Am I competetive enough?

Hi! Applying in Sept 2027 Cycle. from Ontario, Canada. Planning on applying to schools in Canada as well as, select few in US. I have a 82% Cumultaive avg, this year i predict to have a 84% approx as well as simmilar next year as i am only really taking electives. I have been a volunteer for persons with aphasia once a week, for over a year as well as, I did some research with them too. I am also working with a professor at my university as a research assistant, who is very published in communication disorders. I presume I will be published with her lab as she has said she wants me to work on publishing papers and things with her. Is this competetive enough? Do i need more or, something else to make me a better applicant. Also planning on applying to CDA as a back up.
