You won't be able to find the exact information you need online as there are a number of specifics to take into account when tariffs are calculated (trade agreements, country of origin, whether goods are available in your own country, classification etc).
The best way to get specific information for the goods you wish to import is just to ring the Canadian Border Information Services:
Calls within Canada
Toll-free: 1 800 461-9999
TTY: 1 866 335-3237
Calls outside of Canada
(Long distance charges apply)
(204) 983-3500
(506) 636-5064
Or you could contact a customs broker - it's safest to use a broker for the first import anyway to avoid getting penalty charges for incorrect documentation.
