Answer to your last question, Canada is 60 hz

You should be more worried about if it'll work with 240v, 60hz
It will run faster than the rpm's stamped on the nameplate. Which means it will run in accordance to 60 hertz motors, ie., 1725 or 3450 rpm in most cases.
The voltage is nominal 220 and running at 240 should make no difference.
It should theoretically run cooler, as 50 hertz motors have less cooling from fan rpm's if so cooled, or made with more iron to act as a heat sink if not fan cooled.
What horsepowers ?

You should be ok. The motor will run a bit faster, 20%, but the increased frequency will raise the inductance (?) of the motor limiting current. If you smoke the motor then you needed a new one anyway

Nominal voltage in the US is 120v/240v NOT 110v/220v. 220v hasnt been used in the US for decades!
Nominal versus actual. Nominal refers to that which is used in common parlance. Like a 2 by 4 isn't actually 2 by 4.
Actual voltage can be as high as 125/250 often times during summer months.

Lol no. A nominal 2x4 is 2"x4". It's dimensional lumber which is not 2"x4".
Measured is different than supply voltage. Everything is designed, engineered and specced to deliver 120/240. Of course that can vary by a few volts.
You wouldn't call it 112/224, so it's no more appropriate call it 110/220 which is not used here.

Ok sounds great but it's not running 240 with 2 hots, it's running 240 with 1 hot 1 neutral I believe. Right? Or is that irrelevant?

Think of voltage as the difference (potential) between two numbers, not a single number.
240v in the US is typically two 120v legs, 180 degrees shifted... so when one is +120v (RMS) the other is -120v for a difference of 240v.
In some areas/applications/etc, 240v (or 220v/230v/etc.) is one neutral leg (0v) and one 240v leg. 240 - 0 = 240v. Distribution/etc. is different but the final result at the device is the same.
A potential concern would be changing something with neutral tied to ground to suddenly having two hots, as one hot could then be grounded to the chassis. Electrifying a big metal appliance/tool is not a good idea
So I'd make sure that is not the case.zmaxmotorsports

Thats a good question,I know they use 240v stuff instead of 120v in germany anyway.
Never stopped to think about how it was actually wired though.

If youre talking about the tool the OP has, theres no way any of us could tell without seeing it or the spec sheets.

Most anything we have here in the states would require a voltage converter to work over in europe, eg a hair dryer or iron or coffee maker, electronic devices and the such, with the exception being chargers rated 110-240 50/60 hz. like your computer charger possibly. It would tell you on the name tag rating. That could be designed to handle 120 with a neutral or 240 with a neutral if that's what is over there. Could you plug it into a 20 amp 240 volt receptacle here? Even if you just made up a standard receptacle with 2 hots (obviously not legal) would it still work. I'd put money on it not working and possibly blowing the transformer.
I guess my real question is does euro voltage have 2 120 volt legs or 1 240 volt leg and 1 neutral?

No. Nominal refers to name only. From the Latin Nomen.

Also if the tool is rated at 220 volts, possible in europe, hooking it to 240 volts here would be providing it with too much voltage, could let the smoke out. Imo.

To prove that hook something up rated for 240 to a circuit of 277 volts.

A great many motors and other appliances were rated 220 volts years ago, and continue to this day to run on 240. For all practical purposes there is little difference. I can think of nothing right off hand that would not run adequately on 240.
As to running 240 volt (or 220) motors and such from overseas, if neither lead is grounded, it should run OK on our 240 volt system.

when we buy motors for our products, we have then "dual name plated". The motor manufacture will list the operating specs for both 240/460 and 60hz/50hz and the appropriate hp,current and rpm data.

Could it potentially affect rotation?

We used to run 240 volt welders off of 277 all the time,not a big deal.
Interesting.

Rotation is not set by frequency. Its set either by motor design, or start circuits. Many motors are reversible by interchanging leads.
