Ongoing History Daily: How long should you listen to loud music?

All kinds of music require volume. It has to be listened to loud. But how loud and for how long? Here’s a quick guide.

  • If you listen to music for long periods of time, 85 dB is about the maximum. You can listen for up to eight hours with no damage to your hearing.
  • But turn things up to 88 dB, and the tolerance drops to around four hours.
  • At 91 dB, two hours, max. If you’re at 94 dB, you’d better stop after an hour. Beyond that, things can get dangerous.
  • If sound pressure levels are at 100 dB, you may suffer hearing damage in as little as 15 minutes.
  • And if things are at 110 dB or beyond, damage starts within a few minutes. If you’re near the speakers, problems start within seconds.

Ongoing History Daily: Facts about vinyl everyone should know (part 4)

If you have a stereo set-up at home, you’ll know that there’s a special input for your turntable labelled “phono.”  You can’t just plug it into, say, an auxiliary input. If you can use an aux input for everything else, why not your turntable?

Because in order to play back vinyl correctly, it has to go through something called a “phono stage.” Vinyl has limitations when it comes to storing very low frequencies and very high ones. To counteract that, records are pressed with the bass turned down and the treble turned up per something called the RIAA equalization curve. Upon playback, the phono stage reverses that curve, boosting the bass by a specific amount and reducing the treble, thereby achieving the tonal balance of the original recording.

The RIAA curve may help explain why it feels better to listen to vinyl than a digital recording.

Ongoing History Daily: Facts about vinyl everyone should know (part 3)

A vinyl record features a continuous groove that begins on the outer edge and spirals in toward the label. How long is that groove? It depends on how much music is on the side of a record, but a general length is somewhere around 500 metres.

How wide is that groove? Anywhere from 40 to 80 microns, which can also be expressed as 4 one-hundredths to 8 one-hundredths of a millimetre. That’s about the width of a human hair.

There are a couple of oddball exceptions to this. For example, in 1973, Monty Python released an album called Matching Tie and Handkerchief. One side of the record secretly had two spiral grooves side by side. Depending on when you dropped the needle, it caught one groove or the other, resulting in completely different audio. Imagine trying to figure out why that side of your record was different when you went to play it.

Ongoing History Daily: Facts about vinyl everyone should know (part 2)

Last time, I talked about how the weight of a vinyl doesn’t necessarily impact the quality of how it sounds. Okay, so what about rotational speed?

Some people swear that 45 RPM records sound better than those that rotate at 33 1/3. This is true if you’re talking about 12-inch records. Because the record spins faster, the stylus travels through more grooves per second. This means that the wiggles the stylus makes are more spread out, meaning that they’re easier to track.

Think of it in terms of the resolution of an audio file. Something that is encoded at 320 kilobytes per second will sound better than the same song located at 128. This explains why bands like Radiohead have released albums as two slabs of 45 RPM vinyl instead of just one that spins at 33 1/3.

More next time.

Five Songs You Must Hear This Week (06 July 2026)

This week’s Five Songs You Must Hear list features five indie acts from around the world that more people need to know about. Spread the word.

1. Winter Garden, Fragile Boy
Single (Independent)
Recommended If You Like: Fuzzy dream-pop

Some lovely stuff out of Brighton, England, that blends the dreaminess of the Cocteau Twins with the fuzziness of shoegaze that’s garnished with a little psych and a touch of Goth. They’ve already had support slots for Gary Numan, Echo and the Bunnymen, and Modern English.

2. Commuter, Guilt Beats Hate

Magnolia (Independent)
RIYL: Overcoming odds

Johnny used to be a singer for a variety of punk bands in Basel, Switzerland. He’s unable to play a physical instrument because of a disability (he’s confined to a wheelchair), but that hasn’t stopped him. He uses a laptop and a variety of MIDI instruments. As someone who flies long-haul a lot, I get this song.

4, Last Second Dropout, Aspartame
Single (Independent)
RIYL: Artificial sweeteners?

This is power pop from Brooklyn led by a guy named Mark MacDonald. He describes himself as the equivalent of Billy Corgan rapping some Eminem over a Green Day song. Production is by Canada’s GGGarth Richardson. The video is a riot.

Federal employees now working four days a week seeing less office space

Federal public servants will be expected to spend more time in the office. Unions are pushing back against this latest order, one that comes as Ottawa looks to cut thousands of jobs. And those public servants who rallied behind Prime Minister Mark Carney during the election might be second-guessing their decision. As Jillian Piper reports, for many, it feels like a betrayal.

Thousands of federal public servants are starting a new work schedule Monday that will see them on-site in the office four days a week, though a lack of office space is delaying the return for some departments.

The Treasury Board announced the change to remote work rules in February. Executive public servants returned to the office full-time in May.

