Not quite, and for 2 reasons:

1. I'm not sure if it is the same in Canada, but in the US it is only a 'precedent' if ruled by an appeals court, and
2. The Judge found the Defendant had a history of tersely accepting agreed upon (by later full completion of) contracts. If, for example you had texted me a similar contract and historically when you did I typically answered "yes, I agree to these contract details. Expect Flax in the Fall", but one time I texted 👍and then a day later said "nah, I don't agree to this contract" you'd have a case but I'd almost certainly win under the same Judge because now the argument 'the 👍 was just confirming receipt but not approval of the contract' holds water.
