Hello fransky .. welcome back! I know ZERO about the Canadian system .. BUT I am a great "googler" .. so here is what I would do if I was you:
1. read through ALL the pages of this Forum .. you will be amazed at the knowledge you will pick up .. make notes about what you think may be relevant. Personally I cut and paste into my "Word" computer program . then print it out as a reference when you meet with your doctor.

2. I googled "TIPS ON GETTING A REFERRAL TO A SPECIALIST QUICKER IN THE CANADIAN SYSTEM" .. I didn't read through any of it .. but was AMAZED at all the threads that came up!! WOW! Not surprised! Anytime you have a "system" .. people have figured out how to work it! SO .. YOU be smart and work the system .. just figure out how!

3. MOST importantly .. even IF you DO get a MAC diagnosis .. yes it IS pain in the batooty!! BUT it sure could be a WHOLE LOT worse!! Come on .. count your blessings .. it is NOT incurable cancer .. it is NOT SO many really horrible things .. PLUS you found this Forum of people who will walk you through it. Personally .. I was diagnosed in 2007 .. and have been stable since May 2014 .. AND am leaving on a WONDERFUL trip 8/31 to have a WHOLE LOT of fun in life! There IS life after the diagnosis. AND THAT IS IF you get the diagnosis .. as I said .. don't put the horse before the cart .. count the blessings you have in your life right this minute .. be kind to yourself in this period of time .. and know that we are all here for you! Sending you yet another hug! Katherine
