This should probably go in the D&G forums.
Do it in the 18RG and maybe some of it on a 200 series aircraft, that will give you an advantage when you head out west. Unless of course if you want to just instruct, then having 50 hours multi PIC will mean you can get your META once you move up the ranks.
If you want to head out bush then chances of snagging a multi gig straight out of flight school is next to zero, though it has happened.
Living out west is expensive and you might spend quite some time without a job so save the coin for the start of your career.
Just my two cents.
