No reason you can't. You are the petitioner for her, the beneficiary, to come to the US; she'd be the petitioner for you, the beneficiary, to come to Canada. Different people doing different things. The premise of either application is that you'll live in the sponsor's country. You will live in Canada if (more likely when) Canadian PR is granted for a little while. It could potentially afford you guys as a little family of 3 to make some more premeditated decisions about the move to the US. Maybe you guys will change your plans a bit and stay in Canada long enough for your wife to gain citizenship and then move to the US. You can always pause that I-130 for a bit after it's approved. It's just another avenue open to you.
I think 14mo for Canadian PR is a bit pessimistic - hopefully you'd be in the top 20% that go through the process faster. If you were actually willing to work in Canada, there is an Express Entry option for skilled workers. 6mo for PR.
That said, the I-130's in the US are taking a year or more for approval. Then there's the DS-260 to contend with and a medical and an interview. You're looking at 18mo at a minimum and that will also depend on things like a CRC and any documentation required from your wife's home country. I'd imagine she has most of those ducks in a row to have obtained Canadian PR, but you never know. USCIS and the DoS can be fickle.
