The official page for people new to Magic the Gathering.
The "mothership", AKA the main site for everything related to MTG.
This is a searchable database of every Magic card to see print. This is invaluable to refer to when building your decks outside of Arena.
The official homepage for Arena in specific.
This article by Frank Karsten for channelfireball.com is a must read for anyone new to the game of Magic the Gathering. It may be a bit heady at times, but you really can just skip the text down to the relevant data tables you need. I bookmarked this page to refer to whenever I make a deck and get stumped on my mana base.
Another article by the brilliant Frank Karsten for channelfireball.com. This is another must read if you are new to Magic or Arena, but you should probably take a look at it after the other one. This is another excellent bookmark to keep and refer back to as you build and adjust your decks.
MTG Goldfish compiles deck, card, and win/loss data for major MTG events and shares it online in a very easy to comprehend way. I tend to go into the "DECKS" section and from there I can check both the most commonly played cards in a given format like Standard (which is the same as Arena here) as well as the most popular decks.
Lots of great strategy and analysis, as well as a good place to shop for MTG singles and other products.
An online deckbuilder that allows you to make your decks with any card ever printed and playtest them in a solo simulator to see how they draw and play. The site charts almost everything you need to know about the decks you save on it and the site offers a great mobile app I use all the time.
Make your own custom Magic the Gathering cards (or even a full set or two) that look just like the real thing! This entire site is intended for fun, and any cards you make and actually print out would have to be played with in casual games.
A bit of a rough place, but good for the getting the latest in MTG news as well as access to how people actually talk about the game. Plenty of information to be found here.
Subreddit for Arena in specific. Good for news and analysis.
"Spikes" are competitive MTG players looking to build the best decks to win. This subreddit is for you if that's your goal. A much rougher place than the usual Magic subreddit, and they are very strict on their posting rules.
Face to Face Games Toronto, in specific, but they are based out of Montreal too. Their website is easy to use, ships internationally, and their prices for Magic the Gathering and most other products are exceptionally good.
The owner, Kelly, is one of the most decent people I know, which is always nice to find in a business and especially a community based one like a game store. If you're in Toronto, this is THE place to place Magic the Gathering, and other games like it, as far as I'm concerned
2077a Danforth Ave,
Also in Toronto, also ships internationally. Great prices and a fairly mind-boggling selection of board and card games, although they don't focus on games like Magic as much. They do not have a play space of their own, but they are definitely worth a visit because of the incredible variety of stuff you can find there.
247 Spadina Ave,
A&C used to focus more on video games before they got into board and card games in recent years. They now have a wonderful dedicated games section of their store and their selection for both cards and video games is great.
452 Spadina Ave,
