I am with Kirk that a reform of C-36 is probably not going to be high on Trudeau's list of priorities - especially after having been portrayed in the last leg of the campaign by the Conservatives as being ready to let brothels open pretty much anywhere.
Already the Liberals had taken a very cautious approach in terms of where they stand on the issue: they voted against C-36 because they didn't believe it followed the spirit of the Bedford decision, but they certainly haven't said that they were in favour of decriminalization or legalization.
They were supposed to discuss a proposition to legalize prostitution at their convention in 2014, but this was removed at the last minute as Trudeau had expressed that he felt "prostitution is a form of violence against women."
Even if a court challenge is successful, I believe where changes might be happening would be the sections regarding advertising, etc., which directly impede the ability of the ladies to work safely.
The sections which criminalize the purchase of sexual services would need to be demonstrated to be just as detrimental to the ladies' safety in order to be found unconstitutional. The body of evidence to demonstrate this before the Courts is lacking at the moment. There is a fair amount of evidence in other countries, Sweden for instance, but not so much in Canada. I believe there is research being done on the subject currently, but it's going to take a while before any of this gets disseminated.
In the meantime, and even though LE by and large has only focused its attention so far on the most problematic issues (street sex work, underage, trafficking, pimping), I agree with Kirk's suggestion that clients should "hobby" judiciously and discretely.
