Camera equipment (including digital and video) is exempt from duty no matter which country it is imported from.
You can find the tariff rates on almost anything here:

However, if your goods are shipped by ground, expect to get charged duty (and brokerage) regardless. The morons that work for the ground shipping departments of companies like UPS charge whatever they feel like, and you have no choice but to pay if you want the package. If they do charge you duty when they shouldn't, you can request a refund of the extra charges from the CCRA, but it can be a lengthy process.
Paying a few dollars more up front for air shipment will almost always cost less (usually, a lot less) in the end than ground shipping (unless you're talking about using the post office).
