The article you posted is from 2009. That no longer occurs. Also, it was a "fine" from a private resort. It was not legally enforceable, as the resort themselves stated. It was basically just a request that they make a donation to NSR. The resort is, of course, within their rights to ban them.
However, none of this changes the fact that in practise SAR is completely free in Canada no matter where you are. I'm aware that SAR in the US is slightly less black and white, but none of that applies to Canada. This is coming from someone who skis 100 days a year in both the resort and backcountry in British Columbia. NSR is deployed multiple times per week year round, and 0% of those rescues are paid for by the people being rescued. Resort staff may help out once in while if the rescue is close to the resort, but the resort is never compensated for it.

No resort in Canada has ever, and would never follow though, because the resort doesn't want you to hesitate to call for help. A dead person is the worst case scenario for them. They can, and do, ban people for entering closed terrain though.
And in the case where you didn't enter the BC from the resort, you would have no agreement with the resort to begin with.
It certainly puts their efforts into perspective, including how easily people can run into trouble unprepared.
It's really the same as the US (other than our states and cities acting more like corporations), it comes down to who gets dispatched: if it's the government you're fine, but oftentimes if you're near a resort, it comes down to whether dispatch thinks the resort staff, a government agency, or a volunteer group is better suited for the rescue. If it's the resort, you might've agreed to give them the legal right to claw back costs.
