关于加拿大、美国签证

请问，看到说：
If you intend to travel to the United States during your visit to Canada, you do not need a multiple-entry
visa in order to re-enter Canada directly from the United States during the period for which you were
originally admitted to Canada.
如果申请人想在访问加拿大期间前往美国，在加拿大合法停留期限之内从美国再次进入加拿大不需要一个多次入境签证

如果拿到美国多次往返签证的话，那对以上可以理解为：可以在“在加拿大合法停留期限之内从美国多次进入加拿大”么？

谢谢喽~~~
