I don't think that Canada will fall apart if those two bills are not approved. 
The first is a sop to political correctness rather than an attempt to improve the wording. Yes, an amendment to the national anthem requires parliamentary approval. But is that the only wording change that makes sense? How many times must we repeat 'we stand on guard for thee'? Should there be an official reference to God (a Christian term) in a secular and multicultural country?
The second uses a legislative bullhorn to tell judges how to become more sympathetic. Are judges incapable of determining how to improve their behaviour and listening to public opinion?
Let's get real. If those two examples are used to condemn the Senate (without looking at good bills that have passed scrutiny) then perhaps the Senate is doing a good job.
