I never said I approved of the senate stalling Harper's legislation. Harper is accusing the Liberal senate of holding up his crime bill, for example, but this is a large bill with constitutional implications so I can't tell whether Harper's claim is valid or just more political bellyaching. The Liberals offered to fast track this bill in the last session but Harper didn't co-operate enough to get it done. Now this bill is before a senate committee who is going through it line by line. The fact that Harper is getting impatient should be no surprise to anyone. He was born impatient.
This is a description of the senate's responsibility with respect to legislation that has been passed by the HOC. You seem to think the senate's role is to just rubber stamp what the HOC passes but there is more to it than that:

Chamber of Sober Second Thought
The Senate, in concert with the House of Commons, plays an important role in the operation of Canada’s government. In theory, any piece of government legislation must be approved by both the House of Commons and the Senate (as well as the Canadian Monarch) for it to become official law. This, however, raises the question: why does Canada have two legislative bodies to review and approve government legislation?
The ideal of democracy was cautiously accepted in the 1860s when the Canadian colonies negotiated Confederation. The primary worry was that the democratic participation of "regular citizens" in government would be detrimental to good government and policy making. As such, the Fathers of Confederation decided to provide an appointed body, the Senate, which would exercise “sober second thought” in the legislative process. The Senate was to comprise economic and social elites that would act as a check on the interests and policies of the “commoners” or “lower classes,” who were believed to dominate the democratically elected House of Commons. It is important to note, however, that this idea of an “elitist check” on the House no longer carries weight in contemporary Canadian politics. That said, the Senate continues to act as second legislative review on government legislation and action.
Routine Revising Chamber
Another role of the Senate, not explicitly provided for in the Constitution, is to act as a non-ideological, routine revising chamber that picks up flaws in legislation that have avoided notice during a bill’s passage through the House of Commons. Accordingly, the Senate might highlight confusing ideas or language in legislation, or raise questions about potential loopholes that may reduce the effectiveness of a particular law.
