C-45 first was a big deal because Harper went ahead and ratified it without any sort of debate or discussion with his MPs. Some weren't even sure about it happening. The bill basically allowed foreign interests to deal, buy and sell and utilize canadian land if they bought it. The land that fell under this, incidentally, was also treaty land, where Canadian government law isn't really applicable and the people who lived there were fucking pissed, rightfully so, to have their land able to be bought, logged, and fucked up the ass by others and it didn't even get due process!

C-45 was dubiously legal because normally a bill like that gets a once-over by everyone through the government, yknow, adding stuff or discussing it and none of that happened. It just was proposed and then passed. Uh, okay then. Nobody had any say, because nobody fuckin' knew!

A few bills have been repealed by the trudeau govt recently, many to do with fucking around with unions and removing worker rights, and the ruling here has all but made c-45 kinda null and void and removed the greatest fears Canadians had: our land would be pillaged by whoever bought it. It'll remain as pristine and untouched as it is now, as it should be, because you can't "perform industry" on it anymore. This means no pipelines, no logging, no nothing.

If you weren't around for when this began, there were mass protests, people in chains, literally impeding surveyors. It was pretty intense. They won, and a victory for the people whose land it is is a victory for us. Now, C-45 hasn't been voided, yet, but it's all but useless over a large swath of Canada, now. Honestly I don't see any shit happening with it, anyway, because most people presiding over those areas are anti-industry-interference anyway.

tldr the bill isn't gone but it's all but useless now. It's only a matter of time, this is a great step and we can pretty much celebrate now.
