Stock crashed, then delisted... now what?

I owned a TSE-listed penny stock (SKG Interactive) which crashed and burned. Before being delisted from the TSE, it had fallen to a few cents (from a high of about $1).

I can’t seem to find their website. If the company has totally disappeared, can I claim a capital gains loss on my Canadian tax return? Do I need some kind of company death certificate?
