Sad. I presume it is still legal to bike on those streets, or in the city, and so there's no actual traffic improvement during busy periods. Just less safe.
I'm not sure. I would bike on those streets before bike lanes, and the lanes have "taught" people how to ride bikes. For Bloor, There are side street routes east of high park/Dundas. College is ok. Short spurts on Dundas and Bloor (though this is high speed parts of those streets). After Humber river, west, there's more side street routes. Hopefully at least a painted lane still exists on those stretches, but it is not a parking area.

For now, it's still legal. But since you can't sue the government if/when you get hurt (or killed), and they've already said that "for your safety" to not ride a bike on those streets when the bike lanes are gone, you have a no-win situation.
Plus, people in cars are now emboldened to abuse cyclists, since the boss said it was ok.
