Can my mom enter Canada with a one way ticket?

[mbassamh]

Hello every one,
I am from Lebanon. I got my student visa a month ago, and my mom got her visitor visa for multiple entry for 5 years. My problem is with flights booking. Do I need to book 2 ways ticket for my mom? or a one way would work as she has a multiple entry visa for 5 years? Any one knows if we will have problems in the airport if we book one way ticket? Do airlines can refuse in the airport if we wanna travel with one way ticket ? Pleaaaaaaaaaaaase help me if any one has any information about this issue or have done something similar in the past.
I need a reply as soon as possible please as I need to book my flights.
Thanks.

A 5 year multiple entry visa doesn't allow her to stay five years. She's still only allowed to visit for six months. Once her six month visit is over, she must either leave or apply for an extension (no guarantee the extension will be approved).

The airline might refuse her boarding if she only has a one way ticket on a visitor visa.

Not a good idea to buy one way ticket. Canada Immigration gets the booking records of all visitors. Having a one way ticket will make officers suspicious of her intentions. They might think she intends to overstay beyond the six months.