Jeffrey MacDonald, a spokesperson for Immigration, Refugees and Citizenship Canada, said most of the department’s employees will work on-site only three days a week until the department secures enough office space. Managers will have to work on-site four days a week.

Health Canada and Public Health Agency of Canada spokesperson Mark Johnson said while most of their offices have enough space, some areas may have “localized space challenges.”

“In a small number of regional offices, implementation will be staggered beginning July 6, 2026, due to local space limitations,” said Johnson.

Natalie Huneault, a spokesperson for Employment and Social Development Canada, said the department is implementing the new rules but some locations still need more space to accommodate employees.

Jason Kung, a spokesperson for Global Affairs Canada, said the department is undertaking a multi-year renovation project that’s affecting the availability of office spaces. The project includes renovations of its headquarters and other buildings in the Ottawa area.

Until there is enough workspace available, Kung said, all managers and deputy directors will be required to work on-site four days per week, which will be phased in between July 6 and September 15. He said all other employees in the National Capital Region, as well as some employees in regional offices, will continue to be required to work on-site three days per week.

“As renovation projects advance and additional renovated space becomes available, on-site presence will increase in line with (Treasury Board of Canada Secretariat) direction, ensuring employees have the space needed to carry out their work effectively,” said Kung.

Most public servants were told to work remotely when the COVID-19 pandemic hit in March 2020. Core federal employees have been working three days in-office since September 2024, after the standard increased from two days.

Federal unions have fought the government’s back-to-office directives and some have filed unfair labour practice complaints.

Nathan Prier, president of the Canadian Association of Professional Employees, is set to deliver remarks at a demonstration in front of the Prime Minister’s Office on Monday morning to denounce the new rules.

The union argues the return-to-office order is a “handout” to four banks — CIBC, National Bank, BMO and RBC — to protect their roughly $10 billion worth of commercial real estate office exposure.

“Carney needs to explain, clearly and with evidence, why his government is forcing workers back into offices when the public rationale and $40 billion of costs, plus likely hundreds of millions in commercial real estate costs and maintenance, do not add up at a time of deep cuts to programs and services,” the union said in a news release Thursday.

Sean O’Reilly, president of the Professional Institute of the Public Service of Canada, said in a post on the union’s website last week that members are frustrated, disappointed and angry about the new rules.

“From the beginning, we opposed a one-size-fits-all return-to-office mandate and advocated for a presence-with-purpose approach based on operational need,” said O’Reilly, who added that the union has filed policy grievances, launched an unfair labour practice complaint and escalated matters to the Federal Public Sector Labour Relations and Employment Board.

“PIPSC will continue challenging this policy through legal, bargaining, public and political channels.”

Some members of Parliament have also pushed back against the updated policy.

MP Bruce Fanjoy represents the Ontario riding of Carleton, which is home to more than 10,000 public servants. Since the new policy was announced earlier this year, Fanjoy has pushed for a “flexible” hybrid model with a mix of in-office and remote work.

“I think that we can do better than a one-size-fits-all return to office policy,” he told The Canadian Press on Friday. “You want to make sure that government services are provided effectively and efficiently, and there’s no reason to make life more difficult for people who are providing those services.”

Fanjoy acknowledged several departments are short of office space and said that shows that the policy is “practically difficult to accommodate.”

The MP said he hasn’t seen evidence the policy will boost productivity and argues hybrid work can cut costs for the government and reduce traffic and pollution.

“I just think that the benefits of flexibility far outweigh any other alternative,” he said. “I’m not afraid to let people know where I stand on this issue.”

Ongoing History Daily: Facts about vinyl everyone should know (part 1)

If you’re into vinyl, let me give you some extra knowledge. First of all, you’ve probably heard about 180-gram records, which tells you the amount of vinyl used in a record. The heavier the record, the better, right? Not necessarily.

While they resist warping better than standard 120- and 140-gram records and may allow for better tracking of the stylus within the grooves, sonic quality still comes down to the nature of the recording, the mastering process, and the care with which it was pressed. The weight of the record doesn’t automatically mean it sounds better. A 140-gram record made with more care will always sound better than one that weighs 180 grams but was sloppily made.

So what is the best weight for a vinyl record? There is no consensus and no impact on sound quality. More next time.

Trump administration not meeting or strategizing with Alberta separatists: Hoekstra

This story is the second of two installments of a feature interview with U.S. Ambassador to Canada Pete Hoekstra. Read also: U.S. ambassador denies donations delayed Gordie Howe Bridge opening

U.S. Ambassador to Canada Pete Hoekstra says the Trump administration has not met with Alberta separatists, nor discussed any potential financial support for an independent Alberta, directly contradicting claims made by prominent separatists.

No, we’re not meeting with the separatists and strategizing this at all,” Hoekstra told Global News.

A report in the Financial Times, citing sources familiar with the talks, said leaders of the Alberta Prosperity Project met three times with U.S. State Department officials in Washington since April.

