In Canada, a gift of shares to a child is a deemed disposition at fair market value. You realise the capital gain immediately and receive no cash with which to pay it — the opposite of the US treatment the Trump Accounts regime relies on. If the child is a minor, attribution rules can push subsequent income back to you as well.

There is no Canadian vehicle that behaves like the US one: an RESP accepts cash, not private shares; a TFSA can hold securities, but an in-kind contribution triggers a deemed disposition at fair market value and denies you any capital loss on it. The useful conclusion is the negative one. Ignore this mechanic entirely.
