Canvas Notifications Not Working? Here's How to Actually Get Reminded

If your Canvas notifications are not working, you're not alone. The default Canvas notification settings are weirdly conservative, and a few wrong toggles will leave you completely silent on assignments, announcements, and grades. Here's how to fix it — and the harder truth about what to do after you fix it.

Step 1: Fix your Canvas notification settings

Canvas has two different notification systems that confuse almost everyone:

Account-level notification preferences — what gets sent and to where.
Course-level notification preferences — overrides per course (newer feature).

Start with account-level.

On desktop

Click your Account icon in the left global nav.
Choose Notifications.
You'll see a table of every notification type (assignments, announcements, due dates, grades, etc.) with channels across the top — email, push, SMS (if added).

Set these to Notify me right away at minimum:

Due date
Assignment created
Grading
Announcement
Submission comment

Set these to Daily summary at minimum:

All submissions
Late grading
Invitation

Leave the rest off if you don't want noise.

Add a phone number for push or SMS

In Settings → Ways to contact, add your phone number if it isn't there. Canvas push notifications only work if you've installed the Canvas Student app AND signed in there. SMS notifications require your school's Canvas admin to have it enabled (many don't).

Course-level overrides

If only one class is silent, check that course's notification settings (Course → top-right toggle). Some professors mute announcements by default.

Step 2: Fix the device side

Even with Canvas configured correctly, the OS layer often eats notifications.

iOS

Settings → Notifications → Canvas Student → Allow Notifications ON.
Make sure "Time-Sensitive" is allowed if you want them to break through Focus modes.
Check Focus / Do Not Disturb schedules. The Canvas app is exactly the kind of app DND silences.

Android

Settings → Apps → Canvas Student → Notifications → enable.
Battery optimization: set Canvas Student to "Not optimized" or "Unrestricted." Aggressive battery managers (especially on Samsung and Xiaomi) kill the Canvas background process and you stop getting pushes.

Email

If you're routing notifications to your school email, make sure it actually forwards to wherever you read mail. School inboxes are infamous for being checked once a week.

Step 3: Restart the Canvas app

Genuinely. Force-close it, reopen, sign back in. Push token registration breaks regularly after iOS updates.

Step 4: The honest part

Even when Canvas notifications are working perfectly, there's a deeper problem.

You already get hundreds of notifications a day. Group chats, Slack, Instagram, BeReal, your bank, your delivery app, your gym, your roommate's TikToks. Your brain has trained itself to swipe away banners without reading them. This is called notification blindness, and it's been measured in studies as something like a 70% miss rate on notifications that aren't urgent-feeling.

A muted gray banner from Canvas at 3:42 PM that says "Marketing Final Project — due in 6 hours" looks exactly like every other notification you've ignored today. You'll see it. You'll swipe. You won't register what it said. You'll find out at 11:58 PM.

This isn't a Canvas bug. It's the entire mobile notification system doing its job too well.

Step 5: Stack a reminder channel that breaks through

The fix isn't more banners. The fix is a different channel — one your brain hasn't been trained to ignore.

A phone call is that channel. A ringing phone bypasses notification blindness because:

It's audio + tactile, not just visual.
It demands a binary decision (answer or decline).
You haven't gotten 400 of them today.

This is the entire design idea behind ClassCaller. You connect your Canvas calendar feed and pick when you want to be called — a week out, an hour out, 30 minutes out, whatever it takes. You can also customize the voice and tone, including an Unhinged Mode if you need someone to yell at you. The free plan covers 3 calls a month, which is enough for the assignments you genuinely can't miss.

Quick checklist

Canvas account → Notifications → set Due date, Assignment created, Announcement, Grading to "Right away."
Phone number added under Ways to Contact.
Canvas Student app installed and signed in.
iOS / Android notification permission granted to Canvas Student.
Battery optimization disabled for Canvas Student (Android).
Time-Sensitive notifications allowed (iOS).
DND / Focus mode exception for Canvas (or the assignments you'll miss are exactly the ones that fall during Focus hours).
Plan B in place for the deadlines that actually matter: an external channel like ClassCaller that calls your phone.
