Thank you very much for the very clear answers, both clw and Winston !
I have one more question related to this.
The amount you paid to obtain medical insurance (Overseas travel insurance) 'immidiately BEFORE' coming to Canada
can be claimed as medical expense ?
Does it consider as this ? Premiums paid to private health services plans including medical, dental, and hospitalization plans. They can be claimed as a medical expense, as long as 90% or more of the premiums paid under the plan are for eligible medical expenses.
