根据下面这个官网信息,加拿大临时居民从加拿大访问美国,在原来的停留期内再返回加拿大可以无需签证。似乎可以理解为美国返回加拿大后沿用原来的停留期。

If you have a single-entry visitor visa
- In most cases, you’ll need a new visa if you want to leave and come back to Canada
- You can ask to return to Canada on your originalsingle-entry visitor visa only if:
- you’ll only visit the U.S. or St. Pierre and Miquelon; and
- you’ll return to Canada before the end of your approved stay in Canada.
If you have a multiple-entry visitor visa
- You can leave and come back to Canada multiple times as long as your visitor visa has not expired.
If you have an expired visitor visa
- You can ask to come back to Canada on your originaltemporary resident (visitor) visa, even if it’s expired, if:
- you’ll only visit the U.S. or St. Pierre and Miquelon, and
- you’ll return to Canada before the end of your approved stay in Canada.
但根据另外的规定,临时居民每次入境加拿大,如果CBSA没有注明停留时间,默认可停留6个月。从美国航空入境加拿大,航班对应的乘客名单和CBSA入境记录肯定是有的,又可以理解为入境可停留6个月。
所以这个最好和CBSA再确定一下可合法停留的时间。
