This is again a place where the CRA would have to ultimately interpret the language, but one possible implication is that the language under the existing deduction is explicitly intended to say that you moved closer to the work site. You found temporary lodging that was closer to the work site than your home was. In Bill C-241, if the work site is at least 120 km away from where you live, travel to and from the work site is deductible.
It's unclear to me whether this means that, if you have lodging near the work site, you can deduct your commuting expenses back and forth from your temporary lodging to that work site. That might be 15 kilometres, because that work site is 120 km away from your home. I don't know if that's the intention or not, but that would be one possible difference. The existing deduction is only for travel between your home and the work site.
