An exchange between my accountant and me illustrates

ACCOUNTANT
Any digital news subscriptions for which you kept receipts? (i.e. online Globe and Mail, online Toronto Stars, online National Post subscriptions, etc..)?

I HAVE ABOUT $100 A MONTH IN SUBSCRIPTIONS TO DIGITAL PLATFORMS CALLED SUBSTACK NOT TRADITIONAL NEWS PAPERS

ACCOUNTANT
To claim the digital news subscription, the platform must be registered as a “Qualified Canadian Journalism Organization” on CRA’s directory. Substack is not one of them and won’t qualify.
