The latest meme stock mania is being driven by a historic short-squeeze that raises the risk of a downturn, Goldman warns - Yahoo! Finance Canada

TORONTO — In the absence of surefire technology to determine whether something was written by artificial intelligence, some Canadian publishers say they have to rely on something nearly as thorny: trust. Alana Wilcox, the editorial director of Coach House Books, wrote in an email that the company asks writers to be upfront about whether their work contains material generated by AI. She says the existing tools to discern the use of AI aren’t reliable. There is renewed attention on the role of artificial intelligence in the book industry after a Quebec publisher cut ties with an author accused of using AI to write his debut novel. Earlier this week, Montreal-based publishing house Les Éditions du Boréal said an analysis of some documents’ metadata found evidence author Thélyson Orélien used AI while writing his novel “C’était ça ou mourir” (“It was either that or dying”). Allegations that Orélien used AI in his book first emerged on social media in September. The author denied using AI to write the book but said he had used it for research. Orélien did not respond to The Canadian Press’ request for comment following the publisher’s announcement on Wednesday.

The cost of building out the infrastructure needed to satisfy booming demand for artificial intelligence is changing the way major companies allocate resources. That can mean an end to some jobs once done by humans. Yet in many cases it means repurposing money once spent on workers so that more capital can be devoted to boosting AI capabilities. Just how much money is being spent on AI is a hot topic as fears of a bubble in the sector grow, but the potential impact on workers in some sectors is clear. Here’s a look at some of the companies that have announced layoffs or hiring reductions this year that are tied in some way to massive spending on AI. BarclaysThe U. K. bank and financial services company revealed in a quarterly financial report this week that it is looking to cut 5,000 jobs, or about five per cent of its workforce.

Published: October 23, 2026 at 2:26p.m. EDTScott Unger, co-founder and CEO of Kahua, joins BNN Bloomberg to discuss the barriers for construction companies to deploy AI. AI use is widespread in construction, but significant returns remain elusive. A Kahua survey found that only eight per cent of respondents reported significant value from their AI investments. BNN Bloomberg spoke with Scott Unger, CEO of Kahua, to discuss the survey’s findings and what they reveal about the construction industry’s adoption of artificial intelligence. How to set BNN Bloomberg as your preferred source on GoogleKey TakeawaysAI embedded directly into construction applications can deliver greater value than tools used separately from core business processes. Human review remains essential to check AI-generated information before accepting it as fact. Complex construction projects generate vast amounts of data that AI can help manage throughout design, construction and ongoing operations. Consolidating systems can reduce data silos created by numerous applications and project stakeholders.

Recent share price weakness has put several consumer businesses under scrutiny. Auto repair, specialty food and bottled water offer opportunities for those looking beyond the recent declines. BNN Bloomberg spoke with Derek Lessard, analyst at TD Cowen, about his picks of Boyd Group Services, Premium Brands and Primo Brands, and why he believes their shares have room to recover.

Premium Brands’ completed capital spending program could support stronger free cash flow, while a potential distribution business sale could help reduce debt. Limited-time offers have added sales volatility at Premium Brands, but Lessard says underlying demand remains strong. Lessard believes Primo Brands’ merger integration challenges are behind it, with retail market share gains supporting its recovery prospects.
