https://www.taxtips.ca/calculators/basic/basic-tax-calculato... is a good resource - it shows that your effective tax rate in Ontario on $150k gross is 30.3%.
You probably also contribute 18% to your RRSP on that huge salary, which drops your effective tax rate to about 27.4%.
Also, you aren't paying 13% VAT on everything you buy - lots is exempt like food and your mortgage/rent. Even if you spend every dollar of your net income, VAT is probably closer to 8% of your total net income (which is 72.6% of your gross, so 5.8% of your gross going to VAT).
CPP and EI total $3754 in 2020, so that's another 2.5% total.
So that's a total of 35.8% tax on your gross salary. Also note it's much less if you have any common deductions, like children, dependents, education expenses, etc.

I believe that there have been similar effects in ON from increases & new brackets, on both the federal and provincial level.

2015 top bracket: "over $151,050"
2019 top bracket: "over $205,842"
So anyone anywhere near that bracket, despite the increased percentages, is probably paying less tax overall.
Depends on where and depends how you're counting it.
In Ontario, Canada, and I'm not an accountant so very approximately based on GoC website:
At ~~$150k CAD you are at 29% federal + 12 % Provincial tax.
On anything you buy though you get another 13% VAT
So now we are at 54%, plus CPP and EI.
Plus any other taxes - property, land transfer, etc - overall it's well above 50% for what would be ~100k USD
