I don't want to download anything extra - I need a site where I can log in, choose a table and immediately get involved in the game. The main thing - that everything worked correctly with Canada and payments did not slow down.

You should definitely try https://tooniebet.ca/ca/live-casino/roulette — the choice of tables is quite decent, everything loads and starts quickly, and the interface is clean and not overloaded. Playing roulette with live dealers really gives you the authentic feel of a real casino, plus the withdrawal of money is fast and never delayed.
