The weird thing about surveillance is it's targets. If you want an orderly society and to enforce the law, there are easy ways to do so w/ no additional resources or powers. You can just start by enforcing the law. Open air illegal drug use, retail theft and illegal encampments are issues that plague many big cities. Addressing them would greatly improve the lives of nearly everyone, but for whatever reason there is just no political will. You can even just start keeping these repeat criminals in prisons longer.
I imagine these surveillance powers won't be used to address any of these issues, like cracking the network of retail theft. Rather they'll be used to arrest people for mean tweets. Canada is not as bad as UK at the moment, but consider the scope of what's tolerable these days in a Western society. For instance UK police reportedly made ~12,000 arrests, or about 30 per day, in one year over online communications offenses.
