Buy Canadian

If you use a windows computer you could look into Linux. It's a bit complicated to get ahold of if you're not super tech savvy and are super used to Microsoft products but it is doable.

Look into what software, hardware, games, etc that you use your PC for and see if they're Linux compatible. If not, find alternatives that could work for you. (Example, instead of Microsoft office you can try LibreOffice)

For me as an example, I primarily use my PC for gaming. The Proton compatibility layer allows me to play all my games on Linux (except for Garden warfare 2, which won't run due to an incompatible anti-cheat software)

Overall, do your research, find how compatible your own setup is and what distribution is right for you.

For new users, Linux Mint is a popular choice.

Most Canadians live within 160km of the border. If you have nothing made or marketed left, I recommend stepping 5-7m closer to the border and screaming. Maybe warn your neighbours first?

It's a hard one but next is to leave their platforms as much as possible.

I'm currently De-googling / de Microsoft-ing and it's hard but feasible.

If you're not ready to leave Facebook, follow the guide John Oliver's team put out.

Otherwise, go see local comedians / bands or buy their stuff to support them, stuff like that

If you have any savings, investments, retirement funds, etc., make sure they're not invested in US companies.

Someone already mentioned apps, but another one to look at is cloud storage and email services, and switching to local storage(ie, hard drives) and/or non-US services if possible.

I feel ya...when capitalism is already such a cancer that I already participate as little as possible, boycotting becomes harder because I was already not giving the parasite class my money.

There's Crave I think? But the deal ain't that great. There's a LOT of ads and they're extremely LOUD.

And the subscriptions are expensive. I'm not going to pay 22$/month just to stop having ads. I don't need the 4k streaming because my TV doesn't have that resolution. Besides I only have a 30mbps internet connection that's already costing me almost 80$. (I should shop around now that I think about it. 80$ is hella expensive for 30mbps)

This is a list of initial 3rd party scripts the cbc.ca website lists in Ublock. Akamiedge is Microsoft and google is well Alphabet and are both US corporations.

Maybe start complaining to your MP that tax dollars are funding US companies through CBC, and write to CBC to advise them to revamp their websites to not use US tech company infrastructure.

How are you doing on personal hygiene items like toothpaste, mouthwash, soap, shampoo, et alia?

Have you considered a vacation to mar-a-lago?
