Background / Public Service Announcement: This year, the CRA has started requiring taxpayers to file returns for joint accounts (I think joint accounts for spouses are not included). These are called "bare trusts" and one needs to - register with the CRA to get a trust number (kind of like a SIN) - file a T3 tax return (but there will be no tax) - file a T3 Schedule 15 form for each beneficial owner.

Today I learned that Adobe Reader again supports Linux. I'm pretty sure it will be horrible: large, not really native to my distro, closed source.
