根因分析
加拿大eTA允许5年内或护照到期前多次入境，但每次访问限于6个月，除非官员批准延期；快速前往美国不会重置时间——CBSA官员会评估累计停留时间，若怀疑有居住意图可拒绝再次入境
English
Canadian eTA allows multiple entries for up to 5 years or passport expiry, but each visit is limited to 6 months unless extended by an officer; a quick exit to the US does not reset the clock—CBSA officers assess cumulative stay and may deny re-entry if they suspect residence intent

-
Respect the 6-month limit per visit. If you need to stay longer, apply for a Visitor Record (extension) before your 6 months expire via IRCC online portal. Do not rely on border runs.
-
If you have a genuine need for longer stays, consider a Super Visa (for parents/grandparents of Canadian citizens) or a work/study permit for authorized activities.
无效尝试
常见但无效的做法:
-
90% 失败
Flagpoling (leaving to US and returning) does not reset the 6-month period—CBSA may reduce the stay to days or deny entry if they see a pattern
-
95% 失败
Assuming you can stay 6 months, leave for 1 day, and return for another 6 months—CBSA uses the 'totality of circumstances' test, including cumulative time in Canada
