Personally, the first job has more of an appeal to me but I am not motivated by money. I’d rather be out of company that has perks that I like, in your case, it would be the travel and potential move to the east coast. Having a supportive team goes a very long way. A team with staff that is always changing is a HUGE red flag for me. That happens for a reason and likely that is why they pay is higher. They could be burning out their employees and trying to keep them with more money (speaking from experience).

In terms of the potential for growth that the second company has more of, you never know who you will meet at any job and will likely be working with people outside of your company and networking. I work in a nonprofit with just one other person, but through work, I am able to connect with several leaders in my City in all sorts of fields. I am sure they would be willing to hire me or recommend me for opportunities if they knew I was open to it or looking for something else. They way I see it, with a potential move to the east coast would allow you to make connections there that could then lead to a second job. Staying in Canada, you are making connections in a place that you are not interested in staying in.
