Most police in Ontario can't tell the difference between DOT, Snell or CSA, however the majority do know that beanies are illegal and it's very probable that you will be stopped and fined.
Ontario has reciprocal agreements with most states, what ever you get charged and convicted for here most likely will show up on your abstract at home.
If you do get caught and issued a ticket, and you opt not to pay the $110 fine, an Ontario drivers licence number is generated for you and that new licence gets suspended... The next time you get stopped riding through our fair jurisdiction you can be arrested, get an automatic court date, fined a minimum of $1000, and be ordered to serve up to six months in jail for extreme cases.
You can get more time in jail here for driving under suspension than you would for carrying a weapon... go figure!
You cannot drive in Ontario using a licence from another jurisdiction when your new generated Ontario licence is under suspension, even if you've never been issued the actual document.
If there is no one at the roadside to ride your bike away for you it probably will be impounded.
It may not be what you want to hear, but obviously my opinion is a little different than others here.
