https://calisphere.org/item/c808aa829349df0b62b97853207d216fhttps://en.wikipedia.org/wiki/611_Place Its a 42-story, 189 m (620 ft) skyscraper at 611 West 6th Street in Downtown Los Angeles. It was completed in 1969, some 7 years after PVM in Montreal. 611 Place is a few feet higher or a meter taller, but PVM is much wider building. It would take until the early 21st century before strict Vancouver would permit a building to rival their height.
PVM:

Some of the floors and of course the roof, have no windows, as they are mechanical or building plant operation levels.
Although it's not quite the tallest in Montreal, PVM is the tallest wide building in Quebec. It really should have been in the 55-60 story range, but Montreal wasn't ready for a big, bulky NYC office tower on the scale of 28_Liberty_Street or the MetLife_Building. Montreal has some view corridor restrictions, which prevent it to rival the tallest buildings in Austin Texas. However, Montreal is still allowed to have taller buildings than stumpy Vancouver.

wide streets or
boulevards. Wide streets can allow for better accomodation of bus & bike lanes. The Vancouver approach is to try to cram everything into 4 lanes.
"This widening to 8 lanes was requested by the real estate developer planning the construction of Place Ville-Marie . This urban gesture allowed the arrival of several tall buildings, especially in the city center. It is without a doubt the boulevard of skyscrapers since it is on this artery that the largest buildings in Montreal and Quebec are located."
