Hi Jean,
I looked into insurance for my gear last year and from what I saw, they are the most solid choice for canadians. The company offering this insurance product is Essor (or used to be named Essor) and they were recommended to me in the past as the most complete solution for photographer for all things liability on a shoot, travel, lost equipment... The price also seem pretty reasonable for what they offer.
I haven't purchased their product yet but I called them in the past and they are knowledgable and friendly.
hope it helps!
Julie
