One of the hardest parts about getting an Android/Google phone is that there are many, many, many choices out there. To help you decide Google has set up a questionnaire that will help you decide which phone is best for you and your needs. I took the survey and it was pretty accurate to what I currently have (the Nexus 5, which is no longer available so it wasn't a choice).

This is a US based survey so the last question will be the option to choose your carrier - obviously these carriers aren't in Canada, but you are given the option to skip this question.
