This can be tricky territory. If things continue in this platonic stage much longer, she will see you as nothing more than a friend and when it comes time for you to make a move she'll say something to the effect of, "I don't see you and I dating each other, but I really want to date somebody like you." Her trip to Canada will give her some time to miss hanging out with you and it may open a window of opportunity for you to smooch her when she gets back. Whatever happens, be cool with her decision and don't let things get weird between you two if she's not into having a relationship. She's a girl that likes hang out and ride old bikes and that's tough to find.
