The NTv2 GSB[1] for Canada is shared under the "Open Government License - Canada"[2].
I made a request some years ago and they did it! So it's definitely a good step forward. I'm not a license guru so not sure if it can be packaged and redistributed with FOSS (ie, QGIS or proj). I know for provincial (cause I'm in British Columbia) the Provincial Government has their own GSB for distribution, albeit a different and non-open license (I've asked for it to be switched to open license as well). I tend to use those, so asking with Provincial agencies/ministries would be a good bet too.
