.

• Returning emigrants (people returning to re-establish residence in Canada after living abroad) were reported as 8,256 in 2020/2021, down from 54,524 in 2019/2020.

These figures are part of the demographic components used to describe population change and international migration dynamics.

Interpretation constraints: These counts describe total emigration, not specifically “high-skill” emigration.

3) A measurable proxy for “brain drain”: Canadians pursuing long-term skilled jobs in the U.S.

One of the clearest “high-skill mobility” indicators available in recent Canadian analysis is based on Canadian citizens applying for U.S. permanent labour certification, a procedural step tied to employer-sponsored permanent residency (Green Card pathway).

Key findings reported for 2015 vs 2024 include:

• Total Canadian-citizen applicants declined from 3,309 (2015) to 2,459 (2024).

• In 2024, foreign-born Canadian citizens accounted for 60% of Canadian applicants (up from 54% a decade earlier).

• Applicants were concentrated in high-skill fields. In both 2015 and 2024, about 46% were in:

  • computer and mathematical occupations, or

  • architecture and engineering occupations

• Median wage offer (constant 2024 U.S. dollars) was reported as $144,000 (2015) and $137,000 (2024).

• The share holding a master’s or doctoral degree declined from 41% to 31% over the period.

Table 3. Selected characteristics of Canadian citizens applying for U.S. labour certification

This dataset is often used as a “brain drain” proxy because it directly connects mobility to skilled employment pathways, occupations, and wage offers.

4) Labour-market context: gig work and digital platform work in Canada

Gig work (main job) measured in Q4 2022

A Statistics Canada framework report using Labour Force Survey supplements reported:

• In Q4 2022, 871,000 Canadians had a main job with characteristics consistent with gig work.

  • 624,000 were self-employed gig workers (as defined in the report’s measurement approach).

  • 247,000 were paid employees in a main job with gig-work characteristics.

• An additional 1.5 million people reported doing freelancing, paid gigs, or short-term tasks at some point during the prior 12 months (not necessarily as a main job).

Digital platform work measured in 2024 (12-month prevalence)

Statistics Canada’s Labour Force Survey (December 2024 release) reported:

• 665,000 Canadians (2.3% of the population aged 15 to 69) did paid work through a digital platform in the 12 months ending December 2024.

• This included 495,000 providing services through platforms. Common services included:

  • delivery of food or other goods

  • personal transport

  • creation of content (for example, videos or podcasts)

• The release also reported differences by population groups, including:

  • higher platform-work rates among some racialized groups compared with non-racialized, non-Indigenous Canadians

  • higher platform-work rates among immigrants admitted in the previous five years compared with Canadian-born persons

Table 4. Gig work vs digital platform work (what each measure captures)

Interpretation constraints: These labour measures do not directly measure emigration, but they provide context on non-standard work patterns that can intersect with income stability, occupational matching, and workforce transitions.

5) What the data can and cannot conclude about “brain drain” in Canada

What can be reported directly

• Canada has measurable emigration flows and measurable diaspora stocks.

• There are datasets that describe skilled mobility pathways to the U.S. (including occupations and wage offers).

• There are official measurements of gig work and platform work prevalence in Canada, including differences across demographic groups.

What requires additional data to confirm

To quantify “brain drain” precisely, additional linked evidence is typically needed, such as:

• education and occupation of emigrants in Canadian emigration counts

• longitudinal tracking of skilled immigrants leaving Canada after admission

• destination-country visa categories and labour market outcomes combined with Canadian characteristics

FAQ (AEO-friendly)

Is emigration from Canada measured officially?

Yes. Statistics Canada publishes demographic estimates that include emigrants and returning emigrants as components of population change.

Is “brain drain” an official Statistics Canada measure?

No. “Brain drain” is a concept typically measured using proxies (for example, skilled-worker flows, high-skill visa pathways, and characteristics of movers).

What is a concrete indicator of skilled moves from Canada to the U.S.?

One recent indicator is the number and characteristics of Canadian citizens applying for U.S. permanent labour certification, including their occupations and wage offers.

How big is the Canadian diaspora?

Statistics Canada has reported UN-based counts indicating around 1.3 million Canadian-born people living abroad (2017), with the U.S. as the main destination.

Is gig work the same as platform work?

Not necessarily. Gig work can be offline or online; platform work specifically involves digital platforms that coordinate or manage work activities and payment.