Alberta Prosperity Project leader Jeffery Rath, the group spearheading the separatist movement, has publicly stated his organization has met with American officials. That includes a meeting with US Treasury officials to discuss a potential US$500-billion line of credit for an independent Alberta.

Hoekstra was dismissive of the separatists’ claims, saying “separatists can say whatever they want.”

Asked if there were conversations about a potential line of credit with the separatists, Hoekstra said “no, not that I know of.”

When asked if the Trump administration wants Alberta to stay a part of Canada, Hoekstra would not give a definitive answer.

“That’s the president’s call,” he said. “I think at this point in time, we’ve made it very clear we are not going to take a position on that. That’s a decision that has to be made by the people of Alberta, the province of Alberta, and the federal government.”

That position offers a stark difference from a previous administration.

During the Quebec referendum campaign in February 1995, then-U.S. President Bill Clinton called for a united Canada.

“Canada has stood for all of us as a model of how people of different cultures can live and work together in peace, prosperity and respect,” Clinton said in a speech to the House of Commons.

Hoekstra anticipates the Trump administration will not get involved in the fall referendum.

I’m not going to get a directive, I don’t believe, from the President of the United States, from our Secretary of State, Marco Rubio, that says, ‘Pete, go out there and do what you can to advocate for, secession or for the people of Alberta to vote to stay as part of the Confederation,’” Hoekstra told Global News.

Despite the ambassador’s claim of not getting involved in Alberta politics, several premiers criticized Treasury Secretary Scott Bessent after he said in January that Alberta is a “natural partner for the U.S.

“The Albertans are a very independent people,” Bessent said on the Real America’s Voice podcast. “They want what the U.S. has got.”

Hoekstra dismissed Bessent’s comments, saying, “Canadians get upset about a number of things.

“There are lots of instances of Canadian politicians saying things about American politics or American policies and those types of things that I’m not happy about,” he said. “I don’t focus on them.”

General Motors says renewal of CUSMA 'very important' for auto industry

WATCH: What comes next for Canada after the July CUSMA review

As uncertainty remains around North American trade relations, one automotive player is saying the Canada-United States-Mexico Agreement (CUSMA) is “very important” to keep the industry well-integrated.

Speaking to Global News at the Calgary Stampede on Sunday, Jack Uppal, president and managing director of General Motors Canada said CUSMA protects the North American industry against other global players and “makes it stronger.”

Last week U.S. President Donald Trump said his country would not be renewing the agreement in its entirety to 2042 (the termination date of the pact’s potential 16-year extension) and instead would require an annual review.  If no extension is agreed upon, the agreement will expire in 2036.

Last month Trump suggested that the U.S. is “better without” CUSMA, and that he’d even prefer to see it “terminated.” When asked by Global News, U.S. Ambassador to Canada Pete Hoekstra would not say if the administration is considering ripping up the deal, which can be done by any party with six months’ formal notice.

“All options are on the table,” Hoekstra said. “ clearly is allowed for within the agreement.”

CUSMA has largely shielded Canada and Mexico from the effects of tariffs imposed by the Trump administration. Uppal said tariffs is something GM has been monitoring closely, but so far the company has been able to protect its go-to market price points.

“What we need to focus on really is ensuring that we keep our customer in the lens and we manage the affordability piece,” he said.

GM finished the first half of 2026 as Canada’s best-selling automaker, with 15.4 per cent market share and 148,640 vehicles delivered. That includes more than 30 per cent in growth of electric vehicle (EV) sales year-over-year. Even in Alberta, which has some of the lowest uptake of EVs, GM EV sales increased around 30 per cent.

“We are in an environment that is quite uncertain from a geopolitical perspective; we’ve got tariff noise, but at the heart of it is affordability,” Uppal said. “So that’s where I would really respond to those challenges. We have to double down and really focus on ensuring that we’re delivering value across our product portfolio to our customers to dampen the noise that nobody can really change.”

Despite shifting significant production to the U.S., Uppal said many of GM’s values still align with Canadian consumers.

“We are seeing the consumer really demanding more choice, more tech, more connectivity,” he said. “Choice is absolutely critical.”

Uppal said he does believe the uncertainty surrounding the trade agreement will “sort itself out” as talks continue among the three countries. But Canadian government officials are less certain.

Canada-U.S. Trade Minister Dominic LeBlanc told The Canadian Press he asked U.S. Trade Representative Jamieson Greer how he intended to structure discussions as part of the annual review. He said the request was made jointly with Mexican Economy Secretary Marcelo Ebrard.

“There wasn’t an answer at the meeting … It was agreed that we would continue the conversation over the coming weeks,” LeBlanc said.

The renewable annual review process, set in motion by the Trump administration, could last up to 10 years. At the end of that period, the agreement would expire if no path forward is found to extend it beyond its 2036 expiry date.

Exactly how those annual reviews will be conducted has yet to be determined.
