It's happening, the worst mayor Toronto has ever had is removing three major recently completed bike lanes at tax payer expense. That's right, Ontario tax payers are footing the bill for Ford to meddle in Toronto municipal infrastructure. This is of course to distract us from failing healthcare and education while appealing to his mostly car centric base.
There is a protest happening Wed. 23rd of October, please come out if you can. https://www.eventbrite.ca/e/rally-ride-for-road-safety-tickets-1045417761667
I haven't lived in Toronto in years, but was a bike courier there in my student days. My recollections, dated as they may be, are as follows:
Bloor/Danforth is one of the best ways to travel east-west on a bike. The bike lanes have concrete dividers from car traffic along a lot of the length. There are other good options, but they tend not to go as far or be as well connected.
I saw the Danforth side last time I was visiting relatives in the area and was definitely impressed! I would hate to see them take away the cycle tracks there.
