Thank you all for the reply and very informative discussion. Many students go to Canada under Study permit carrying Max Cad $ 10,000.00 and never intercepted by the Immigration in Dhaka and many PR holders who already in Canada have taken Cad $ more than 10 Thousand first time they traveled to Canada.
About the mobile, if I any model of Samsung max price not exceeding BDT 10,000.00, will it work in Canada (bought from Bangladesh)? Please shade some light on it. In google it is written that -
"All networks in Canada cuurently support one or more of GSM / AWS / UMTS / HSDPA / LTE . North American GSM uses 850/
1900 MHz , UMTS/HSDPA 850/
1900Mhz, LTE 1700/2600, AWS 1700/2100 frequencies. Makre sure your own phone is compatible with these frequencies"
