"We are not in the same land mass as a city who did some good urban planning, therefore we can't do any similarly good planning."
While I laud your ambition; that's not what he said. You really are very assertive. May I suggest you consider you're among the most progressive Torontonians on this subject, treating your fellow posters as the enemy is not the right move.
It's not hard. Build a line and up-zone the land. The only issue is money and politics.
It's a whole lot harder than that.

Now can we insert some context back into this......
Pre-pandemic, Toronto's modal share for the private automobile (City proper) was a mere 46% Only one major City in the U.S. or Canada does better (NYC)
Moreover, Toronto's numbers are better than any major city in Australia, better than Dublin, Ireland and only slightly worse than Madrid, Spain (40%)
Yes, we need to improve, indeed, significantly so. But worth saying here, we have the largest investment in public transit history in Ontario now underway, with The Ontario Line, and GO Expansion, and Eglinton West and Yonge North and
the SSE.
Just stop and take a breath, and look at that, it's 40 new rapid transit stations, on top of GO Expansion, on top of the Hurontario and Hamilton LRTs; and the soon to be open Eglinton Crosstown and open late next year Finch West.

And more is coming, plus Bikeshare expansion, a doubling or more of the Cycle Track system............
I believe modal share in the City proper, for cars will drop to the same level as Madrid, or better within 10 years.
Meanwhile the suburbs remain more of a challenge.......with the modal share there still much higher for cars; but I do expect material progress on that over the next decade.
