Do the print heads current Canon printers clog up?

Having had some frustrations with Epson inkjets in the past, I was wondering
if the current Canon printers ever do this? I have been using lasers for a
while, but I need to get good colour prints now, and so I decided to get an
inkjet for general use.

If I use the colour printing rarely, I suppose they will get clogged up?
Would keeping the printer powered on reduce the chance of clogged print
heads? I would really like to avoid having to do that is possible.
