They certainly could use Section 33 to over-rule a court decision that used Section 7 (the "right to life, liberty and security of the person"). But the 1982 Charter didn't override any pre-existing rights. So I don't see how they'd get past the "the right of the individual to life, liberty, security of the person and enjoyment of property, and the right not to be deprived thereof except by due process of law" without rolling it back, doing appropriate consultation.
Though if one went down this route, you don't need to win at the Supreme Court - several years from now. You merely need to punt this until far enough in the future that it's a non-issue.
At the same time though, the amount of international ridicule Ford would get by suspending Human Rights and Fundamental Freedoms for ... replacing bike lanes with car lanes would be epically hilarious!
