Does anyone have experience with the following? I'm not even sure what to Google (I've tried a few things, but nothing quite matches what I'm doing).

I'm going on a recruiting trip to Waterloo on Sunday.

As part of htis, I am bringing some items to give out to students as prizes, such as:

Backpacks
Google Home Minis
Paper notebooks
etc.

The total retail value of everything is well under $500.

Do I need to do anything special beyond just declaring it at the border? Am I going to need an itemized list for them to assess any taxes/duties?

Basically I just want to make this is easy as possible. I'm not concerned about having to pay any money (as it can obviously be expensed), but I am concerned about doing anything illegal
