naked option margin requirements

It doesn't matter.
I'm asking about the formula used to calculate margin for selling naked calls. The standard formula for equities (not index) is the underlying * .30 (+-) the amount ITM or OTM - the premium received.
I'm just curious if that 30% is standard in Canada or if it's lower at some brokerages.

In the US there are two methods of calculating margin. Reg-T and CPM. Reg-T is cash based and CPM is risk based. To get a better idea of the margin required for a specific position, try these links.

CPM: http://apps.theocc.com/pmc/pmc.do
Let me know if you need any help with either calculator.

Thanks for the links.
In the first link the margin calculation is based on 20% - so I know that in the US their are brokerages that offer naked calls based on using 20% * the underlying in the calculation. I don't believe this is the case in Canada.
So to clarify my question, does anyone know of any brokerages in Canada that use 20% * the price of the underlying to calculate margin, or is 30% required by all Canadian brokerages?
