Just a warning to anyone interested in the coming eclipse. Avoid the glasses sold at Canadian Tire. I just bought two pairs of eclipse glasses at Canadian Tire. I decided to test them right after I got outside and immediately noticed an issue. Both glasses have a hazy appearance around the sun.
With proper eclipse glasses the sun should appear crisp and not too bright. You should be able to distinctly see the edge of the sun and even see detail on the surface. There should be no haze of any kind. If you see any kind of haze, immediately take off the glasses and throw them out.
I knew the glasses from Canadian Tire were suspect because they had "NASA APPROVED" on the sides, which is why I bought them. I wanted to test them.
There is no such thing as "NASA APPROVED". NASA doesn't approve or certify anything. If you see that, it's a massive red flag.
One very good trusted source for where to buy eclipse glasses is the American Astronomical Society which has a list of trusted vendors. I myself bought a bulk quantity from solareyewear.ca and have tested the glasses to be working properly.

Unfortunately, there will be a massive amount of scams going around with eclipse glasses and shady people trying to make a quick buck. Don't risk it and make sure your glasses will protect your eyes.
If someone tries to convince you that their glasses are genuine because they have ISO-12312-2 printed on them, it doesn't matter. I could print that on a pair of toilet paper rolls taped together, but that doesn't mean it'll protect your eyes.

Damn I was procrastinating and was hoping to go out and find them locally at a Canadian Tire or Home Hardware or something. I ordered a set just now from what appears to be an authorized seller through evilzon so I can test them in time. Thanks for the heads up
I'd watch out for anything safety related on Amazon. They've been found selling fake smoke/CO2/CO alarms, fuses that blow at more than twice their rating, and in 2017 they did a major recall on their solar eclipse glasses.
And unless it's name brand, most things that plug into the wall from amazon lack proper safety certifications too (power bars, extension cables, etc). Many will print the logos on them, but when you look them up they have zero certifications and aren't recognized by those authorities at all.

I got the Helioclipse who was on the list and the amazon seller was on their list of authorized sellers. I tried them out today and could literally see nothing but the sun, total blackout. think they're good. thanks
Glad I could help!
Edit: I see now that you had already ordered. I was glad to be part of this journey nonetheless.
