Here is the problem that the SCC judges, with little actual trial experience, did not anticipate: defence counsel no longer have any incentive to expedite trials by agreeing to admissions and focusing trials on live issues. 
We are entering an era of long trials - with courts tied up in knots listening to the Crown call a parade of witnesses to prove routine aspects of their cases. I hope that Legal aid will increase oversight to ensure that counsel are not litigating every issue under the sun just to run the clock.
