A large number of people -- millions, at least -- are related to royalty. That doesn't mean that they have any right to a title or royal status themselves.
If you were closely enough related to the male line of Norwegian royalty to carry or claim a title, you would almost certainly know it. If, however, your relationship involves a minor cousinship somewhere in your family tree, then that would be all you could say -- that you are a distant cousin of the Norwegian royal family.
You could be a cousin if you're descended from some younger son or if a daughter back there married a non-royal. Even if the non-royal had some sort of aristocratic title, the children wouldn't necessarily have any titles or wouldn't necessarily carry any heritable titles. Not all aristocratic courtesy titles involve titles for children, especially if we're talking about a female line. The children of younger sons in some royal families don't carry princely titles but may be given aristocratic titles, which can dwindle and die out over time.
I think you need a professional genealogist, someone familiar with royalty, to figure out your precise relationship to the Norwegian royals and whether there would actually be any titles involved. It's highly unlikely.
And if there were, if you wanted to use the title, the first thing you'd have to do would be to check into your ability to claim Norwegian citizenship. You'd do that through the Norwegian Embassy in Canada or through the consulate nearest you.
It wouldn't be considered very appropriate for a Canadian citizen living in Canada to swan around calling himself or herself by a Norwegian title.
By the way, even the British Queen has grandchildren (and one great-grandchild) and cousins who have no titles or royal status. Being related to a royal family doesn't necessarily make you royal or titled yourself.
