@ann58 My parents did similar via slow transfer annually to kids to keep below donations tax and reduce inheritance tax. It’s like prudent planning along with trusts if fixed assets are substantial.
Anyway.. TFSA has a max contribution limit, so I guess it is maxing your cash(hold/bond account/non-tax interest limit) and maxing general equities(non-tax investment limit).
The remainder you can decide if worth putting into RA as a once off bonus contribution which will reduce your tax (again to the limit according to income) or park in a discretionary investment but this will attract annual tax. The strategy would be the bleed this into TFSA and/or RA as quick as possible to remove tax liability.
If parent has multiple kids they usually either round robin kids Ie 100k to kid 1 year 1, kid 2 year 2 etc or divide up and contrib that way as a 100k/number of kids. It actually is beneficial as a slow contrib as then limits aren’t breached.
People often use other accounting tricks such as loans(you have to have interest on loans else it’s not a loan.. they getting tough on gimmicks) but it comes with costs and honestly unless there is a finite time to get this done why the rush. It’s a long term objective so hasty transfer is kinda excluded by definition I’d think. Via trusts is another way but unless the parent did so from the offset, ie planned when purchasing etc post fact is costly again esp if only reason is tax avoidance.
