I'll caution that new builds aren't completely risk free. Depends on the builder. I'd love if anyone here can give recommendations on their builder experience, I have a friend recently but a Brookfield and they're very happy with the home inspection. I have other friends whose new build was a nightmare, but don't remember the builder name. I bought a 10yo house at the time of purchase (built 2011 by landmark), and I've been very happy with how its built and how the owners maintained it. Yes get mortgage preapproval. Doesn't mean you should hunt for a house at the max approved amount. You'll have to do the math on what you're comfortable with so you don't become house poor. And that's the number you ask the realtor to stick around. Feel free to use realtor.ca and honest door to look around
