Canada's economy is strong right now. Did you read that we are the strongest economy in the G7? I didn't think so. It's time for Trudeau to push ahead and allow it to go where it does. As for your amateur economics: there is no reason "everything must tick in unison." That's an unsupported statement that you're just pulling from your own head. 
In part, the stronger Canadian dollar is due to a weakening US dollar, and there is nothing that can be done about that. Whatever Trudeau does, he should not follow the insipid Harper mantra of "steady hand on the wheel," as it is total baloney. Whatever Harper did, he erred. Just look at the mess he left us. 
The economy is strong and strengthening; Canada can afford a strong dollar.
