Canada Single Entry Visitor Visa問題

父母持一年有效多次往返B2來美。欲為他們辦加拿大旅遊簽證。
按使館網頁上的解釋(原文附上)，如果我父母隻申請single entry visa,
假設入加國境時給6個月簽證，這期間來回往返美加兩地應該都無問題？
我的理解正確嗎？多謝回複。

A single entry visa allows you to enter Canada only once. This visa may also be used for repeated entries
into Canada from the USA or St. Pierre and Miquelon provided you do not enter another country. Such
entries must occur within the time validated for your stay in Canada. For example, you may be given six
months from the date you enter Canada at the port of entry.
