Do very recent Canadian self-adhesives soak? I have not had any newer Canadian kiloware to soak in a while, but just acquired a small batch including P stamps to 2018/2019. I do not remember having issues with the ones from a few years ago.
All the Canadian P stamps can be easily removed with soaking.Some take longer than others but ultimately they will all give up the paper.I have never had to use anything but water.
