I also can’t say whether the site was studied sufficiently, but the timelines talked about in the article combined with bill C-15 allowing ministers to except entities from environmental laws if they are pursuing something to be deemed as encouraging economic growth pushes me well beyond the point where I’m willing to give the government the benefit of the doubt.

Fair enough - the article you linked described the study of Yucca Mountain as a storage for nuclear waste as having taken about 20 years, whereas as near as I can tell, they started exploratory drilling in Cold Lake in 2022. That's...less than 20 years, no doubt about it.

nearly all CCS projects in the U.S. are actually enhanced-recovery projects that keep the oil and gas flowing

This is undoubtedly the case for his project, as well. Even the most optimistic viewpoint seems to be that it would make the effects of continued drilling and export of oil "less bad," and do nothing to actually stop climate change.
