Hi Mulligan,
The fuel you have to have overhead destination WITHOUT a destination alternate is made of:
The final reserve of 30min that you mentioned PLUS
15 min Additional fuel as stated in EU-OPS Appendix 1 to OPS 1.255 Para 1.6 "Additional fuel".
(b) Holding for 15 Minutes at 1500ft (450m) above destination aerodrome elevation in standart conditions, when a flight is operated without a destination alternate aerodrome;
Of course, this might be different in Canada...
Hope this helps ;-)
Dan.
