You'd better buy it in Canada if you'll land.

中国用的是GSM，加拿大是PCS，不能通用。不过可以买3频手机。但是有一点要注意，这边很少有公司是使用SIM卡的。一般是通过机身串号识别。具偶所知，只有FIDO是用SIM卡。而且不同公司的机器不兼容（偶特别讨厌这点）。

sorry , GSM is TDMA, one of PCS,
in North America, got FDMA,TDMA, and CDMA in market, it can autoswitch and transferred smoothly without problem.
Fido is TDMA system. Telus, Bell got both CDMA and TDMA.the keypoint is the cellphone is as a part of service, called free under service plan, typically 25$ per month for 150min. one year contract.

but why the cell phones from China cannot be used here? Is that means they work with difference frequencies?

you are right. in canada there is also GSM network,but the frequency is 1900m. in china,the operaters provide 900m and 1800m network.that is why if you got a three frequencies(900m,1800m,1900m) cell phone in china you can also use in canada

找广告，这里的手机事是免费的，交月费，送200分钟/月，超过200分钟再计费。多用多交。
