I don't know about attorneys outside of the UK but in the UK they cost an awful, awful huge amount of money. £500 an hour? That's the base to start from if you want an attorney who knows anything about websites and copyright infringement. If you want a good one £1,000 an hour is probably the base going rate. They charge for every single thing they do, including the time it takes them to fart if a fart occurs when they are doing work for you - probably extra if it's an especially fruity one.
Unless your website is a mega large and profitable one, attorneys are never a realistic option, in the the UK anyway.
The beauty of the small claims court is that you can take anyone / any entity to court and it will only cost you a small amount to proceed. The downside is that damages are also limited but if you win in the small claims court then your adversary is liable to stop doing whatever you took them to court for - even if they never pay the damages.
I'd say go for it and see what happens. Let us know the outcome coachm. I'm assuming the Canadian small claims system is similar to the UK.
