Advice on Traveling Within Canada, from Saskatoon, to Montreal, HELP!?

I am traveling to Montreal this summer, and I currently live in Saskatoon, Saskatchewan. I have questions such as, do i need a passport if i am traveling within Canada? I'm staying in Montreal for a month or two, possibly to work, so would it be cheaper if I bought a one way ticket both ways, or should i do a return flight as well? i was quoted about 460$ to get to Montreal, but nothing really specific. This is my first time travelling by plane, as i have always travelled by car. Please help! haha. If anyone knows the Cheapest way to get to Montreal, from Saskatoon, Saskatchewan, i would be deeply grateful! Thanks!

hello,

Contact the airline and ask about joining their "loyalty club".
this will get you on the track of better rates, specials, and better service that most passengers never know about or have access too.
And it's free.

Also ask the hotel where you stay about joining theri loyalty club too.

happy traveling.
