The answer is yes. If you're wondering where Stake is legal, you don't have to worry much  the Stake.us social casino is legal in every part of the US. This is mostly because Stake.us doesn't accept any real money deposits.
So if you want to deposit, play in and then ultimately withdraw crypto, Stake is an option for you in Canada, outside Ontario. You can buy your desired crypto balance from Stake with CAD if you like. But remember, Stake does not offer Canadian Dollar betting accounts or accounts in any other fiat currency.
