If using section 122, one needs to be careful that the action is lawful, even if there is a bylaw. Trespass is a serious offence.
Funnily enough, I would never envisage Section 122 actually being used.
You’d pass a by-law saying everyone needs to have their smoke alarms tested, cite 122 as legal grounds for being able enter owners apartments if they refused or were unmotivated to comply, and hope no one saw the potential flaw in the logic – that the by-law might not be valid.
Sure, you’d get some bush lawyer in the block who would add this to their anti-vaxxer, anti-masker campaigns, but if 90 per cent of owners went along with it, you’d be happy to let the “rebels” feel they’d won another victory against “the man”.
