When will formal trade talks between Ottawa and Washington resume? Take our business and investing news quiz for the week ending Sept. 11

d. Bombardier shares fell sharply on the Toronto Stock Exchange after Mr. Trump suggested he would ban Bombardier jet sales in the United States. Analysts say it’s not clear what legal mechanism the White House could use to stop the Quebec-based company from exporting into the U.S., but that’s not really the point of Mr. Trump’s tirade, is it? Things are getting nastier.

c. Restrain your hopes for a quick fix. Ms. Hillman, who served as ambassador and acting ambassador to the U.S. for more than six years, said she doesn’t believe Canada and the United States will resume formal negotiations any time soon. “It may be months,” she said, before U.S. negotiators realize Canada isn’t budging on key issues such as steel and auto tariffs.

Remember when Republicans prided themselves on being the party of fiscal responsibility? Not anymore. Based on 270 million adult Americans, Mr. Trump’s pledge would cost about US$1.35-trillion and swell the country’s already massive deficit by more than half.

b. For decades the United States was able to borrow money more cheaply than Canada was. But that has now shifted, rather decisively, as the rapidly worsening fiscal situation in Washington creates concerns about the country’s long-term outlook. The U.S. is now paying around 4.9 per cent on its 10-year bonds, a full percentage point more than Canada. Despite the trade war and budget pressures, international investors still see a lot to like in Canada.

d. Officials organizing the Canada Investment Summit have circulated a “prospectus” booklet to attendees outlining more than 160 projects that are open for investment, including a proposed $10.9-billion high-speed rail link between Edmonton and Calgary and a planned $57-billion Port of Churchill expansion project.

a. RBC will invest in Canadian technology companies that the lender believes could grow into “global powerhouses.”

b. Mr. Ternus made his public debut this week when he introduced Apple’s new product line-up. The long-time Apple executive took over the top job earlier this month. He is only the third person to hold the CEO post since 1997, when Steve Jobs returned.

a. Ms. Harradence, Enbridge’s executive vice-president and president of gas distribution and storage, will take over the top job when Greg Ebel steps down as chief of the Calgary-based energy transporter at the end of this year.

c. Bank of Montreal is eliminating commission fees on stocks, exchange-traded funds and options on its direct investing platform. It is hoping the fee cuts will attract younger customers as competition mounts in online trading.

a. Apple Iaunched the Duo, a folding iPhone that it hopes will shake up a category long dominated by Samsung and Chinese companies such as Huawei. Maybe so, but the price for the new iPhone is staggering – $2,999 in Canada. Ouch.

b. Jacob Coxon, who said he spent three years doing research at both Anthropic and OpenAI, says the two AI companies are more focused on beating each other than they are on safety. He warned that some working on AI development believe it could threaten human life by the end of the decade.

d. Mr. Wong will see an increase of 1.4 million Singapore dollars (about $1.5-million Canadian) in his annual pay package as the result of a decision by the Singaporean government to raise the salaries of senior government ministers so that the public sector can better compete for talent with private industry. Mr. Wong already earns 2.2 million Singapore dollars a year ($2.4-million Canadian), a level of official compensation well above that of other global leaders. Canadian Prime Minister Mark Carney, for instance, earns a mere $435,400 Canadian.
