They do not sell Mits products in Canada in audio and video they pulled out about 8 yhears ago. However the head office is located in Markham Ontario you could give then a call.
If you bought online or were able to import into Canada I would expect you would have no warranty and no one to service the set. This is a big risk when you consider you would be paying $3to 4,000.00.
I would suggest that you focus on some other set.
I own and prefer a toshiba and this year they have two models in the same size of screen in the 50,57 and 61. I would go for the higher model which gives better performance and costs about $700.00 more. The models can be viewed at www.toshiba.ca or www toshiba.com. I also recommend the pioneer which as somewhat more expensve .They have an elite seies which is excellent but pricey,but their normal line gets excellent reviews.
Good shopping
