Those who cannot be rehabilitated and don't deserve to live a normal life should be kept in jail (and I am more than okay with paying taxes for them to do so) and those who can should get proper rehabilitation services for them to become contributing members of society. At this point we really have neither, and thus brings us to the ridiculous amount of crime we have.
Most inmates in Headingley are there for crimes of stupidity or they are victims of drug prohibition. Criminal masterminds are pretty thin on the ground. Lots of gang members having stupid contests, riots being the acme of that art. You live under the law of the jungle, the toughest guy is always right. Whoever has the highest level of violence on tap runs the place, with the tacit consent of the staff. Bullies give workshops in their art at the slightest provocation. The guards generally get there too late or not at all.
Think jail is a great place to be? Then you're merely flaunting your ignorance. I feel sorry for anyone who's life is so pitiful that they would think jail was an improvement. All those great facilities? First off, they're not so great. Second, you have to be ready to fight for these privileges. Since you're going to be seeing these people at close quarters for a while, not a good strategy. It's generally best to leave that sort of thing to the gangs and just keep your head down and read a book.
Some people belong in jail but most don't. Maybe the commenters that are designing schemes to have their revenge on anyone that runs afoul of the law could instead bend their wit to coming up with a way to deal with these non-criminals. Something like a halfway house might be the answer. Helping is a lot better for the soul than hating.
This is a tough situation for Mr. Toews. I do think that parole should be earned, but for the ones that don't earn it, this will only make it more likely that they reoffend when they get out. There should still be certain conditions for those that are released after serving a full sentence. Hopefully Mr Toews addresses this issue as well.
generally we don't send people to jail for non-violent crimes. Except for maybe drug crimes, which I don't quite agree with. Most of the time people in jail have committed some sort of violent crime, and then jail is justified. However like I said, there should be better rehabilitation services. I'll admit a big problem is gang members getting together and plotting things out in jail, and I'm not sure what the best solution would be to that, but I think it would help to have options for them. You can't force treatment or rehabilitation on them, so if the options are there and they still choose to lead the gang life, even in jail, then that's their call. They can continue down that life and so long as they are kept in jail, then it's not really a worry of society's.
Jail is probably the biggest obstacle to rehabilitating the criminals that could be rehabilitated. All it teaches is things like might is right. Weapons help. Violence pays. I have no problem with locking up violent people but jail has nothing but a negative effect on non-violent people. We shouldn't be throwing them in for the bullies and misanthropes to feed on.
