Construction Industry of Canada

The construction sector is worth US$126.3 billion and accounts for more than 7% of Canada’s GDP. In 2018, the industry employed over 1.4 million Canadians and purchased products and services from all regions of the country and segments of the economy, making it a barometer of overall economic health. There are four types of construction: new home building and renovation (single and multi-family), heavy industrial, commercial and institutional, and civil engineering.

The construction companies in Canada are widely regarded as a leading indication of the country’s overall economic health. Canada’s six largest urban centers, Toronto, Vancouver, Montréal, Calgary, Edmonton, and Ottawa, continue to have the greatest home starts, thanks in part to an influx of over 320,000 immigrants in 2018. In 2018, there were 212,843 home starts across Canada, with Ontario leading the way with 78,742 starts, followed by Quebec (46,874) and British Columbia (40,857).

Residential starts for 2019 fell by more than 13% in the first quarter due to restrictive government rules to temper hot housing markets, particularly in Vancouver and Toronto, such as greater down payment requirements, stricter loan-to-value ratios, and hikes in mortgage insurance premiums. According to industry experts, British Columbia is expected to lead Canada’s building boom over the next decade. Ontario also leads in Industrial, Commercial, and Institutional (ICI) building, with US$4.8 billion in 2017. Alberta, on the other hand, dominated civil engineering construction in 2017, with US$8.3 billion. Nonresidential developments are expected to grow by 18.6% in 2018.

Conclusion

The Canadian government is committed to building and maintaining infrastructure across the country. They have allocated more than $180 billion (CAD) in infrastructure over the next decade under the ‘Investing in Canada Plan.’ The proposal includes long-awaited financial initiatives for public transportation, affordable housing, and rural community development. Green energy is another potential investment sector.

The construction companies in Canada are intent on developing and driving innovation. Artificial intelligence, drones, 3D modeling, and successful project delivery models are helping to reduce waste, increase efficiency, and promote sustainability in the construction business. Automation poses a possible threat to several job sectors, including the construction industry. However, when compared to the manufacturing, retail, and agriculture industries, the construction sector is comparatively less vulnerable to technological employment losses. Much of the daily work in construction is difficult to replicate with machines, which shields it from the consequences of automation.
