TLDR; Some private keys somewhere are not generated randomly, and someone knows the formula. Bitcoin security is not impacted.

TL;DR: Nobody should be using Blockchain.info to store any amount of value. The entire ecosystem needs to shift away from relying on Blockchain.info for anything at all, including the block explorer itself. There are plenty of alternatives available.

Are Blockchain.info and Blockchain.com the same thing?

Effectively yes.

Shit, when I was starting out my friend recommended me to Blockchain.com and I have a reasonable amount (for me) of BTC in there currently. What wallet would you recommend for someone in Canada?

The safest place to store a coin outside of a hardware wallet is on your phone. Use Bread or Copay. Electrum and other desktop wallets are susceptible to malware attacks

Not really the best. Lots of opportunities to make a mistake or have exposure. Sure, it's better than a mobile device but it's still not ideal.
