Trump will have a huge influence on Canada. Hopefully Canadians will resist a right wing surge in the next election.
The immigration thing has already started. Even on fairly liberal websites where the comments are generally pro-Trudeau and anti-Trump, the same commenters are generally anti-immigration, anti-global trade (e.g. TPP), etc. So the whole anti-globalist/protectionist theme is definitely occurring here, too. Most of the opposition I've anecdotally heard to Trudeau is purely on immigration... the budget stuff, even the carbon taxing or environmental regulation... some opposition but generally taking a wait and see a little bit. It's really just immigration that I hear or see the most blatant is anti-immigration.
I think it comes down to jobs though... if the job market improves, it'll be fine. But jobs numbers, especially sans B.C., have not been great, and most of his economic policies (whether they're good or bad) are more long term so it's hard to say if he's going to create any short term jobs boost.
Then in Trump starts messing with NAFTA... that's just going to have an immediate effect on jumps and then promote Trump-style anti-immigration sentiment here.
That, if the US economy runs into trouble, it could actually stymie the anti-immigration sentiment here by showing that it failed to improve the US economy.
At the same time, if Trump does tax more imports from countries like China, those countries may begin to trade more in Canada. You could see more investment in Canada, more acquisitions or expansions (or trade in general) switch from US to Canada. More skilled immigration (regardless of their negative sentiment growing against it) could also benefit the economy.
It'll be interesting to see what he does with NAFTA though because despite general NAFTA opposition, he's also expressed some positive support for Canadian trade -- namely oil. Could be good for Alberta, bad for Ontario....
BC being the wild card with softwood lumber currently being negotiated but I'm not sure if Trump will really get protectionist on lumber because while US mills dislike Canadian lumber, US builders like our cheaper wood. And Trump could favour US builders to make sure real estate doesn't crash from inflating lumber prices (because cheap Canadian lumber exits the market). Probably also good for film/tech/entertainment in VAN, TO, MTL... more firms, more skilled immigration, etc.
In some ways, Trump could fuel some of the anti-immigration sentiment occurring in Canada but he could also directly benefit a lot of specific Canadian sectors and even Trudeau policies, and in general just make Canada a more appealing destination or partner for trade, investment, immigration, etc.
