Not sure about Canada, but Wa st does have the enhance license talked about earlier. but that will not do the OP much good! Having a passport would be the BEST option frankly.
The how and if it makes sense.....you will have to figure that out base on what will assume at this time is UK citizenship, vs Ca to US. that could or could not add some time at least coming this way, ie south, going north, not sure about, lways seems easier to get into canada for us US folks. Getting back into our country of birth/citizenship....nuther story/ball game......but that would bring some politics into the matter!
