A nice succinct analysis (by an actual lawyer (law prof) who specializes in Canadian Internet law) can be found at

I think the court allowed them to. <quote> Telus Corp. is moving aggressively in the opening days of the showdown with its chief union, securing a sweeping injunction to limit picketing and blocking access to two pro-union websites. <snip> On the same day it obtained the injunction, Telus blocked its subscribers from a pro-union website, Voices for Change. The site is run by a union shop steward, but not funded by the TWU. The site is the host to discussion forums, in which some union members posted internal company documents that detailed safe methods for crossing picket lines, as well as digital photos of workers and managers still on the job. <snip> Bruce Okabe, Telus vice-president of business solutions, said his company would be "morally negligent" if it had not tried to cut off access, but would not say if his company would have blocked the site if another company had been the target. Mr. Okabe questioned why anyone would want to publicly distribute pictures of workers who had crossed picket lines, saying that to do so imperils the safety of those employees. </quote>
