额，说得不清楚么~~~~现在是已有美签，准备签加拿大，估计加拿大也是签单次的，到达和离开都是加拿大.....简单来说，就是单次的加签能不能去趟美国再回来

可以，去年我用一张加拿大单次签证往返美国了三次，最后从多伦多回的国。

Single-entry temporary resident visa

If you have a single-entry temporary resident visa, you will generally need a new single-entry visa to come back to Canada.
You can request to return to Canada on your original single-entry temporary resident visa, if:
you will only visit the U.S. or St. Pierre and Miquelon; and
you will return to Canada before the end of your approved stay in Canada.

Multiple-entry temporary resident visa

Yes, you can come back to Canada, if you have a multiple-entry temporary resident visa and it has not expired.

ls你给的链接只是说明往返加拿大的情况
如果你只有加拿大旅游签证没有美国签证绝对不可能进入美国

去美国当然得有美国签证了
