What I am able to find so far is that handwritten passports expire on Nov 24th 2015.
bangladesh consulate's webpage says this too.
quote 'All Bangladesh citizens, are encouraged to apply for Machine Readable Passport (MRP) and requested not to apply for hand-written passports as this type of passports will not remain valid for travel after November 24, 2015 as per the decision of the International Civil Aviation Organization (ICAO)".
why dont you call them or call CIC callcenter and ask them??

Identification requirements for international visitors
The Government of Canada requires that all travellers carry a valid passport because it is the only reliable and universally-accepted travel and identification document for the purpose of international travel.
When you enter Canada, a border services officer may ask to see your passport and a valid visa (if you are arriving from a country for which one is required). Visit the Citizenship and Immigration Canada website to find out what travel documents you need to come to Canada. We remind all travellers you must carry proof of citizenship such as a birth certificate, a certificate of citizenship or naturalization or a Certificate of Indian Status along with photo identification.
