In Canada both are CKC sanctioned events (in the US the WCs are breed club based). The WC is easier than the JH, and only requires one pass to earn, so it would be a good place to start. You must do the levels of WC in order as well--you cannot just jump right to WCX--a WC is a prerequisite to enter WCI and so on. A really common sequence that Canadians follow is:
1. WC( straightforward singles, 2 land, 2 water dog does not need to be steady),
2. JH (3 passes needed for CKC title, 2 land single, 2 water singles, dog does not need to be steady),
3. WCI (simple doubles land and water, and steady),
4. WCX (walkup land double, honour on walkup, land blind, water double and water blind),
5. SH (land double, land blind, quartering test, water double, water blind, and an honour),
6. MH (land multiple, land blind, quarter to flush, water multiple, and water blind, and honour)
If you are not already a CKC member consider becoming one--you can get access to the rulebooks through the members only section of the CKC site (otherwise you have to pay for a hard copy), and need to either be a member or pay a title recording fee foor your dog if you want to get the title certificate. As a judge, I will say this--get a rulebook, and read it and re-read it. You need to understand the rules before you run your dog. I would also advise you to go and watch a test before you run one. This will give you a better idea of what to expect. Not sure where you are located to give you advice about other tests that may be coming up...
