Summary

The housing industry in British Columbia and across Canada is under pressure to deliver more homes, at lower cost, with fewer people available to do the work. Affordability constraints, climate and energy targets, and expectations for healthier, more durable housing are converging with a shrinking and aging construction workforce. At this same moment, the industry continues to rely on business-as-usual, informal, trickle-down approaches to training, assuming that knowledge held by licensed builders will reliably reach crews and subcontractors through on-the-job communication.

This paper argues that this assumption has created a widening gap between policy intent, training structures, and on-site practice, and that this gap is now leading to a critical systems failure.

Drawing on more than thirty years of lived experience in training delivery, curriculum development, and observation of housing outcomes, the paper uses a systems lens to show how information degrades as it moves from policy and building code, through formal education and licensing structures, to the people actually doing the work.

The “telephone game” is used as an analogy to describe how intent, context, and risk awareness are lost across a fragmented and subcontracted industry.

This gap becomes especially acute in the current workforce pinch point. Formal trades training programs face limited seats and instructor capacity, while many home construction and renovations firms operate without Red Seal carpenters and rely heavily on subcontracted labour. Trickle-down learning is understandable in a mentorship-based trade culture, but it is no longer sufficient given the complexity of modern housing assemblies and the safety, health, and durability risks involved.

This paper also considers who current training models reach, and who they do not. Women and other underrepresented groups remain a small share of the home construction and renovation workforce, in part because industry structures, learning pathways, and site cultures were not designed with inclusive entry or long-term participation in mind. Expanding workforce capacity and resilience will require training approaches that are accessible, relevant, and supportive, without assuming prior exposure or access to informal networks.

Recognizing the difficulty of changing the culture of an atomized industry, this paper does not propose a single fix. Instead, it identifies system-level options and enabling conditions for training ecosystems that better support consistent learning outcomes, distribute knowledge to the point of action, and treat direct-entry workforce learning as essential infrastructure for delivering cost-effective, safe, high-performance housing at scale.
