Please just face the reality, the bill is already dead. It's both parties interests to keep as it.
First, Conservatives definitely would not turn back their position two years ago and let it pass. But they also cannot reject the bill as it will jeopardize their reputation. So the best way is to hold it until the end of parliament session and let it naturally die.
Second, the bill is proved to be mistake and embarrassment for Liberals, they really don't have the will to push it. So letting it die naturally until the end of parliament session is also the best way for them. In the end they can say they already fulfill their election promise and try their best but blame Senate who hold it. In the past year, we all saw how hypocritical the Liberals are. Like many things they have done, C-6 is just one of shows they are running.
I don't like many policies Conservatives made in the past, but at least they are not that hypocritical, they put action where mouth is. They don't focus much on shows rather than actually doing something.
